We construct two new multiparty digital signature schemes that allow multiple signers to sequentially produce a compact, fixed-length signature. First, we introduce a new primiti...

Motivated by the conflict between authenticity and privacy in the digital signature, the notion of limited verifier signature was introduced [1]. The signature can be verified by a...

We investigate the possibility to prove security of the well-known blind signature schemes by Chaum, and by Pointcheval and Stern in the standard model, i.e., without random oracle...

We give a short constant-size group signature scheme, which we prove fully secure under reasonable assumptions in bilinear groups, in the standard model. We achieve this result by ...
