ePrint Report: Blind signatures from Zero knowledge in the Kummer variety

Paulo L. Barreto, Devin D. Reich, Marcos A. Simplicio Jr., Gustavo H. M. Zanon

We show how to apply the BZ methodology (Blind signatures from Zero knowledge) to obtain blind signatures in the Kummer varieties defined by Montgomery curves. We also describe specially-tailored arithmetic algorithms to facilitate their efficient implementation. The result can be proved secure under appropriate assumptions, appears to resist even the ROS attack (to which most …
