Cryptography from anonymity
WebIn this paper, we studythe possibility of using anonymous communication as a building block, and show that one can leverage on anonymity in a variety of cryptographic contexts. Our results go in two directions. ffl Feasibility. 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.
