| Research Abstract |
A peer-peer (P2P) system is composed of peer processes, which is in nature fully distributed. Here, it is critical to discuss if each peer can trust an acquaintance. Since there is no centralized coordinator on member peers in the networks, each peer has to decide on the trustworthiness of each acquaintance by communicating with the acquaintances. In the traditional reputation concept, every trustworthiness opinion on the target peer is collected. Here, some malicious, obsolete opinions might be included. In this research, we discussed a novel way where each peer only takes a subjective trustworthiness on a target peer from acquaintances which the peer can trust. Through the simulation, we showed the objective trustworthiness obtained by the algorithm we discussed is more accurate than the flooding ones. In addition, a peer might obtain the subjective trustworthiness on a target peer different from the objective one.
