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.read more

Improved proxy re-encryption schemes with applications to secure distributed storage
TL;DR: Performance measurements of the experimental file system demonstrate the usefulness of proxy re-encryption as a method of adding access control to a secure file system and present new re-Encryption schemes that realize a stronger notion of security.

Certificateless public key cryptography
TL;DR: In this article, the concept of certificateless public key cryptography (CL-PKC) was introduced and made concrete, which does not require certificates to guarantee the authenticity of public keys.

Short group signatures
TL;DR: In this paper, the authors proposed a group signature scheme based on the Strong Diffie-Hellman assumption and a new assumption in bilinear groups called the Decision Linear assumption.

Enabling Public Auditability and Data Dynamics for Storage Security in Cloud Computing
TL;DR: To achieve efficient data dynamics, the existing proof of storage models are improved by manipulating the classic Merkle Hash Tree construction for block tag authentication, and an elegant verification scheme is constructed for the seamless integration of these two salient features in the protocol design.

Random oracles are practical: a paradigm for designing efficient protocols
Mihir Bellare,Phillip Rogaway +1 more
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.
