Y. Lee & C. Laih

In this paper, we propose a new key escrow system which will meet the requirements of the key escrow and the key recovery systems. In this system, a true LEAF should be sent out. Hence the squeezing attack can be avoided and the law authorized investigation can be performed successfully. The system is secure and easy to be implemented in both hardware or software along with any well-known cryptosystem. The scheme provides privacy communications for users and protects social security for the government simultaneously. Moreover, the system can recover the lost keys for users, which make the system is beneficial to all users.
