In this paper we study the structures and properties of a single cycle T-¯nction, whose theory has been lately proposed by Klimov and Shamir. Any cryptographic system based on T- functions may be insecure. Some of the TSC-series stream ciphers have been successfully attacked by some attacks. So it is important to analyze every aspect of a single cycle T-function. We study some properties on a single cycle T-function and we show some examples are single cycle T-functions by these properties, whose proof is easier than existing methods.
