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.

Identity-Based access control for ad hoc groups

TL;DR: An identity-based group admission control technique which avoids certain drawbacks of previous (certificate-based) approaches and also proposes a companion membership revocation mechanism which is robust, fully distributed, scalable and, at the same time, reasonably efficient.

Feasibility characterization of cryptographic primitives for constrained (wearable) IoT devices

TL;DR: The findings show that wearable devices of today have the needed potential to efficiently operate with cryptographic primitives in real time, and it is believed that the data provided during this research would shed light on what devices are more suitable for certain cryptographic operations.

Certificateless public key encryption with keyword search

TL;DR: Certifcateless Public Key Cryptography (CLPKC) is introduced into PEKS, and a general model of CertifCateless PEKS (CLPEKS) is formalized and a practical CLPEKS scheme is constructed with security and efficiency analyses.

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.
