Nagravision 3(nagra 3/N3/Nag3) What is it?

Nagravision is an encryption method used by both satellite providers.
This locks and secures their channels so that only subscribers who have authorization can view.

Nagravision 1 and nagravision 2 (nagra 1 & nagra 2) have been compromised and exploited, allowing unauthorized access via hardware and or software to view their channels. Naturally when this happens the providers must find a way to lock their signals again, if only as a way to inconvenience you momentarily in hopes you will start to pay.

What about new software?

No one knows this information besides the coders. They will not disclose to much info before hand.

If it does get cracked, how long will it take?

Again, the same thing applies. We simply do not know.
We do know however, the switchover from nagra 1 to nagra 2 was only a matter of a few weeks. But this may not be as easy as last time. Only skilled coding teams will know what it takes. Most of the upper/common coders,or spokesman's for them have already stated that they are working on it. As soon as the files are finished we will have it posted.

What channels have already switched over to nagra 3, thus resulting in a black screen?

Bev is currently blacked out, shutting off the lights to nagra 2 and only using nagra 3 as their encryption method.

DN will follow, they have to be sure all their subscribers receive their new access cards first.

Remember,there is a whole sky up there full of channels that in many cases are free and clear,using 0% encryption.that's why your receivers are 100% legal.

So in short the dark days are ahead and only coders releasing new software for nagra 3 will turn the lights back on.

The N3 switch, what to do & what you should not do...

Some of you have never seen a nag switch.
We all know the providers are switching to N3. You will lose more & more channels until they are all gone. You will get scrambled channels, sound but no video, ect. All that is to be expected during a switch, there is nothing you can do about it except making sure the channel loss is not on your end.

As time goes on, rumors will surface like you have never seen. You will also see many scams.

Example:
We almost have the fix, but ran out of money..
Your receiver won't work for N3, buy this one...
Keys will work... just register and donate...
Exclusive Nag3 fix, use PayPal.....

Keep your old receivers, we don't know what will work & what won't. If you have to have a new unit, buy a $100 one until this is over..

We have experienced staff, that have been through these changes from the F card to N1, N2 & now N3.
We know where to look for bins & info, We have enough experience to know fact from rumors & scams.

More info on N3:

Nagravision is a company of the Kudelski Group that develops conditional access systems for cable and satellite television. The name is also used for their main products, the Nagravision encryption systems.

Three versions of Nagravision are in common use for digital satellite television, known as Nagravision, Nagravision Cardmagedon, and Nagravision Aladin. Nagravision Cardmagedon and Aladin are often confused with each other. Nagravision Cardmagedon is however, a complicated combination of Nagravision Aladin and Mediaguard SECA 2 encryption.

The decryption unit is either integrated into a receiver, available as a conditional access module (CAM), or as one of many encryption schemes supported on a CAM emulator.

Nagravision has been adopted all over the world as a conditional access system, with providers like Virgin Media in the UK and Dream Satellite TV Philippines (on Nagravision 1), Polsat of Poland, Digital+ Spain, and some in Germany, (now on Nagravision 3), TV Cabo Portugal, Premiere Germany, Digi TV Romania, B** TV and and Dish USA (On Nagravision 2).

The original Nagravision 1 is now almost obsolete after it was originally compromised in 1999, although Dream Satellite maintain relative security by changing keys several times throughout the day, causing great inconvenience to unauthorized viewers.

The Nagravision Aladin providers have been confronting the issue of satellite signal piracy and smart card piracy, since the system was publicly compromised in summer 2005. At first, security of the system was regained, with software revisions, manipulation of the Nagravision encryption algorithm, along with the phasing out of older cards, like the ROM101, ROM102, ROM103 in USA and ROM110,ROM120,ROM130 in Europe, in favor of the newer ROM142/ROM180.

Card hackers have, however, continued to compromise the encryption system, with continued software and key releases being made available to the public. Software emulation of the Nagravision system has been implemented in many Free-To-Air Satellite receivers, allowing unauthorized viewing to those who do not own an official card. As of the summer of 2008, the next version of Nagravision, nagra3, has been compromised in Europe.

