基于混沌理论和单向散列函数的性质，提出了用类Hènon 混沌映射构造单向散列函数的算法，并讨论了此算法的安全性。这种算法具有初值敏感性和不可逆性，且对任意长度的原始消息可生成256 位的单向散列值。用该算法可以很容易的求出所给明文消息的摘要，然后生成数字签名。关键词 混沌；单向散列函数；类Hènon 映射；数字签名[Abstract] Based on chaotic theory and one-way hash function character, it is presented toconstruct a one-way hash function algorithm with Hènon-like mapping and discussed security of algorithm. It is sensitive to initial conditions and irreversible, we can produce 256 bits one-way Hash for the initial information. Message digest of the plaintext can be produced easily and then to produce digital signature.[Key words] Chaos；One- way Hash function；Hènon-like mapping; Digital signature.
