Abstract :
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 dynamically manages the access permission according to the Bayesian trust network of subject and object.
