提出了一种基于变参数混沌映射的单向哈希函数构造算法。选择参数P可变的分段线性混沌映射，并引入密码块链模式（CBC），保证每次迭代中的参数P由上一次迭代值和不同位置对应的消息位动态决定。最终的哈希值是通过对迭代序列进行线性变换得到的。理论分析和计算机仿真表明，该算法能够高效、灵活地满足哈希函数的所有性能要求。它实用可靠，在电子商务中应用的潜力很大。
An algorithm for one-way Hash function construction based on the chaotic map with changeable-parameter is proposed in this paper. A piecewise linear chaotic map with changeable-parameter P is chosen, and cipher block chaining mode (CBC) is introduced to ensure that the parameter P in each iteration is dynamically decided by the last-time iteration value and the corresponding message bit in different positions. The final Hash value is obtained by means of the linear transform on the iteration sequence. Theoretical analysis and computer simulation indicate that our algorithm can satisfy all the performance requirements of Hash function in an efficient and flexible manner. It is practicable and reliable, with high potential to be adopted for E-commerce.
