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

A Direct Anonymous Attestation Scheme Based on Mimic Defense Mechanism
2020 International Conference on Internet of Things and Intelligent Applications (ITIA), 2020Machine-to-Machine (M2M) communication is a essential subset of the Internet of Things (IoT). Secure access to communication network systems by M2M devices requires the support of a secure and efficient anonymous authentication protocol.

Direct Anonymous Attestation (DAA) in More Depth [PDF]
, 2014 Direct 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.

Universally Composable Direct Anonymous Attestation
International Conference on Theory and Practice of Public Key Cryptography, 2016Direct Anonymous Attestation DAA is one of the most complex cryptographic algorithms that has been deployed in practice. In spite of this and the long body of work on the subject, there is still no fully satisfactory security definition for DAA. This was already acknowledged by Bernard et al.

DAA-A: Direct Anonymous Attestation with Attributes
Trust and Trustworthy Computing, 2015The TPM 2.0 specification has been designed to support a new family of Elliptic Curve (EC) based Direct Anonymous Attestation (DAA) protocols. DAA protocols are limited to anonymous or pseudonymous attestations. But often a more flexible attestation would be needed.

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 ...
