Subversion-Resilient Signatures: Definitions, Constructions and Applications
Eprint
https://eprint.iacr.org/2015/517
Giuseppe Ateniese Bernardo Magri Daniele Venturi
We provide a formal treatment of security of digital signatures against subversion attacks (SAs). Our model of subversion generalizes previous work in several directions, and is inspired by the proliferation of software...

Quasi-Efficient Revocation of Group Signatures
Eprint
https://eprint.iacr.org/2001/101
Giuseppe Ateniese Dawn Song Gene Tsudik
A group signature scheme allows any group member to sign on behalf of the group in an anonymous and unlinkable fashion. In the event of a dispute, a designated trusted entity can reveal the identity of the signer. Group...

A Provably Secure Nyberg-Rueppel Signature Variant with Applications
Eprint
https://eprint.iacr.org/2004/093
Giuseppe Ateniese Breno de Medeiros
This paper analyzes the modified Nyberg-Rueppel signature scheme (mNR), proving it secure in the Generic Group Model (GM). We also show that the security of the mNR signature is equivalent (in the standard model) to that of a...

Giuseppe Ateniese Jan Camenisch Marc Joye Gene Tsudik
In \cite{Cao}, a putative framing ``attack'' against the ACJT group signature scheme \cite{ACJT00} is presented. This note shows that the attack framework considered in \cite{Cao} is \emph{invalid}. As we clearly illustrate,...

Antonio Faonio
In a recent paper Faonio, Nielsen and Venturi (ICALP 2015) gave new constructions of leakage-resilient signature schemes. The signature schemes proposed remain unforgeable against an adversary leaking arbitrary information on...