Nagra 3 will be the same Nagra 3 here as there. There will be changes in map calls & timers like there is now. As Nagra 3 is cracked in parts of Europe it will be cracked in other regions as well. That does not mean there will not be upgrades to the code. There will always be that.

The real question is , will your current FTA unit handle the upgraded code?

The reason we have to wait is because our providers will adjust the ECMS so that it takes longer to hack, and so the coders cant just use the Euro coders work.

This and my thread below is a compilation of reports from European Sites, professional fta, and research made by Ladybbird, I hope other fta sites that copy and paste this info attribute it to; AAAFTA... simply the best

So it looks like the information I received last year was correct:

This document has been duplicated for this forum:

To help you all understand N3.

In response to the number Of Threads/Post
being made Through Out the DSS/FTA Community
this Thread To help you Understand What N3 is And what You can Expect ..

About Nagra 3

Q. What is Nagra 3?

A. Nagra 3, also referred to as N3 & Nag3 is the newest encryption system being implemented on DN & B3V.

Q. Why is Nagra 3 causing us problems?

A. Because all FTA use on DN & B3V uses an older system, Nagra 2. The coders know Nagra 2 like the back of their hand. Nagra 3 is new and needs to be mastered & broken. DN & B3V are switching things over to Nagra 3.

Q. What is the cardswap?

A. The cardswap is the effort by B3V & DN to switch out the access cards used by subscriber boxes. The cards they are replacing are nagra 2 cards and are being replaced with new Nagra3 cards, also referred to as the ROM240 (B3V), ROM241 (DN). The new DN cards are sometimes referred to as "G3" cards since G3 is on the front of them.

Q. FTA doesn't use cards, why is this affecting us?

A. Because the software used in your FTA box is likely modeled on the older card that uses Nagra 2. The coders have yet to break and understand how the new card using Nagra 3 works. Therefore they cannot write software (the BIN file) to work with Nagra 3 yet.

Q. How long until everything goes Nagra 3?

A. Exact dates are unknown. B3V completed its cardswap awhile back and is testing N3 only channels. Expect it to go completely dark aound the 1st of November if not before. DN has recently started its cardswap and will take significantly longer to complete. DN HD channels could go dark as soon as November sometime as indications are that they are swapping HD customers with N3 cards first.

Q. Will Nagra 3 be hacked?

A. Nothing can be promised but all past and current indicators are that yes, a hack of some sort will eventually surface. Do not expect to see or hear of it until the DN cardswap is complete. It also may or may not require you to use a Nagra 3 card in your FTA. This early on in the game it is educated guesses and speculation.

Q. Some of my B3V channels are missing, or I just have audio. What is wrong?

A. Odds are that those channels are using Nagra 3. Audio on many channels is not encrypted or is still using Nagra 2, that would be why you may have sound on HD channels but no picture. At this point there is nothing that can be done to get it back

Q. will i have to buy another receiver?

No you will not - just wait till after N3 and all info needed will be Posted

How does it work

I have seen a bunch of talk about Nagra 3 being implemented and tested in the data stream so I figured I would explain a bit about how encryption works so that folks understand a bit more about why these rumors are false and why they shouldn’t worry about the release of Nagra 3 so much…..

Just so you know, this is a simplified version… professional encryption is a huge deal with several formulas, algorithms etc….. but just as encryption is huge so is DECRYPTION…… in other words, for every person making encryption there is 5 working to decrypt it…. All of them working for our stb manufacturers….. Here is a basic idea of how encryption works :

All encryption is based on a mathematical formula…. For example… you start off with a code to crack and the idea is that you want to find out how many apples Johnny has in his bucket….. here is how the systems would work…

NAGRA 1….. this works on basic addition (not really.. this is the part where I am makin’ it simpler)…. You start off with someone leaking that there was originally 3 apples in Johnny’s bucket…. The only mathematical process Nagra 1 knows is addition….. so… the provider sends down the number 5 in the data stream… through basic addition your formula tells you to add 5 apples to the original 3… you get eight and boom….. you know the answer…. A simple calculation like this would be done millions and millions of times by your receiver in seconds….. this produces your tv pic using binary language…. When the provider uses addition to change the amount of apples originally in the basket you need a new bin file to help your receiver decrypt the signal….

