Abstract: To estimate the trust value in P2P networks, an autonomous trust mode based on both direct experiences and recommendations is proposed, in which the recommendation synthetic coefficients are decided by the trustor’s trust on the recommendation subscribers. Both the direct trust and the recommendation trust are attenuated with time intervals. The corresponding data structure and an iterative computational method are given.

Key words: network security, distribute, trust, reputation, peer-to-peer network (P2P network)
