Improved key management scheme based on hyper-elliptic curves cryptosystem

After analyzing the shortcomings and security threats of the present key management schemes,we present a key management scheme for network environment based on hyper-elliptic curves cryptosystem that can gain a wide application in computer and wireless communication network.In the communication protocols,the processes of signature,authentication,encryption and decryption have been simultaneously completed in a single protocol process and the conventional crypto graphical protocols in data transferring have been greatly simplified without influencing the system's security.Further detailed analyses have also justified the scheme's brevity,security,high efficiency,and thus considerable improvement on system overheads regarding software and hardware application.
