基于家族基因的网格信任模型

针对现有基于PKI (Public Key Infrastructure)的网格信任系统的不足，证书主体信息不明确, 认证过程复杂等缺陷提出了一种新颖的基于家族基因的网格信任模型。该模型解决了传统信任模型存在的问题，如采用将用户的全部身份信息放在用户的基因里方法解决了证书主体信息的不明确，用基因检测解决了认证过程的复杂，用基因指派解决了访问控制的繁琐，并且给出了网格家族、家族基因、基因指派、基因鉴别和信任等概念，并建立了模型的形式化描述，理论分析和实验结果表明这种模型是网格信任领域一种较好的解决方案。

Grid Trust Model Based on Family Gene

In the light of the deficiencies of current grid trust models based on PKI (Public Key Infrastructure), such as ambiguity certificate information and complicated identification process,a novel grid trust model based on Family Gene (FG) model was proposed. The model solves the problems existing in tradition trust models. For example, we adopt the technology of the whole sequences of information required by a user to address the ambiguity certificate information, gene identification to solve the complexity of authentication process, and gene assignment to address the complexity of visit and control. The concepts and formal definitions of grid family, family gene, gene assignment, gene identification and trust in the grid trust security domains were given. Then, the mathematical models were established. The theoretical analysis and experimental results showed that the model is a good solution to grid trust domain.
