A Method to Implement Direct Anonymous Attestation

چکیده

In this report we present an efficient anonymous authentication scheme that works in a manner similarly to the so-called Direct Anonymous Attestation in the setting of the Trusted Computing Platform. Our construction implements features such as total anonymity, variable anonymity, and rogue TPM tagging. The new scheme is significantly simpler, and more efficient than the current solution that has been adopted in the standard specification, which implies our scheme might be deployed in the similar settings. We have proved the new scheme is secure under the strong RSA assumption, and the decisional Diffie-Hellman assumption.

Formal Analysis of Anonymity in ECC-Based Direct Anonymous Attestation Schemes

A definition of user-controlled anonymity is introduced for Direct Anonymous Attestation schemes. The definition is expressed as an equivalence property suited to automated reasoning using ProVerif and the practicality of the definition is demonstrated by examining the ECC-based Direct Anonymous Attestation protocol by Brickell, Chen & Li. We show that this scheme is secure under the assumption...

Formal analysis of privacy in Direct Anonymous Attestation schemes

This article introduces a definition of privacy for Direct Anonymous Attestation schemes. The definition is expressed as an equivalence property which is suited to automated reasoning using Blanchet’s ProVerif. The practicality of the definition is demonstrated by analysing the RSA-based Direct Anonymous Attestation protocol by Brickell, Camenisch & Chen. The analysis discovers a vulnerability ...

Covert Identity Information in Direct Anonymous Attestation (DAA)

Direct anonymous attestation (DAA) is a practical and efficient protocol for authenticated attestation with satisfaction of strong privacy requirements. This recently developed protocol is already adopted by the Trusted Computing Group and included in the standardized trusted platform module TPM. This paper shows that the main privacy goal of DAA can be violated by the inclusion of covert ident...

Direct Anonymous Attestation: Enhancing Cloud Service User Privacy

We introduce a privacy enhancing cloud service architecture based on the Direct Anonymous Attestation (DAA) scheme. In order to protect user data, the architecture provides cloud users with the abilities of controlling the extent of data sharing among their service accounts. A user is then enabled to link Cloud Service applications in such a way, that his/her personal data are shared only among...

Direct Anonymous Attestation for Next Generation TPM

Trusted computing platforms have been proposed as a promising approach to enhance the security of general-purpose computing systems. Direct Anonymous Attestation(DAA) is a scheme that allows a Trusted Platform Module (TPM) which is the core component of the trusted computing platform to remotely convince a communication partner that it is indeed a Trusted Platform Module while preserving the us...
