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 and Privacy-Preserving Online Medical Prediagnosis Framework Using Nonlinear SVM

TL;DR: It is shown that eDiag can ensure that users’ health information and healthcare provider's prediction model are kept confidential, and has significantly less computation and communication overhead than existing schemes.

Dynamic k -times anonymous authentication

TL;DR: In this paper, a dynamic k-times anonymous authentication (k-TAA) scheme is proposed, in which application providers can independently grant or revoke users from their own groups and so have the required control on their clients.

CloudSeal: End-to-End Content Protection in Cloud-Based Storage and Delivery Services

TL;DR: This work proposes CloudSeal, a scheme for securely sharing and distributing data via cloud-based data storage and content delivery services, which ensures the confidentiality of content stored in public cloud storage services, by encrypting it before sharing at the cloud.

A Scalable Scheme for Privacy-Preserving Aggregation of Time-Series Data

Marc Joye, +1 more
TL;DR: This paper presents a practical scheme which, advantageously, can accommodate large plaintext spaces, is efficient for both encryption and decryption/aggregation and can operate in an off-line/on-line mode.

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.
