Abstract :
By the analysis of a proxy multi-signature scheme based on elliptic curve discrete logarithm problem proposed by Cao, this paper points out that it still has drawbacks, such as the absence of distinguishablility and undeniability properties, presence of proxy misuse. A new proxy multi-signature scheme with proxy revocation is proposed, which can resolve the proxy revocation and prevent proxy misuse by adding a signature center.
