摘    要:为克服传统网络身份认证方法安全性不高、效率低等不足,受人类自然信任原理启发,提出了一种基于家族基因的身份认证模型(FBNA).给出了模型中网络家族、家族成员及成员基因等定义,建立了基因指派、基因签名等仿生机制,描述了网络家族构造、基因证书生成,以及基于家族基因的身份认证等算法.解决了静态口令认证安全性差、动态口令认证复杂等问题,同时克服了数字证书认证计算量大、证书主体信息不明确等缺陷.理论分析和实验结果表明该方法是鉴别网络实体身份的一种有效新途径.

关 键 词:网络安全  身份认证  人工免疫  家族基因

Abstract:Inspired by the natural trust principle of mankind,a family-gene based model for network authentication,referred to as FBNA,is proposed.The concepts and formal definitions of network-family,family-member,family-gene,and aberrance-gene of the model are presented.Then the bionic mechanisms of gene-assignment and gene-signature are built,and the algorithms of network-family construction and gene-certificate generation are described.Finally,the identity of users and network devices are authenticated through analyzing their gene codes.By using FBNA,the deficiencies of the traditional authentication techniques,such as inferior safety of passwords,high communication traffic of PKI,and ambiguity of X.509 certificates are overcome to a certain degree.Our theoretical analysis and simulation results show that the proposed method is an efficient novel solution to network authentication.
