According to the system of the present invention, a dedicated decryption server that has a secret key is employed in addition to a transmitter used by a sender and a receiver used by a recipient. While the presence of nonencrypted messages in the server is precluded, the server can decrypt an encrypted message and send the decrypted message to an authorized receiver.Other References
