CHAOTIC ENCRYPTION BASED ON LORENZ SYSTEM

Abstract

Compared with the low dimension chaotic systems (LDCS), the high dimension chaotic systems (HDCS) have many advantages as more complex mechanism, increasing the key space, more ruleless for the time series of the system variable, etc. Based on these reasons, a new encryption cryptosystem based on Lorenz system is proposed. The theoretical and experimental results show that, this algorithm can resist the local linear attack, the phase space reconstruct attack, the entropy attack, etc. The proposed cryptosystem has higher security.
