P2P环境中基于信誉与云理论的信任模型
Trust Model Based on Reputation and Cloud Theory in P2P Environment
摘要
Abstract
In P2P environment, most of the existing trust models can not reflect the subjectivity, fuzziness and uncertainty of trust. This paper presents a new trust model for P2P environment-CloudBT. In the calculation of the node global trust value, it introduces time weight function, and combines with cloud model to get the node trust value which integrates cloud model with reputation-based model to describe the measure and uncertainty of trust, and considers both the trust value of nodes and behavior of the fluctuations when making trust decisions. Simulation results show that the CloudBT model has the high success rate of trade and strong ability against the attack in P2P e-commerce environment.关键词
