摘要
针对传统Cascade算法协商效率低、吞吐量不高的问题,提出了一种面向共驱混沌同步密钥分发的Cascade-Biconf信息协商算法。该算法基于奇偶校验和二分法纠错算法的原理,将所得密钥进行置乱、分块并传输校验值用以二分法纠错。与传统Cascade算法不同,Cascade-Biconf信息协商算法通过优化分块的大小降低了协商过程中的交互次数和计算量。仿真结果表明:在通信双方初始密钥误码率为0.1的情况下,Cascade-Biconf信息协商算法可将传统Cascade算法的协商效率由0.76提升到0.84,总吞吐量提升27.9%。
Aiming at the problem of low negotiation efficiency and throughput of traditional Cascade algorithm,a Cascade-Biconf information negotiation algorithm for codrive chaotic synchronous key distribution is proposed.Based on the principle of parity check and dichotomous error correction algorithm,the obtained key is scrambled,divided into blocks,and the check value is transmitted for dichotomous error correction.Different from the traditional Cascade algorithm,the Cascade-Biconf information negotiation algorithm reduces the interaction times and computation amount in the negotiation process by optimizing the block size.The simulation results show that when the initial bit error rate of the two communication parties is 0.1,the Cascade-Biconf information negotiation algorithm can increase the negotiation efficiency of the traditional Cascade algorithm from 0.76 to 0.84,and the total throughput can be increased by 27.9%.
