Any body knows mathematical model for cracking the comp128?
In simscan readmy written:
New method can find 16 bytes Ki in next steps:
1) 2-R attack for getting first 2 bytes of Ki and take approx. 16000 cipher texts
2) 3-R attack for getting next 2 bytes of Ki and take approx. 758 cipher texts
3) 4-R attack for getting next 4 bytes of Ki and take approx. 758 cipher texts
4) 5-R attack for getting last 8 bytes of Ki and take approx. 832 cipher texts
the 2-R attack understandble ....
But how,3-R,4-R,5-R working?
