Research on Data Encryption Technology Based on Chaos Theory

Data encryption is one of the active strategy of information security, which can provide strong protection. A chaos dynamic logistic model was chosen as the data encryption algorithm in this paper, then randomness, correlation, complexity of logistic chaotic series were verified through power spectrum, Lyapunov exponent mathematical analysis and it meets the needs of cryptology. Meanwhile, in theory and experiment, we know this algorithm has high security and robustness, it can resist differential analysis and linearity cypher analysis.
