GBTM:一种P2P系统中基于群组的信任模型
GBTM:A Group-Based Trust Model for P2P Systems
摘要
Abstract
Due to lack of effective mechanisms to improve the security performance of the system, there are a lot of malicious behaviors in P2P network. So,the trust model is an important research topic for the P2P application. It conducts the research on F2P network based on the trust model and divides different groups by the interest between peers. In this model,the global trust value can be computed by combining the trust value in direct peer,in interest group,between interest groups and multiple control factors. Through the simulation experiment, this model is verified to have high ratio of successful download,and the peer load can be controlled in a admissible range.关键词
