密钥托管密码体制不仅能保护用户的隐私权，同时允许法律授权下的监听．该文基于Ｒａｂｉｎ加密算法，提出了一种新的密钥托管方案．用户按Ｒａｂｉｎ加密算法加密自己的密钥，Ｒａｂｉｎ加密算法的秘密密钥由可信中心产生，并按中国剩余定理分配给两个委托人，当且仅当两个委托人联合起来，才能得到Ｒａｂｉｎ加密算法的秘密密钥，从而得到用户的密钥．
Key escrow password system can not only protect the privacy of users, while allowing the law under the supervision of. This paper proposes a new key escrow scheme based on Rabin encryption algorithm. The user encrypts his own key according to Rabin’s encryption algorithm. The secret key of Rabin’s encryption algorithm is generated by the trusted center and assigned to two principals according to China’s remainder theorem, and Rabin can be obtained only if the two principals join together Encrypt the algorithm’s secret key to get the user’s secret.
