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.

Invisibly Sanitizable Digital Signature Scheme

TL;DR: The proposed digitally signed document sanitizing scheme is based on the aggregate signature derived from bilinear maps and can sanitize a signed document invisibly, that is, no one can distinguish whether the signed document has been sanitized or not.

Efficient short signcryption scheme with public verifiability

TL;DR: This paper presented a short signcryption scheme to achieve both efficiency and security, and the security of the scheme is tightly related to q-Strong Diffie-Hellman problem in the random oracle model.

An Enhanced Secure Identity-Based Certificateless Public Key Authentication Scheme for Vehicular Sensor Networks

TL;DR: An improved authentication scheme using certificateless public key cryptography is proposed to address problems of vehicular sensor networks and can obtain better trade-offs between security and efficiency than the well-known available schemes.

Fair exchange protocol of signatures based on aggregate signatures

TL;DR: This paper enhances the fair exchange protocol of signatures against three types of inside attackers but also relax the need of the trust in the adjudicator so that it only needs to be trusted by the signer.

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.
