Logs are important sources of the security audit systems, this paper analyzes the defects of traditional security audit systems, and proposes the forward-secure digital signature scheme as the tamper resistance protection of the server logs. Even if the signer´s private key is divulged, the attacker can still not recover the plain message of the signcryption of this and past time, so he can not tamper the logs which are encrypted before key exposed. In this paper, we describes the scheme´s theory and implementation. And we make simulation test and security analysis in detail. Finally, We come to the conclusion, the scheme can effectively resist any illegal tamper on historical logs.
