In this paper, a novel access control scheme based on Bayesian trust network is developed to address to the security services in P2P environments. The trust mechanism is constructed with Bayesian network model, which could describe precise trust degree of the P2P node responding to various operation or access. The model of access control is proposes with Bayesian trust network of P2P members, and...
Nowadays, most of access control models have been studied extensively in centralized and static environment, and they seldom meet the requirements of some dynamic collaborative environments, such as Grid, P2P and ad-hoc network. In this paper, the trust mechanism of the agents in collaborative environments is analyzed, a suitable method is introduced for calculating the agentpsilas trust in collaborative...
