Abstract
The LESS signature scheme, introduced in 2020, represented a fresh start for code-based signatures. In this paper we explore advanced functionalities for signature schemes, stemming from the work of LESS. First, we adapt a recent protocol of Beullens et al. to obtain a construction for (linkable) ring signatures. Then, we realize an identity-based signature scheme following the traditional approach by Joye and Neven. Our performance numbers confirm that signature schemes based on the code equivalence problem have considerable potential for practical applications.File in questo prodotto:
