Title: Key escrow system
Inventor: INOUE TORU
IPC: H04L9/08
Filed: 2001-02-26
Abstract: PROBLEM TO BE SOLVED: To enhance security of a key escrow system, and also surely deposit a shared key for use in encryption communication. SOLUTION: Each user finds a point on an elliptic curve, and defines the point as public information. A user A finds a public key from own public information and secret information shared between users. When the user A wants to perform encryption communication with a user B, the public key of the user A and the public information of the user B are sent to an escrow agency EA. The escrow agency EA generates a shared key from the public key and the public information, by using paring technique of the point of the elliptic curve, and delivers them to the users A, B. When an investigation agency intercepts the encryption communication under the law, the investigation agency asks the escrow agency EA for delivery of the shared key. Since the shared key is deposited and the secret key is not distributed, the security of the communication is enhanced.
