A Provably Secure Proxy Signature Scheme with Multiple Threshold Values Based on Elliptic Curve

摘要：

In this paper, we propose a threshold proxy signature scheme with multiple threshold values based on elliptic curve. The new scheme is simple, flexible and efficient since both the size of signature and verification computation do not depend on the number of actual proxy signers. Moreover, we show that the scheme is strongly unforgeable under the discrete logarithm assumption in the random oracle model.
