Реферат:	eng: In 1949 Shannon published the famous paper "Communication theory of secrecy systems" where he briefly described two ciphers, but did not investigate their properties. In this note we carry out information-theoretical analysis of these ciphers. In particular, we propose estimations of the cipher equivocation and the probability of correct deciphering without key.
