—In [1, 2, 3], we have introduced a robust and secure digital signature solution for multimedia content authentication, by integrating content feature extraction, error correctio...
Constructing practical and provably secure group signature schemes has been a very active research topic in recent years. A group signature can be viewed as a digital signature wit...
Abstract. We propose a variant of the “bonsai tree” signature scheme, a latticebased existentially unforgeable signature scheme in the standard model. Our construction offers ...
We initiate the study of unique group signature such that signatures of the same message by the same user will always have a large common component (i.e., unique identifier). It ...
We answer the open question of the possibility of building a digital signature scheme with proven security based on the one-wayness of a trapdoor permutation and with signatures as...
