Multi-party Authorization Signature Scheme Based on Hyper-elliptic Curves Cryptosystem

This paper analyzes multi-party authorization scheme in electronic business,as well as multi-signature scheme in network communication.Based on hyper-elliptic curves cryptosystem,it presents a hybrid multi-signature scheme that can gain a wide application in computer and wireless communication network.Avoiding security breach,such as information leak and signature forgery scheme,and disadvantage,such as complexity of protocol process,computation expenses for signature certification,it proposes a hybrid multi-signature,and analyzes security and execution efficiency of the scheme.The protocol and algorithm are brief,secure,highly-efficient,which can reduce the system overhead for implementation of software and hardware,so it can be applied to the environment of computer and wireless communication network.
