Revocation of Direct Anonymous Attestation
2011Direct Anonymous Attestation (DAA) is a special type of anonymous digital signatures, used by the Trusted Computing Group (TCG) for the purpose of computer platform attestation whilst preserving platform anonymity. Like any other anonymous cryptographic primitives, how to efficiently revoke an existing member who is no longer legitimate, is an ...

Multi-domain Direct Anonymous Attestation Scheme from Pairings
, 2014 In trusted computing, a Trusted Platform Module(TPM) is used to enhance the security of the platform. When the TPM proofs his identity to a remote verifier, the Direct Anonymous Attestation (DAA) method is adopted by the Trusted Computing Group(TCG) to provide anonymous authentication.

Direct Anonymous Attestation (DAA) in More Depth
2014Direct Anonymous Attestation is TPM2’s method of providing mathematically-proven anonymity or pseudonymity for signing keys in trusted platforms. The simple explanation of how DAA works is that it has a single verification (public) key but a plethora of signing (private) keys. One cannot tell which of many platforms created the signature.

Improving the security of direct anonymous attestation under host corruptions
International Journal of Information Security, 2020Direct anonymous attestation (DAA) enables a platform including a trusted platform module (TPM) to produce a signature in order to remotely attest that it is in a certified state while preserving its anonymity. A main feature of DAA is that a TPM and a host together act as a signer, where the TPM is less powerful but trustworthy, whereas the host is ...

Direct Anonymous Attestation in practice: Implementation and efficient revocation
2014 Twelfth Annual International Conference on Privacy, Security and Trust, 2014 Direct Anonymous Attestation (DAA) is a signature scheme that provides a balance between user privacy and authentication in a reasonable way. The first RSA-based DAA is proposed in 2004, since then several ECC-based DAA schemes are proposed to achieve better performance. To analyze DAA schemes from a practical point of view, it is necessary to consider

Design and Analysis on Direct Anonymous Attestation for Security Chip
2011 2nd International Symposium on Intelligence Information Processing and Trusted Computing, 2011 Direct Anonymous Attestation (DAA) is an anonymous protocol designed for TPM/TCM or other embedding devices. Recently, DAA schemes based on the pairing continues to advance rapidly, but it has a certain problems to put the scheme into application. This paper focuses on the practicability and feasibility for the design of the pairing DAA protocol and ...

A Time-and-Times-Limited Strong Direct Anonymous Attestation Scheme
2009 International Conference on Business Intelligence and Financial Engineering, 2009Direct Anonymous Attestation (DAA) has been adopted in Trusted Platform Module v 1.2 (TPM v1.2) Specification, described by Trusted Computing Group (TCG). It intends to solve the trusted platform attestation and the platform privacy protection. In DAA, the certificate can be used repeatedly and this will provide the opportunities for rogue TPMs to ...

A delegation based cross trusted domain direct anonymous attestation scheme
Computer Networks, 2015Direct Anonymous Attestation (DAA) is a complex cryptographic protocol for remote attestation and provides both signer authentication and privacy. It was adopted by the Trusted Computing Group (TCG) as a technical standard. However, the DAA scheme in TCG specifications is designed for the single trusted domain attestation, and cannot be deployed in ...

A Direct Anonymous Attestation Protocol Based on Hierarchical Group Signature
2009 International Conference on Computational Science and Engineering, 2009Virtualization makes virtual machines with a wide range of security requirements run simultaneously on the same commodity hardware. Direct Anonymous Attestation (DAA) for virtual machine is a cryptographic mechanism that enables remote attestation of virtual machine instances ( VMIs ) while preserving privacy under the user’s control.
