Logcrypt: Forward Security and Public Verification for Secure Audit Logs

Jason E. Holt and Kent E. Seamons

Abstract: Logcrypt provides strong cryptographic assurances that data stored by a logging facility before a system compromise cannot be modified after the compromise without detection. We build on prior work by showing how log creation can be separated from log verification, and describing several additional performance and convenience features not previously considered.
