Abstract

A computer data security system, useful in protecting audit logs, includes symmetric key based techniques, requires only a small-constant number of cryptographic hash operations at the signer side sending a prospective audit log or other computer record data to a primary repository to achieve forward-secure and append-only authentication. The verification is performed by independent parties sharing parts of the symmetric key, wherein the presence of single honest party among all verifier parties ensures a conditional non-repudiation. It also ensures that an active adversary cannot generate authentication tags on behalf of the signer, unless it compromises all verification parties.
