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.

On the Application of Identity-Based Cryptography in Grid Security

Hoon Wei Lim
TL;DR: This thesis discusses how this TLS-like identitybased secret public key protocol can be applied to securing interactions between users and credential storage systems, such as MyProxy, within grid environments and introduces new password-based protocols using identity- based secret public keys.

Aggregating CL-Signatures Revisited: Extended Functionality and Better Efficiency

TL;DR: In this article, the authors proposed two aggregate signature schemes based on the Camenisch-Lysyanskaya (CL) signature scheme whose security is reduced to that of CL signature (i.e., secure under the LRSW assumption).

Use of isogenies for design of cryptosystems

TL;DR: In this paper, isogenies of Abelian varieties (e.g., elliptic curves in one-dimensional cases) are utilized to provide public-key encryption systems, and solutions are disclosed for generating the Isogenies.

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.
