Abstract: Detailed analysis are made on the proxy digital signature in network comunication and a proxy digital signature scheme for network environment based on elliptic curves cryptosystem that can gain a wide application in computer and wireless communication network is presented. Further detailed analysis justify its breviy, security, high efficiency, and thus considerable improvement on system overheads regarding software and hardware application.
