摘要 提出了一种基于混沌映射和乘同余法构建单向散列函数的算法.该算法通过乘同余法生成伪随机序列作为系统的初始值,把明文信息的美国标准信息交换码(ASCⅡ码)归一化后作为混沌映射的初始值,经过可变步长的混沌数字量化后,提取出128 bit的散列值.理论分析和仿真结果表明:该算法具有较好的不可逆性、抗碰撞性、防伪造性、初值敏感性以及较高地运行速度. A one-way hash function algorithm is proposed based on the chaos mapping and multiplicative congruential method. The initial value of the system is generated by the pseudo-random sequence which is obtained through the multiplicative congruential method, the normalized ASCII of the plaintext is used as the initial value of the chaos mapping. After a variable-step chaotic digital quantification, 128 bit hash value is extracted from the systems. Theoretical analysis and simulation results show that the proposed method has better characteristics of irreversibility, collision resistance, anti-forgery, initial sensitivity and higher operation speed.
