Short Signatures from the Weil Pairing

TLDR
A short signature scheme based on the Computational Diffie-Hellman assumption on certain elliptic and hyperelliptic curves is introduced, designed for systems where signatures are typed in by a human or signatures are sent over a low-bandwidth channel.
Abstract
We introduce a short signature scheme based on the Computational Diffie-Hellman assumption on certain elliptic and hyperelliptic curves. The signature length is half the size of a DSA signature for a similar level of security. Our short signature scheme is designed for systems where signatures are typed in by a human or signatures are sent over a low-bandwidth channel.

A secure signature scheme from bilinear maps

TL;DR: In this article, the authors suggest that anonymity is the most relevant security property for undeniable and confirmer signatures and give a precise definition of anonymity for the multi-user setting and show that anonymity can be achieved even when the parties use completely different cryptographic primitives.

FPGA Implementations of Pairing using Residue Number System and Lazy Reduction

TL;DR: This paper presents two FPGA-based high speed pairing designs using the Residue Number System and lazy reduction, and shows that by combining RNS, which is naturally suitable for parallel architectures, and lazy Reduction, the speed of pairing computation in hardware can be largely increased.

Identity-based proxy signature from pairings

TL;DR: This paper redefines the security models of identity based proxy signature to capture the most stringent attacks against adaptively chosen message and chosen identity attacker and proposes a new provably secure identity basad proxy signature scheme whose security is based on the hardness of Computational Diffie-Hellman problem in the random oracle model.

Random oracles are practical: a paradigm for designing efficient protocols

TL;DR: It is argued that the random oracles model—where all parties have access to a public random oracle—provides a bridge between cryptographic theory and cryptographic practice, and yields protocols much more efficient than standard ones while retaining many of the advantages of provable security.

A digital signature scheme secure against adaptive chosen-message attacks

TL;DR: A digital signature scheme based on the computational difficulty of integer factorization possesses the novel property of being robust against an adaptive chosen-message attack: an adversary who receives signatures for messages of his choice cannot later forge the signature of even a single additional message.