NAGRA 2…… Now you introduce subtraction into the mix… now the provider can change the number of apples originally in the basket both ways… add more or take some away….. the equation is twice as complicated and your receiver has to work double time…… every once in a while the equation gives you a previous number used because due to subtraction you can go back to a previous number…. This is what happens that causes a previous bin file to work…..

NAGRA 3… Ok… let’s say this bad boy can do multiplication….. now your equations are 3 times as difficult… it is harder for coders to find the formula…. Your number of original apples can now go from 100000 to 2 in a flash of a second due to multiplication…… your receiver is working triple time…… it takes the coders longer to learn how many apples are in the basket……

Bottom line… the bad news is that you may not have any apples in your basket for a while since the coders will need time to figure this out……. The good news is that they are geniuses and a whole lot of rich folks will be losing a pile of money until they get some apples back in your basket……LOL….. no worries….. we will get some downtime but we will be back up and running….

What is N3 and what does it mean?

this is an excellent post by vice




What is N3 and why does it effect the viewing of programming while using fta receivers. In order to understand this myself I did some research online. While this might not be 100% accurate or very technical based, I think it will serve as a rough outline of what N3 is and what we can expect AT THIS TIME.
To really understand this question we must first learn some terminology and background on what is involved in viewing those programs. Let's start out with some definitions.

CAM or conditional access module is defined by the DVB standard as an interface between a standardised DVB common interface receiver and one or more proprietary smartcards for signal decryption. It is not the smartcard itself. The standard format of this module follows PCMCIA specifications; some receivers bypass the requirement for a separate module by providing embedded CAM functionality in the receiver to communicate with specific proprietary smartcards such as Nagravision, Conax, Irdeto, Viaccess, Betacrypt. In the North American market, most "package receivers" sold by signal providers provide embedded CAM operation; terminology is therefore often misused to misidentify the smartcard as a CAM.


CW control words are also some times called Keys. (see explanation below)

DSA. Digital signature algorithm. DSA is based on a different mathematical problem than that of RSA (discrete logarithm problem) or the difficulty of inverting a mathematical exponentiation operation in a finite field. DSA generates a digest of the message to be signed using a hash function as with RSA. The digest is then processed by a DSA signing operation, which requires private key and generates two 160 bit numbers. This signature accompanies the original message when sent. A recipient system that needs to verify the signature recomputes the digest by applying the hash function to the received message.

DES algorithm was initially published as FIPS publication 46 (USA Federal Information Processing Standards ) in 1977. The algorithm is designed to encipher and decipher 64 bit blocks of data using a 56 bit
key.


DVB. Digital Video Broadcasting is a suite of internationally accepted open standards for digital television. DVB standards are maintained by the DVB Project, an international industry consortium with more than 270 members.

ECM (Electronic counter measures) Electronic counter measures are signals that are sent via satellite to to the IRD to combat satellite tv piracy.

EEPROM (also written E2PROM and pronounced e-e-prom or simply e-squared), which stands for Electrically Erasable Programmable Read-Only Memory, is a type of non-volatile memory used in computers and other electronic devices to store small amounts of data that must be saved when power is removed, e.g., calibration tables or device configuration.

EKS. Extreme Key Sharing. This is basically another name for IKS. (see explanation below)

Emulation . is the imitation of behavior of a computer or other electronic system with the help of another type of computer/system

Encryption is the process of transforming information (referred to as plaintext) using an algorithm (called cipher) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. The result of the process is encrypted information

FTA is often used to refer to receivers and equipment which contain no decryption hardware, built with the intention of being able to receive unencrypted free-to-air broadcasts; more properly FTA refers to the unencrypted broadcasts themselves.

