Building a trust and reputation mechanism in P2P system is very important. This paper gives an improved global trust value computing method of choosing trusted source peers in P2P system. First, we give a basic description of our trust mechanism; then we bring out the global trust value computing method; third, we define trust computing operator; fourth, we introduce other related trust mechanisms; and finally we do some simulations to compare the performance of our method with other trust mechanism.
