Pairing-free Blind Signatures in the ROM

Abstract: Blind signatures are a cryptographic protocol that allows to issue digital signatures such that privacy of the signed message is preserved, with several applications in privacy-preserving technologies, such as anonymous credentials or electronic cash. In this talk, I will discuss how to construct blind signatures in prime-order groups in the random oracle model (ROM), with a focus on the recent techniques to avoid further idealizations (such as the GGM or AGM) under well-founded assumptions
