Direct Anonymous Attestation (DAA) is a scheme that enables the remote authentication of a Trusted Platform Module (TPM) while preserving its privacy. To address the problem of the membership revocation of DAA, based on the dynamic accumulator, the authors propose Forward Secure Dynamic DAA scheme (FSDDAA), their scheme achieved efficient revocation on DAA scheme, i.e., the expense of revoke DAA member is independent on the number of current or total deleted members. Moreover, the utility of forward security mitigate the damage caused by key compromised, and ensure the signature signed by valid member is provided with backward unlinkability.
