摘要
多源异构数据体量呈指数级别增加,数据时序混乱,为此提出基于混沌系统的扩频通信多源异构数据加密算法研究。引入混沌系统,利用Logistic混沌映射多源异构数据,以混沌映射轨迹点为基础,生成多源异构数据混沌序列,通过Merlay状态机控制数据时序,提供子密钥产生信号,以时序控制信号为依据,利用特定阀值函数产生子密钥,采用子密钥对多源异构数据进行正向、反向异或以及取模,实现扩频通信多源异构数据的加密。测试结果表明,密钥相差+10-13无法解密出正确数据;加密后图像、音频数据相关性急剧下降;加密时间范围为16.451 s~18.630 s,低于最高限值。测试结论:密钥敏感性、抗统计特性以及加密效率较好,适合大力推广应用。
The amount of multi-source heterogeneous data increases exponentially,and the data time series are chaotic.Therefore,a chaos system based encryption algorithm research for multi-source heterogeneous data in spread spectrum communication is proposed.The chaotic system is introduced,the multi-source heterogeneous data is mapped by using logistic chaos,and the chaotic mapping track points of multi-source heterogeneous data are on the basis.The data chaotic sequence of multi-source heterogeneous data is generated,and the data sequence is controlled by the merlay state machine to provide the sub key generation signal.The sub key is generated by using the specific threshold function based on the time sequence control signal,and the sub key is used to forward and reverse the multi-source heterogeneous data XOR and to make mode selection,the encryption of multi-source heterogeneous data in spread spectrum communication is realized.The test results show that the key difference+10-13 can not decrypt the correct data;after encryption,the correlation between image and audio data drops sharply;the encryption time range is 16.451 s~18.630 s,which is lower than the maximum limit.Test conclusion:the key sensitivity,anti statistical characteristics and encryption efficiency are good,and it is suitable to promote the wide application.
