Abstract:

Trustworthiness of the reputation information is the basis of the reputation systems under the P2P environ- ment. We propose a distributed reputation  information management system named RepMan, which provides the assurance for the security, reliability, accountability and efficiency on the trustworthi ness of the reputation information. RepMan can effectivdy diminish the influence of many kinds of malicious attacks against reputation systems, and it w ill work as a com- mon secure deployment mechanism for the distributed reputation system.

Key words: P2P ;distributed, reputation
