WebJun 16, 2024 · We call the resulting notion anonymity “in the traceable case” which implies the branch-hiding property of BiAS. We augment this anonymity notion with the anonymity “in the non-traceable case” where all the signatures are generated from a predicate value equals to 1, i.e., from the branch leading to unconditional anonymity. WebDirect Anonymous Attestation (DAA) is a cryptographic primitive which enables remote authentication of a trusted computer whilst preserving privacy of the platform's user.
