An Encryption Algorithm of Chaos Based on Sine Square Mapping

摘要：

The paper applies chaotic encryption to information document, and designed a simple and fast encryption algorithm based on Sine Square Mapping. This kind of mapping can be chaotic in a wide parameter range and the sequences generated possess larger Lyapunov exponent and excellent dynamical properties. The keys of systems parameters, initial value and iterations are selected in order to let the chaotic encryption algorithm has a higher security and increase the key space. The simulation results show that the encryption algorithm of this paper can effectively resist the common assault of chaotic systems——statistical attack and brute-force attack.
