摘要
Abstract
For the problem of some trust mechanisms in P2P network don’t take fuzziness and randomness into consideration comprehensively,this paper proposed the cloud model into trust mechanism.It predicted the behavior of nodes according to the gray system theory,and determined whether the node was trustworthy from the characteristic parameters of cloud model,inclu-ding the value of the average level of trust and discrete level.The simulation results show that the mechanism can effectively identify malicious nodes which behavior are unstable and reduce their chances of participating in the network by cutting the its trust value,reaching the goal of improving the trading success rate of the system,and ensuring the security of the network.关键词
