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.

Practical Fully Secure Unrestricted Inner Product Functional Encryption Modulo p

TL;DR: Abdalla, Bourse, De Caro, and Pointcheval as discussed by the authors proposed adaptive functional encryption (FE) based on Decision Diffie-Hellman (DDH), Learning-with-Errors (LWE), and Paillier's Decision Composite Residuosity (DCR).

Verifiable Timed Signatures Made Practical

TL;DR: This work formalizes VTS, presents efficient constructions compatible with BLS, Schnorr, and ECDSA signatures, and experimentally demonstrates that these constructions can be employed in practice, and designs an efficient cut-and-choose protocol based on the homomorphic time-lock puzzles to prove the validity of a signature encapsulated in a time-locks.

History-Free sequential aggregate signatures

TL;DR: A construction based on the BLS signature scheme which satisfies the notion of history-free sequential aggregation for signatures where the new aggregate does not rely on the previous messages and public keys either, thus inhibiting the costly verifications in each aggregation step.

PSRide: Privacy-Preserving Shared Ride Matching for Online Ride Hailing Systems

TL;DR: The privacy leakage of online ridesharing matching is studied, a more complex and economy ORH service that allows riders to share rides with others, and a privacy-preserving shared ride matching scheme, called PSRide, which is implemented and analyzed thoroughly.

Designated-Verifier Provable Data Possession in Public Cloud Storage

TL;DR: This paper proposes designated verifier provable data possession (DV-PDP), a scheme that removed expensive bilinear computing from public clouds and is provable secure and high efficiency.

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.

Identity-Based Encryption from the Weil Pairing

TL;DR: This work proposes a fully functional identity-based encryption (IBE) scheme based on bilinear maps between groups and gives precise definitions for secure IBE schemes and gives several applications for such systems.

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.
