WebWe investigate constructions as well as limitations for preserving receiver anonymity when using public-key encryption (PKE). We use the constructive cryptography approach by Maurer and Renner and interpret cryptographic schemes as constructions of a certain ideal resource (e.g. a confidential anonymous channel) from given real resources (e.g ... 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.
