-signHD: A New Structure for the SQIsign Family with Flexible Applicability
Abstract
Digital signature is a fundamental cryptographic primitive and is widely used in the real world. Unfortunately, the current digital signature standards like EC-DSA and RSA are not quantum-resistant. Among post-quantum cryptography (PQC), isogeny-based signatures preserve some advantages of elliptic curve cryptosystems, particularly offering small signature sizes. Currently, SQIsign and its variants are the most promising isogeny-based digital signature schemes.
In this paper, we propose a new structure for the SQIsign family: Pentagon Isogeny-based Signature in High Dimension (referred to as
