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.

Efficient Algorithms for Pairing-Based Cryptosystems.

TL;DR: In this paper, fast new algorithms for scalar multiplication in characteristic 3 and square root extraction over Fpm were proposed, with the latter technique being also useful in contexts other than pairing-based cryptography.

Resilient In-Network Aggregation for Vehicular Networks

TL;DR: A generic mechanism combination and adaptation framework is proposed, which uses each mechanism in the situations for which it is most suitable, avoiding drawbacks of individual mechanisms in other traffic situations.

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.
