摘　　要：提出一种基于混沌理论的字符串加密算法。通过应用混沌理论的"随机过程"产生随机密钥和随机干扰字符串,使用密钥对明文字符串进行异或(XOR)加密,再将运算后的密文同密钥、干扰字符串按照一定规则组合构成完整的混沌密文。该算法具有运算量小、灵活性强、加密强度高的特点。The paper presents a string encryption algorithm based on chaos theory.By applying chaos theory＇s ＂random process＂,the random key and random interference string are generated.The encryption key encodes plaintext strings with XOR operation;then composes the computed encryption text with the encryption key and interference string together according to designated rules to build a complete chaos encryption text.The algorithm bears such features as fewer calculations,greater flexibilities and stronger encryption.
