| 摘 要： | 类似人际网络,网格中实体间的交互会留下相应的交互行为记录,即用于网格信任管理中行为信任评估的证据.为了保证网格中实体间互操作的交易信息安全,提出了一个实现信息隐蔽性的匿名存储模型.利用Hash函数以及非对称双重加密技术实现了实体身份与交互信息的匿名性,并设计了随机转移算法实现信息在网格系统中的匿名存储,基于伸展树结构的匿名查询实现了信息的高效检索和更新操作.模型可以有效地防止网格中的恶意实体出于报复或其它目的对交易信息的攻击和篡改,通过模型性能分析和仿真,该模型具有实用,安全,高效的特点.

| Abstract: | Like Interpersonal,the interaction of entities in grid will generate corresponding interactive information which will be used as evidence data for the assessment of trust management.This paper presents an anonymous storage model to ensure trade information of entities in grid.This model is based on Hash function,unsymmetrical encrpytion techniques,and the paper designs a stochastic transfer arithmetic to achieve anonymous storage.Based on the splay tree structure the information could be searched and update... |
