Abstract(in English) | This paper discusses the keys on RC4 which parts of them can be recovered from their outputs with high probability. We show parts of initial states can be recovered from their outputs with high probability than the probability that parts of internal state are recovered, and specified RC4 keys generate that kind of initial states with high probability. Exploiting those keys, cryptanalysts can reduce RC4 key space than exploiting Roos's weak key. |
