摘要
本文实现了基于椭圆曲线的密钥托管方案,简化了托管子密钥的传递,同时有效解决了托管子密钥的动态更新、动态分配问题,并且效率更高。方案的安全性是基于求解有限域上椭圆曲线离散对数的困难性。
In this paper,we propose a dynamic key escrow scheme based on elliptic curve cryptosystem.In the scheme,we simplify the transmission of escrowed key,also solve the problems of dynamic update and dynamic allocation of the escrowed key,besides,the scheme is more high efficiency.Security of this scheme is based on difficulty of solving discrete logarithm in finite filed.
