Using Undeniable Signature on Elliptic Curves to Verify Servers in Outsourced Computations

Abstract

When carrying out outsourced cryptographic computations, it is possible not only to have errors in server computations but also to interact with a malicious computing server. In this paper, we propose an undeniable signature protocol adapted for a group of points of elliptic curve. We also present an outsourced algorithm for elliptic curve point multiplication.
