A Provably Secure Proxy Signature Scheme in Certificateless Cryptography
A proxy signature scheme enables an original signer to delegate its signing capability to a proxy signer and then the proxy signer can sign a message on behalf of the original sign...

A Group Signature Scheme from Lattice Assumptions
Group signature schemes allow users to sign messages on behalf of a group while (1) maintaining anonymity (within that group) with respect to an observer, yet (2) ensuring traceab...

A Lattice-Based Threshold Ring Signature Scheme
In this article, we propose a new lattice-based threshold ring signature scheme, modifying Aguilar’s code-based solution to use the short integer solution (SIS) problem as securi...

A Study of the Security of Unbalanced Oil and Vinegar Signature Schemes
The Unbalanced Oil and Vinegar scheme (UOV) is a signature scheme based on multivariate quadratic equations. It uses m equations and n variables. A total of v of these are called ...

Design Validations for Discrete Logarithm Based Signature Schemes
A number of signature schemes and standards have been recently designed, based on the Discrete Logarithm problem. In this paper we conduct design validation of such schemes while t...
