Hash-based Direct Anonymous Attestation [PDF]
, 2023 Direct Anonymous Attestation (DAA) was designed for the Trusted Platform Module (TPM) and versions using RSA and elliptic curve cryptography have been included in the TPM specifications and in ISO/IEC standards. These standardised DAA schemes have their security based on the factoring or discrete logarithm problems and are therefore insecure against ...

Covert Identity Information in Direct Anonymous Attestation (DAA) [PDF]
, 2007 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.
