摘要

In this paper we introduce our variant of the digital signature HAWK, which is in the ongoing round 2 of NIST call for additional quantum-safe digital signature schemes. This work aims to reduce the stored bytes of the secret/signing key, and retrieve them from the public/verification key. We provide a demonstrative implementation and leave a proper C implementation as a future work.
