摘要：For the large scale of the network and unreliable nature of peers in most P2P (Peer-to-Peer) systems, it is a challenging task to implement an efficient and robust P2P reputation system. Self-storage P2P reputation systems provide an efficient way to retrieve rating values. Since each peer locally stores its own rating values given by all other peers, it takes only one query message to collect all the rating values of a peer. However, it also gives the owner control over its rating values. One of the challenges of this type of system is to protect the rating values from being maliciously modified by their owners. In existing self-storage P2P reputation systems, other participants are involved in order to ensure the integrity and reliability of the rating values. However, because at least one participant must be contacted during the rating and rating values retrieval processes, they create a high message overhead when deployed in unstructured P2P systems.