Hash functions. A one time function of a data value which is easy to compute but difficult to reverse. The most credible hash function is the U.S. government’s secure hash algorithm (SHA-1). SHA-1 generates a 160 bit output,(with DSA) which gives it a substantial advantage over algorithms with a 128 bit output.

IDEA is a block cipher which uses a 128-bit length key to encrypt successive 64-bit blocks of plaintext. The procedure is quite complicated using subkeys generated from the key to carry out a series of modular arithmetic and XOR operations on segments of the 64-bit plaintext block. The encryption scheme uses a total of fifty-two 16-bit subkeys

IKS. Internet Key Sharing is using a web server to share CW's from a cam or stand alone 3rd party bin file to share the Cw's of encrypted tv programs.

IRD is an integrated receiver-decoder, in other words a complete digital satellite TV or radio receiver; "decoder" in this context refers not to decryption but to the decompression and conversion of MPEG video into displayable format.

KEYS. Keys are a seemingly random string of bits, with the number of bits (key length) depending on the particular cryptosystem. There are private (secret) keys and public keys.

MAP Modular Arithmetic Processor and enhanced DES accelerator are designed to speed up cryptographic calculations using Public Key Algorithms and Secret Key Algorithms.

MPEG-2 (Motion Picture Experts Group technical standard 2) This is a widely used standard for digital encoding of motion pictures. It typically achieves a 50 to 1 compression of data. It achieves this mainly by not retransmitting areas of the screen that have not changed since the previous frame.

RSA. Rivest, Shamir, Adleman. A public key based digital signature scheme. Encryption and decryption has to be applied to the entire message contents and the volume of data is at least double the original message size. To improve the scheme a hash function is introduced into the processing.

Smart card. A tiny processor and storage system realized in a microcircuit embedded in a plastic card.

There are some brief definitions to help us understand things a little better as we get into what N3 is. N3 stands for Nagravision3. This is a form of encryption produced by a company called the Kudelski Group. This is a company owned and operated by Andre Kudelski, based in Cheseaux, Switzerland. The Kudelski Group specialize in security and access control solutions for digital television for many companies around the world. The Kudelski Group forms partnership with companies Like Echostar to provide security and encryption services for Echostar's pay per view programming service they offer. The Kudelski group and Echostar formed a company to offer this support by the name of Nagrastar. Nagrastar is responsible for the security of the encoded broadcasts of the American satellite tv provider Echostar and the Canadian satellite tv provider **** *********. Nagravision is the type of encryption and Nagrastar manage how this encryption is used. Nagrastar does this by the use of smart cards or built in Cams in some of the newer models of IRD. They update these Cams by sending a ECM to update the EEPROM in the smart card or cam installed in the IRDs. This ensures only authorized or paying customers are the only ones who can view their encrypted programming. To explain in simple/basic terms, what this means is Nagrastar will encrypt the signal at their uplink center using the present form of nagravision encryption. Echostar uses an uplink center which is based in Cheyenne , WY, USA to compress their signal into the Mpeg2 and Mpeg4 format and add the encryption . **** *********'s uplink center is located in North York which is in the Toronto, Ontario, Canada.
When Direct tv secured their signal with the introduction of the P4 card, satellite tv hackers moved on to the weaker encryption used by Echostar and **** *********. At that time it was Nagravision1 encryption being used to secure the signal broadcast from the satellites. Hackers got help in decrypting the N1 cards by Europeans who already were heavy into researching weaknesses in the N1 cards. Also at this same time someone figured out that you could use an FTA receiver to decrypt the programming by loading 3rd party software onto the fta receiver to emulate the smart cards used in the pay for view providers IRD's. After numerous ECM's sent out by Nagrastar, failed to stop hackers from getting access to the programming, it was concluded that a new card would be needed to fully secure the stream. So in the spring of 2005 nagrastar started to change to the Nagravision2 encryption. However once again with help from overseas hackers, N2 was defended almost as soon as the signal was secured. After several more attempts with ECM's, one of which was quite successful for awhile (MAP57) it was concluded that another card swap was necessary in order to once again secure the signal.
This brings us to this point in time. I'm sure many of you are wondering why it is so hard to crack N3 when N1 and N2 seemed quite easy to crack. Well the answer is quite simple. The Nagravision people have had a few years experience dealing with hackers and in fact have hired some of the former hackers to help them secure their signal from any future breaks in the encryption. They have done this by building better firewalls and increasing the complexity of the algorithms used to encrypt the signal broadcast by the pay per view providers. They do this by using a combination of RSA, IDEA, DSA, DES, algorithms. This makes it next to impossible to guess what the CW's are because the possible output combination of these Algorithms equal more then all the molecules in the universe. So hackers must get inside the card to see what exact is going on and how the card/cam is using the MAPs to process the CW's. Now this is not easy to do. They do it by a complex method of using acids to peel the layers off the chip and sending electrical currents to the chip to see how it reacts. This is a science mastered by very few hackers/card crackers in the world. N3 has been in use in Europe for at least a year now and no one has a successful hack for a free standing hack of the N3 encryption. Remember Europeans are the ones who helped crack N1 and N2.

