User Anonymous Password Cross-domain Authentication Method Based on Block Chain Technology

用户匿名口令跨域认证过程中,口令加密编码完整性差,导致认证难度加大,为解决该问题,提出基于区块链技术的用户匿名口令跨域认证方法。构建用户匿名口令的加密密钥,采用算术编码模型构建密钥编码协议,构建口令跨域编码完整性认证的区块链分布模型,结合空间分块加密重组方法进行用户匿名口令加密存储和跨域融合。建立口令跨域认证编码和解码密钥,在线性均匀的区块链结构中进行口令编码控制和跨域认证。仿真结果表明,采用该方法进行用户匿名口令跨域认证的输出安全性较高,抗攻击能力较强,认证时间短。

In the process of cross domain authentication of user anonymous password,the integrity of password encryption code is poor,which makes authentication more difficult.To solve this problem,a cross domain authen⁃tication method of user anonymous password based on blockchain technology is proposed.The encryption key of user anonymous password is constructed,the key coding protocol is constructed by arithmetic coding model,the block chain distribution model of password cross domain coding integrity authentication is constructed,and the encryption storage and cross domain fusion of user anonymous password are carried out by combining the space block encryption and reorganization method.The password cross domain authentication coding and decoding keys are established,and the password coding control and cross domain authentication are carried out in the lin⁃ear and uniform block chain structure.The simulation results show that the output security of cross domain au⁃thentication is high,the anti attack ability is strong,and the authentication time is short.
