摘　　要：针对当前算法对电力线载波频谱进行分组量子加密时,存在加密效果差、加密的雪崩效应性能低以及安全性能差的问题,提出了基于Logistic混沌的电力线载波频谱分组量子加密算法.通过电力线载波频谱参数分析构建Logistic混沌模型,以此为基础迭代求解量子加密密钥,并在量子极化的原则下分配密钥,在信道中生成可分配的筛选密钥,并利用POVM算法分配密钥,实现电力线载波频谱的分组量子加密.实验结果表明,所提算法的加密效果更好、加密的雪崩效应性能更高以及安全性能更好.Aiming at the problems,such as poor encryption effect,low performance of avalanche effect and poor security performance when using the current algorithm to encrypt the power line carrier spectrum,a grouped quantum encryption algorithm based on logistic chaos for power line carrier spectrum was proposed.The Logistic chaotic model was constructed through the analysis of power line carrier spectrum parameters.On this basis,the quantum encryption key was iteratively solved,the key was distributed under the principle of quantum polarization,the distributable screening key was generated in the channel,and the key was distributed by POVM algorithm to realize grouped quantum encryption of power line carrier spectrum.Experimental results show that the as-proposed algorithm has better encryption effect,higher avalanche effect performance and better security performance.
