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.

"WebWhile anonymity and confidentiality appear to be orthogonal properties, making anonymous communication confidential is more involved than one might expect, since the ciphertext might reveal which public key has been used to encrypt. To address this problem, public-key cryptosystems with enhanced security properties have been proposed. " - Cryptography from anonymity
