提出了一种利用新型的基于混沌的伪随机数发生器(CPRNG)系统实现的数据加密通信方案.在该方案中，发、收两端的CPRNG系统将驱动系统产生的混沌序列转换为加密密钥序列，利用这些密钥序列对明文数据按字节切换交替加密. 系统的主要优点是在通信的安全性和同步性上有所改善，且便于用软件实现.

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.
