OK, I hopped as your signature contains an key team it meaned something else as it was already reported that the 01 key was missing (like a key server specifically for enigma2 cable receiver).
Anyway thank for answering me.
From a mathematical point of view I don't understand how one find a new key ?
Shall one record a ts and try all 01 kex to see if one magically works ?
After all if I count right there is "only" 256^16=3.4*10^38 possibilities... so if a big computer can try 1000 keys per second without luck we could have the "right" one in about 10^28 years...
Could anyone share some lights on a better way to find keys to decrypt channels ?
Is there somewhere the decrypt alorithm for nagra to be found ?
Thanks and have a great day, even without the key 01 !!!
