The Fiat-Shamir Transform for Group and Ring Signature Schemes
The Fiat-Shamir (FS) transform is a popular tool to produce particularly efficient digital signature schemes out of identification protocols. It is known that the resulting signat...

Adaptive Security in the Threshold Setting: From Cryptosystems to Signature Schemes
Threshold cryptosystems and signature schemes give ways to distribute trust throughout a group and increase the availability of cryptographic systems. A standard approach in design...

A Generic Scheme Based on Trapdoor One-Way Permutations with Signatures as Short as Possible
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...

The Security of the FDH Variant of Chaum's Undeniable Signature Scheme
In this paper, we first introduce a new kind of adversarial goal called forge-and-impersonate in undeniable signature schemes. Note that forgeability does not necessarily imply im...

A Signcryption Scheme with Signature Directly Verifiable by Public Key
Signcryption, first proposed by Zheng [4,5], is a cryptographic primitive which combines both the functions of digital signature and public key encryption in a logical single step,...
