WebThis paper obtains the scheme with the most efficient Revocation Check among VLR schemes enabling Backward Unlinkability, and proposes a correction of their scheme to enable a full proof of the traceability property and an extension to ensure Backward unlinkability. Verifier-Local Revocation (VLR) group signatures, introduced by Boneh … WebA Group signature scheme is a method for allowing a member of a group to anonymously sign a message on behalf of the group. The concept was first introduced by David Chaum and Eugene van Heyst in 1991. For example, a group signature scheme could be used by an employee of a large company where it is sufficient for a verifier to know a message ...
WebThe size of the group signature and the verification time of the group signature are equivalent to that of an individual digital signature. In other words, the (t, n) threshold signature scheme has the following five properties: (i) any group signature is mutually generated by at least t group members; (ii) the size of the group signature is ...

In this work, we propose a new group signature scheme avoiding the ROM that halves the size and the computational complexity compared to the state-of-the-art [3]. More speci cally, our group signature only consists of 2304 bits which makes it very competitive, even against constructions in the ROM (seesection 6for more details). logistics operative interview questionsWebgroup signature scheme using these protocols as building blocks.
