A SIGNATURE SCHEME FOR DIRECT ANONYMOUS ATTESTATION
R. Anitha, Swarun Kumar · 2013
Direct anonymous attestation (DAA) is a scheme developed for remote authentication of a hardware module and trusted platform module (TPM), while preserving the privacy of the user of the platform that contains the module. In Previous technique, a TPM can be revoked only if the DAA private key in the hardware has been extracted so that if the TPM is found to be compromised after the DAA issuing has occurred. The proposed present a EPID Scheme (Enhanced Privacy ID) builds on top of the DAA scheme and applies Camenisch-Lysyanskaya (CL) signature scheme. EPID is efficient and provably secure in the random oracle model to provide high security scheme a concept of DRAFT has to check the integrity status of the intermediate node to gain the attestation.
