This paper describes the direct anonymous attestation scheme (DAA). This scheme was adopted by the Trusted Computing Group (TCG) as the method for remote authentication of a hardware module, called Trusted Platform Module (TPM), while preserving the privacy of the user of the platform that contains the module. DAA can be seen as a group signature without(More)
Direct Anonymous Attestation (DAA) is a scheme that enables the remote authentication of a Trusted Platform Module (TPM) while preserving the user's privacy. A TPM can prove to a remote party that it is a valid TPM without revealing its identity and without linkability. In the DAA scheme, a TPM can be revoked only if the DAA private key in the hardware has(More)
Hardware side channel vulnerabilities have been studied for many years in embedded silicon-security arena including SmartCards, SetTop-boxes, etc. However, because various recent security activities have goals of improving the software isolation properties of PC platforms , software side channels have become a subject of interest.

Direct Anonymous Attestation (DAA) is a cryptographic mechanism that enables remote authentication of a user while preserving privacy under the user's control. The DAA scheme developed by Brickell, Camenisch, and Chen has been adopted by the Trust Computing Group (TCG) for remote anonymous attestation of Trusted Platform Module (TPM), a small hardware(More)
Enhanced Privacy ID (EPID) is a cryptographic scheme that enables the remote authenti-cation of a hardware device while preserving the privacy of the device. EPID can be seen as a direct anonymous attestation scheme with enhanced revocation capabilities. In EPID, a device can be revoked if the private key embedded in the hardware device has been extracted(More)
—Enhanced Privacy ID (EPID) is a cryptographic scheme that enables the remote authentication and attestation of a hardware device while preserving the privacy of the device. EPID can be seen as a direct anonymous attestation scheme with enhanced revocation capabilities. In EPID, a device can be revoked if the private key embedded in the hardware device has(More)
