| Abstract: | We propose an efficient, scalable, certification-based key recovery system that is a hybrid of the key escrow and key encapsulation techniques. The proposed key recovery system is highly flexible and can be employed in a variety of policy environments. It possesses the properties required for commercial key recovery systems. We demonstrate the claims by comparing the computation and communication requirements for our proposal with a key recovery solution implemented by IBM.
