Dear all,

Last week we presented a preview of our planned submission LEAST at NIST Workshop on Multi-Party Threshold Schemes 2026. LEAST is a suite composed of a Digital Signature with Threshold Signing and a Distributed Key Generation mechanism based on Cryptographic Group Actions instantiated from the Linear Code Equivalence Problem.

The Preview Writeup is available at https://csrc.nist.gov/csrc/media/Projects/threshold-cryptography/documents/TCall-1/LEAST-PW01.pdf We look forward to a constructive and enriching discussion.

We also want to take this opportunity to advertise the workshop MaGIC https://magic-workshop.github.io/. Co-organized by the LEAST and PQarrots teams, adjacent to Eurocrypt in time (May 5-8) and space (in the heart of Marche, a 2:30 train ride from Rome), MaGIC will explore all theoretical and practical aspects of Group Actions in Cryptography. Registration will open soon!
