| 摘 要： | 信任测度是信任机制的核心和基础,现有的信任机制面临着恶意用户操纵信誉的安全威胁。基于用户及其行为社会属性的信任测度模型对传统的信任机制进行了扩充,引入用户及其行为所映射的本质特性即社会属性来描述和分析恶意用户及其行为的特征,在信任测度过程中增加信誉评审过程来修正对信任测度的攻击,从而保证了分布式环境中的信任测度的可信性。模拟实验表明,该信任测度模型能有效地应对恶意用户对信誉的操纵攻击。

| Abstract: | Trust measure is the basis of trust mechanism. Now the trust mechanism is facing the threat that malicious users manipulate the reputation. I}he trust measure model based on the social factors of users and their behavior expands the traditional trust mechanism. It describes and analyses the characters of malicious users and their behavior by the social factor,which reflects the essential of user and behavior. This model also adds the audit process in order to correct the reputation under the attack, so it can guarantee the credibility of trust measure in distributed Environment. Simulation experiments show that this model can effectively react to the reputation manipulation attack by the malicious users. |
