NDS Research
From Hax0rpedia
I did some research on the NDS Videoguard Cipher protection and came to the conclusion it is kinda secure, unless, someone would be able to get the algorithm of the card and catch the EMM with infos for the update and decrypt them.
The algo used on the card seems to end up in a md5 sum which is used as a key, hw it exactly works, well, thats the question of all.
Interesting read, and only value resource I found so far is: http://colibri.de.ms/
He seems like the only lonesome cowboy these days, bothering to publish some kind of this stuff in such a quality form. Stay away from PayTV pirate boards. Most forums are flooded with nobish freaks, who only interest is getting free PayTV, but where is the fun? Once it works, it's uninteresting anyhow.
Current methoods involved to get around this still secure technique is something people call cardsharing, which means sharing the keys calculated from the card via some kind of private p2p darknet. Tools used for this is a further development of card2d called card3d which has this functionality.
To dump EMM and EMC packets from PayTv, use a dbox2 or similar and card2d you get from your linux. Source for it is available from tuxlinux site (check out the cvs trunk, you will find it).
I will continue this file on my list once my new dbox2 arrives so I can dump a bit.
