A Practical Multivariate Blind Signature Scheme
Albrecht Petzoldt, Alan Szepieniec, and Mohamed Saied Emam Mohamed
Abstract
Multivariate Cryptography is one of the main candidates for creating post-quantum cryptosystems. Especially in the area of digital signatures, there exist many practical and secure multivariate schemes. However, there is a lack of multivariate signature schemes with special properties such as blind, ring and group signatures. In this paper, we propose a generic technique to transform multivariate signature schemes into blind signature schemes and show the practicality of the construction on the example of Rainbow. The resulting scheme satisfies the usual blindness criterion and a one-more-unforgeability criterion adapted to MQ signatures, produces short blind signatures and is very efficient.
