摘要：

A data encryption approach to chaos synchronization communications by using a novel chaos-based pseudo-random number generator (CPRNG) is proposed. Chaotic sequence generated by the drive system is turned into encryption keys in CPRNG and the data can be alternately encrypted according to byte by using the keys. The advantages of the cryptosystem are its higher level of security and synchronization, and it is easily implemented by software.
