Pairing-Free Blind Signatures from Standard Assumptions in the ROM

ePrint Report: Pairing-Free Blind Signatures from Standard Assumptions in the ROM

Julia Kastner, Ky Nguyen, Michael Reichle

Blind Signatures are a useful primitive for privacy preserving applications such as electronic payments, e-voting, anonymous credentials, and more. However, existing practical blind signature schemes based on standard assumptions require either pairings or lattices. We present the first construction of a round-optimal blind signature in the random oracle model based on standard assumptions without resorting to pairings or lattices. In particular, our construction …
