this is for coders pleas releas sum sort of bin even if it is without (example ppv) or (hbo showtimes stars exetra exetra) as long as we have some sort of tv we will be thankfull
puertorican, yf dey new hou to fix de bin, dey ood doo it. But dey dont no! I too wood like dem to fix de goo shannels. Dey shood do sonsing abaut dis blakout!
Kudelski and Echostar have recently updated their smart cards in order to thwart piracy. Here is what they did:
1. They introduced two new methods of decrypting the video keys, namely,the $40 M*** method and the $60 M*** method. They now have the ability to use either or both methods. Both of these methods use onboard MAP functions to properly decrypt the video keys. 2. They introduced code that prevents glitching into their cards. Rev109 and Rev245 cards can no longer be unlocked. 3. The latest revisions also have new code that will disable the use of the MAP functions if smart card tampering is detected. This feature is not being used yet, but probably will be very soon.
In order to really appreciate what is going on, you need to understand what a MAP function is. MAP stands for "Modular Arithmetic Processor".The smart card consists of one main CPU and several additional onboard processors that assist the CPU with certain tasks. One of these tasks is cryptography and the MAP processor implements all the encryption routines like DES, RSA, IDEA, SHA, AES, etc. When the main CPU wants to perform a math function like those listed before, it calls the MAP processor, gives it some input and expects some output in return. Without the actual circuit design and source code for the MAP processor,it is impossible to know exactly how each function works. We can't dump the MAP functions because of hardware firwewalls. The best we can do is guess how each function works! Don't laugh! So far, guessing has worked well for us. For example, we dicovered the IDEA and RSA MAP functions which enabled us to decrypt the video keys up until a few weeks ago. How did we do that? Well, we guessed and got lucky! No, seriously, Nagra has a bad habit of implementing well known mathematical functions without making any changes. So we just guess and get lucky. The guesses are based on key lengths, message lengths, etc. But now Nagra has started using MAP functions that aren't so easy to guess. Even if these MAP functions are discovered by luck, they will just introduce new ones. They are doing all this to stop the proliferation of FTA boxes. Make no mistake about it, the proliferation of FTA boxes posed a SERIOUS threat to their business. They had to stop this and they did it by introducing some new MAP functions. In the process they not only took out the FTA boxes but everything else too. Only ROM102/103 cards are working at the moment. But those hacks won't last very long either. Nagra intends to permanently disable those cards not by looping them, but rather, by disabling the fuse bits that allow the MAP functions to work properly. The code to do this is already in place. Things are not looking so good for testers, but they have never looked better for Nagra. Looks like the only thing that will work in the future will be card sharing over the internet or AUX-ed card and emulation. If you don't believe it, well, the Europeans have been down for several months now because of the use of new MAP calls and many have turned to card sharing. Now, I wonder how Kudelski and gang will handle card sharing.
"When the main CPU wants to perform a math, it calls the MAP processor, gives it input and expects output"
MAPPING calls makes this like a firewall. Firewalls are made to prevent intrusion. Hence. game over.
Coders can't guess the complexity of the microprocessor's gate structure in these areas and their interaction. Only the manufacturer of the card knows. Reading the "Art of Assembly" found on the net will give you a better understanding.
It has gone the way of Dave... same idea. No more fix. Game Over.
Sorry to agree with bearer of bad news but this is the case now, no more fixes, no use burying your head in sand with wishing optimism, it will just not happen this time. Again, game over.
I agree that it is more complex, but don't underestemate any coder out there, they are coders, not quitters, it is possible to get threw this, any firewall has it's weak spot, I beleive in time they will find this weak point, and get in and then we are back in business, but you have to let the system run it's course before you can figure it out, it's gotaa run to be done
bin chi code. your showing off. Puerto do you really think coders are reading this. Please. maybe they are and thats why the bin is still not out because there in here chatting with us. Ozz, are there any brains left?
Coders still working on the fix, the manufacture for FTA receivers have a full warehouse of then, and they are going to comeup with a fix, but for how long is going to last is anothe story? All we can do is wait and see. Alien
