the process is very real and correct. the issue is that time is still required to brute force the actual key hence why the source was written for the nvidia cards with the numerous cores to speed this up to an extent. the process works by examine specific parts of the streamed packets with can only have approx 16777216 different values. look these up in the rainbow tables shows u possible key values which when a+b+c&chsum e+f+g&chsum = 8 byte control word
the weakness is in the CSA word lengths and the packet structure organisation which is pretty static.
colibre had some info on this and even had the rainbow tables listed on his site when i last looked some time since.
i reckon 6-10 hours for correct BISS key :O
best regards

Thanks for that. Really good information and well explained.
So has some super smart person not got some programme which can take the NDS keys, review these ans look for a common pattern? I'm assuming that over time someone would be able to produce something which can keep up with the changes via some auto update server?Comment

I Think that if NDS Videoguard used this same system, security would of been compromised years ago. I would say that there is no common pattern in use with Videoguard, and the key(s) generated by the NDS server are completely random. Will someone correct me if I am wrong ...Thanks for that. Really good information and well explained.
