Information-Theoretical Analysis of Two Shannon's Ciphers

Boris Ryabko

Abstract

We describe generalized running key ciphers and apply them for analysis of two Shannon's methods. In particular, we suggest some estimation of the cipher equivocation and the probability of correct deciphering without key.
