摘要
介绍了密钥隔离公钥加密体制的基本思想,提出一种基于离散对数问题的密钥隔离数字签名体制,利用 Z 次多项式,将密钥分为用户密钥和系统密钥,签名时由用户密钥完成,密钥更新时由用户密钥和系统密钥合作完成。
Introduce the concept of Key-Insulated security. Construct a new Key-Insulated digital signature based on the discrete log problem. With the polynomial of degree Z, the key involve the user key and the master key, signing by the user key, key-updating by the user key and the master key.
