摘　　要：为解决现存密钥分配方案中计算复杂、效率低的问题,提出了一种基于时空混沌同步的同步密钥生成算法.该算法能使通信双方同步产生相同的任意长度的密钥,实现了"一次一密"的会话密钥.经过分析及实验测试,该算法满足安全性要求,并能产生高质量的密钥序列.To solve the problem of computational complexity and low efficiency of the existing key distribution scheme, a synchronized key generation algorithm based on spatiotemporal chaos synchronization was proposed. Using this algorithm both side of the communication can synchronously produce the same keys of any length, it truly implements the ＂on-time pad ＂ session key. The analysis and tests show that the algorithm can satisfy the security requirements and produce high-quality key sequences.
