基于混沌消息扩展的Hash函数
Hash function based on chaotic message expansion
摘要
Abstract
A new Hash function based on chaotic message expansion is constructed, in which message weight matrix is integrated into the spatiotemporal chaotic system, the connection between each character of one message block is strength-ened, and the connection between each message block is also strengthened, the extended message has good statistical properties. A 160 bit message digest is gotten after 4 rounds with 64 steps iteration. Compared with SHA-1 algorithm, the security is improved under the premise that the operation efficiency does not affected too much.关键词
