A Fast Chaotic Data Encryption Algorithm Based On Chebyshev Map
Chaos theory provides a new approach to stream cipher technology and the quantified chaotic binary sequence has great influence on the efficiency and security of an encryption system. In this paper, an improved stochastic middle multi-bits quantification algorithm based on Chebyshev map is proposed to improve the efficiency and enhance the securiAcondition. The balance and correlation properties of the quantified chaotic binary sequence are analyzed. The sequence is proved to be a binary Bernoulli stochastic sequence and the distribution of the differences between the amounts of 0 and 1 is analyzed. The side lobes of auto and cross correlation are proved to obey normal distribution N(0, 1/N). The experimental results indicate that the algorithm ts more efficient and secure than other algorithms.
