Research an Evaluation of Transaction Trust Model for P2P Network
With an intention of protecting P2P network from threats of frand by means of trust accumulation, a transaction evaluation-based trust model is proposed. Transaction history and evaluation information of nodes are used to assess their trusting level. Satisfaction degree and transaction size are employed to make the prestige value of nodes to rise slowly but drop down sharply. Malicious attacks are detected and a punishment function is defined to guard against such attacks. Besides, An additional prestige and contribution value, which is computed from online time, upload contents and so on, is combined to strengthen anti-attack performance and stability of P2P ndes. Experimentation simulation verified the protection performance of proposed model.
