This work addresses cryptographic security analysis for encryption systems, but appears incremental as it builds on established Shannon methods.
The authors analyzed two of Shannon's ciphers by applying generalized running key ciphers, focusing on estimating cipher equivocation and the probability of correct deciphering without a key.
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.
