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.

An Efficient CDH-based Signature Scheme With a Tight Security Reduction.

TL;DR: This paper proposes a new signature scheme that also has a tight security reduction to CDH but whose resulting signatures are smaller than EDL signatures, and which represents to date the most efficient scheme of any signature scheme with a tightSecurity reduction in the discrete-log setting.

Cryptographic Accumulators: Definitions, Constructions and Applications

TL;DR: The goal of this paper is to present a complete picture of the topic, starting from the issue of defining an adequate formalization for cryptographic accumulators, and then moving on to a description of known constructions.

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.
