Title: Method of recovering ciphered session key and device therefor
Inventor: YAAYA WAI ARU SARUKUAN
IPC: H04L9/08
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To enable a session key to be recoverable for a ciphered message even if an addressee forgets or loses his own private key. SOLUTION: A session key is ciphered by using a public key of an authentication organization other than an addressee intended by a message, and sent to an authentication organization knowing personal information on the addressee. If inputted personal information agrees or approximately agrees with retrieved information, the authentication organization is able to decipher the session key by using its own key. And then, the addressee can decipher the message by using the session key without telling his private key to others, and also without notifying the authentication organization of his public key. A law executing organization cuts off the message with a public key of the authentication organization; supplies an order from a court; retrieves the session key; and can decipher the message without letting the addressee know it.
