WebAlthough achieving anonymity can be an important design criterion in cryptographic systems, it comes at a cost. If the systems are not carefully designed, the overall security of the system could be compromised. Our goal is to develop mathematical techniques that enable anonymity in cryptographic systems without compromising the security. WebDirect Anonymous Attestation (DAA) is a cryptographic primitive which enables remote authentication of a trusted computer whilst preserving privacy of the platform's user. The protocol has been adopted by the Trusted Computing Group (TCG) in the latest version of its Trusted Platform Module (TPM) specification to address privacy concerns (see also Loss … signs a person has had a stroke

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. signs a person had a stroke

Webcryptography itself appears to be sound and to deliver the promised anonymity. These schemes are far less satisfactory, however, from a law enforcement point of view. In particular, the dangers of money laundering and counterfeiting are potentially far more serious than with paper cash. These problems exist 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 ...

WebJan 19, 2024 · Ring signatures show more solid user anonymity than group signatures. The strong user anonymity of ring signatures supports ring signatures for whistleblowing, e-voting, e-cash, e-bidding, and e-lottery. Recently, ring signatures became a prominent candidate for cryptocurrency uses.
