基于(r,n)门限的密钥恢复方案

Key Recovering Based on (r,n) Threshold Scheme

随着计算机技术的普及发展,信息安全越来越受到重视,许多系统借助加密技术来保证信息在存储传输过程中的安全性,而密码系统中所使用的密钥或口令的安全性则成为系统的薄弱环节,密钥的丢失会给用户造成不必要的损失。文中介绍了一种应用(r,n)门限进行密钥恢复的新方案,该方案综合应用门限技术和因特网中广泛使用的回答问题认证模式来恢复丢失的密钥或口令。与传统密钥的恢复方案相比,具有较好的易用性和安全性。

With the development of computer technology, information security is becoming more important than ever before. Lots of system deploys cryptogmphic technologies to insure the information＇s security during its storing and transmitting processes. One of the most eommon problems with cryptography system is that users sometimes forget their passwords or even lose their private keys. So proposes a new approach to recover the lost keys or passwords based on （ r, n ） threshold scheme. Compared with the traditional key recovery scheme, it is more available and feasible.
