Abstract

Proxy multi-signature system is based on digital signature scheme for a class of special signature scheme, which requires the signer to own certain powers were delegated to each proxy signer to make these proxy signer to use these powers on behalf of himself. In this paper, a class before the enhanced proxy multi-signature scheme carry out the attack and improvement, three forgery attacks has been implemented,one for the any original signer,one for the any proxy signer,and one for the proxy signer modify the proxy deadline. While the original proposals put forward an improved model, to prevent a proxy signer rights transfer, the ability to prevent abuse of the signature to ensure that the proxy signature security.
