摘　　要：为了提升密钥信息分发速率,解决身份认证错误的问题,提出基于复合混沌序列的身份认证密钥分发建模方法。根据复合混沌序列表达式,确定补偿系数指标的取值范围。根据Walsh协议文本完成基于复合混沌序列的身份认证。通过求解密钥生成率、分发距离与信息消耗速率,以此实现身份认证文本密钥的分发与建模处理。实验结果表明,遵循复合混沌序列表达式所建立的密钥分发模型可以将身份认证有效性提升至93%,能够大幅度提升密钥信息分发速率,解决了身份认证错误的问题。In order to improve the distribution rate of key information and solve the problem of identity authentication error,a modeling method of identity authentication key distribution based on composite chaotic sequence is proposed.According to the expression of complex chaotic sequence,the value range of compensation coefficient index is determined.According to the Walsh protocol text,the identity auth-entication based on the composite chaotic sequence is completed.By solving the key generation rate,the distribution distance and the information consumption rate,the distribution and modeling of the authentication text key are realized.The experimental results show that the key distribution model established by following the expression of complex chaotic sequence can improve the validity of identity authentication to 93%,greatly improve the key information distribution rate,and solve the problem of identity authentication error.
