Structure of Frequency Hopping Sequences Family Based on Stream Cipher

跳频序列的性能对跳频通信系统性能有着决定性的影响.本文基于密码学的流密码加密机制,提出构造一种跳频序列簇的方法.文中以蓝牙技术采用的E0流加密算法为例,对输出的二进制加密流进行多位组合构成跳频序列的频隙号.并在此基础上对产生的跳频序列从安全性,均匀性,线性复杂度,汉明相关性等各个方面进行了全面的理论分析和计算机仿真,证明基于流密码算法产生的跳频序列族有着优秀的性能,完全满足跳频序列簇的要求.

The performance of frequency hopping(FH)communication system is fateful affected by FH sequence.A family of FH sequences based on stream cipher is proposed for FH communication.Given an illustration of E0 stream cipher algorithm,the FH slot numbers are composed by the output binary stream of E0.Simulation and analysis results show that the proposed FH sequences based on stream cipher have good performance in security,uniformity,correlation,complexity etc.,and agree well with the demand of the FH sequences.
