Foundations of fully dynamic group signatures (2016)
Presentation / Conference Contribution

Group signatures are a central cryptographic primitive that has received a considerable amount of attention from the cryptographic community. They allow members of a group to anonymously sign on behalf of the group. Membership is overseen by a design... Read More about Foundations of fully dynamic group signatures.

Short accountable ring signatures based on DDH (2016)
Presentation / Conference Contribution

Ring signatures and group signatures are prominent cryptographic primitives offering a combination of privacy and authentication. They enable individual users to anonymously sign messages on behalf of a group of users. In ring signatures, the group,... Read More about Short accountable ring signatures based on DDH.

Short structure-preserving signatures (2016)
Presentation / Conference Contribution

© Springer International Publishing Switzerland 2016. We construct a new structure-preserving signature scheme in the efficient Type-III asymmetric bilinear group setting with signatures shorter than all existing schemes. Our signatures consist of 3...
