A storage scheme of reputation based on RSA threshold secret sharing and one-way function is proposed in Peer-to-Peer networks. In this scheme, reputation information is divided into n shares and distributed to n participants. Any t or more than t participants can reconstruct reputation information base on RSA threshold secret sharing. The validation share corresponding to the secret share is also distributed to every participant for verifying the integrity of secret share and any cheat behavior will be detected no matter who is from rightful participant or unlawful participant. The scheme is secure unless RSA cryptography and one-way function can be break through. This scheme can also defend collusion and man-in-the-middle attack.
