The detail is clarified as follows : l ) based on the chaotic technology and contemporary encryption approach the paper put forward a new chaotic sequence, which introduced the m - sequence and the method of shrink key - the stream generator. the complexity of the sequence was promoted as the random alteration of the parameters of chaotic mapping, and at the same time, the shrinking key was used to enhance the security further more ; 2 ) the performance of one - way hash function was improved and new hash function construction methods are proposed through a novel hash method based on chaotic mapping and the aes - the rijndael algorithm. the algorithm of hashing messages of arbitrary length into 256 bits hash values was designed
按照這種方法，輸出序列的周期性得以大大提高，理論分析和計算機模擬結果表明，該方法可以產生具有良好統計特性的密鑰流，而且易於軟硬體實現： 2 ）實現了一種基於混沌映射和分組密碼rijndael演算法的單向hash函數的構造方法，即使用logistic混沌映射產生混沌二值序列，序列的分組與明文序列分組進行按位異或后，進入rijndael加密模塊，所得的結果再加入到反饋端，參與下一分組輸入的異或運算，迭代結束時的rijndael加密結果即為所求的hash函數值。 -
