Abstract

Abstract: 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.

Key words: key management, hyper-elliptic curves, key protection, signature authentication and data recovery

摘要： 分析了现有密钥管理方案的安全漏洞，基于超椭圆曲线密码提出了一类密钥管理方案，并对方案的安全性与执行效率进行了深入分析;方案中协议与算法安全、简洁、高效，降低了软硬件实现的系统开销，可广泛应用于计算机与无线通信等网络环境。
