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...

Improving the Exact Security of Digital Signature Schemes
We put forward a new method of constructing Fiat-Shamir-like signature schemes that yields better "exact security" than the original Fiat-Shamir method. (We also point o...

How to Strengthen Any Weakly Unforgeable Signature into a Strongly Unforgeable Signature
Standard signature schemes are usually designed only to achieve weak unforgeability – i.e. preventing forgery of signatures on new messages not previously signed. However, most s...
