摘要
为增强信息的保密性,指出了具有误导功能的低冗余加密算法存在的安全问题,在此基础上进行了算法改进,提出了一种基于Hash函数抗软磨硬泡攻击算法,通过对扩充项和密钥的处理,在不增加算法冗余的情况下增加算法的安全性。由实验验证和结果分析可知,改进后的算法大幅度提高了原有算法的复杂度、安全性和可靠性,通过对密钥的保护处理,使得密钥的存储更加安全可靠。
In order to promote the confidentiality of information,the study points out the security problems of low redundancy encryption algorithm qualified with misleading function.Based on this,the algorithm is improved,and the rubber-hose attack algorithm based on Hash function.Through the processing of expansion and secret key,the confidentiality of the algorithm will be increased through the continuous increase of algorithm redundancy.Through the experiment verification and result analysis,the improved algorithm greatly improves the complexity,security and reliability of the original algorithm.