Now what does this mean for people using FTA receivers at this time. Well it is obvious to anyone who was using a FTA receiver to view the programming of **** *********, it means a black screen. OH no, you cry, what will I do. Well you have several opinions. You could start paying the providers to watch tv. It's expensive, has allot of crappy stations but it never goes down. Next you could do true FTA. After all you already have a FTA receiver and cables run. You would only need to switch to a larger dish and linear lnb. This is minimum cost and you get quite a few channels such as fox, abc, cbs, etc. However what you don't get is, HBO, PPV or porn. Let's face it, this is what most FTA receiver or card hackers want to view. So what does that leave you with? Well I'm afraid it's Card sharing, IKS or EKS. The Nfusion was the first FTA to be successful on a large scale in North America. However even these will not give you wide open tv. You can only view what you buy as a package for the providers. A basic explanation of how IKS or at least how I think works (because I'm not a hacker but a student/studier of satellite tv), is like this. A group buys a sub or combination of subs and sends all the CW's for ALL the channels to a central server where the CW's are cache until a request comes in to the server requesting the information for a certain channel. A fta receiver is connected to the internet, 24/7. As you choose a channel to watch on your tv, the receiver sends an encrypted packet to the central server with the receiver's ID and CW request for that channel. The server reads this packet of data and sends back the CW's needed to view that programming.

Cool you say. Well this method has it's pit falls as well. For example, decrypting the encrypted programming of the pay per view providers is considered illegal in North America. This could lead to a fine from a civil lawsuit by the providers or even a criminal charges by the legal authorizes in your area. If a person was to use this method they should take steps to hide their true identity because despite what these salesmen will tell you, your IP can be traced. If your receiver makes contact enough to process the data packet requested by the receiver then there is a trail to your house. No country is safe from a server seizure either. Even Hong Kong as turned over servers to Echostar when they got sued to get possession of those servers hosting hacking files by Echostar. How do you stop from getting caught?? Well some use a proxy. However not all proxies are created equal. Some proxies are transparent and can be seen right through. IKS has a hard time process CW's using good proxies because of the time delay in the request data packet. My PERSONAL opinion is it's not worth the risk. However now that you have the facts you can make up your own mind as to what you want to do as N3 nears completion and all channels go black.

I'm hoping many of you try TRUE fta and become hobbyist at this fta stuff. I think you will find it is educational and fun to cope with.

that is correct , so in a simple factor it's a matter of time before the new file system is decrypted and hacked to our benefits ( to make a long story short ) .

[louisperry]

Thanks for the info. Was clarifying to me.

[HDGAL]

To be even more simple....(that's just me...lol) if man (or woman) can create a code, man (or woman) can crack that code. I'm very optimistic about N3 and in my opinion, we will see a fix for both providers shortly after DN is finished swapping.

I agree Gal, the rumour is getting stronger that Viewsat has cracked it. If so Ive won the bet!!!!

[Ladybbird]

Bump for those still asking.

[Ladybbird]

Here is more info vlytly

[Zombie]

This info should be updated as N3 has already been cracked and they are just waiting on DN to go down.
