Key escrow cryptography has been becoming popular recently. A key escrow system bridges the gap between users' privacy and social need for protection against criminal behavior. However, there are some disadvantages and controversies regarding the system. In this paper we review and analyze the weaknesses of several recent protocols. The protocols are examined with respect to their claimed issues.
