Research on Performance of Coupled Tent Map Lattices System

摘要

Coupled Tent Map Lattices system (CML) has made a good combination between confusion and diffusion, which can be well adopted in the design for Hash function and sequential cipher and possesses high value in cryptographic application. Whereas, Coupled Tent Map Lattices system parameters cast a direct influence on cryptographic performance. This paper chooses tent map as the non-linear function of coupled map lattices and conducted a detailed analysis of the influence of system parameter changes on random feature, differential distribution feature, invariant distribution feature, complexity, Lyapunov exponent, balance of the sequence generated by CML, to serve as a reference for cryptographic system design.
