| Abstract: | This paper presents the probability model of the control-choice cryptographic logic. A necessery and sufficient condition is gained which satisfies that the mutual information is zero between control and output sequences of the control-choice cryptographic logic. By using the information leak between control and output sequences, a method of analysing the control-choice cryptographic logic is given. |
