Abstract

In 1998, A. Young and M. Yung introduced the concept of ARC that conjugates functionalities of a typical PKI with the ability to escrow private keys of the system users. And in 1999, P. Paillier and M. Yung proposed a new notion - called SE-PKI - which presents other additional advantages beyond ARC. Also in 2000, Hi-Jong, Yu et al proposed the key recovery system with multiple escrow agents which has shared secret theory. In this paper, we propose the key recovery system that can recover the secret key of users on on-line communication. Only a user can recovery private key at the system. In case of changing frequently user's secret key, it is easy to manage the secret key in order to decrypt ciphertexts in the key recovery system.
