Japanese Patent JP3315126

B2

A method for enabling secure communications among processing devices first establishes a first cryptographically secure session between a first processing device and a second processing device. The first processing device is remotely located from the second processing device. A second cryptographically secure session is established between a third processing device and a fourth processing device which are also remotely located for each other. The first processing device communicates with the third processing device over a first communications link and the second processing device communicates with the fourth processing device over a second communications link. A session key is generated and stored in the first processing device. Session key information is also stored in the second processing device and is sent therefrom to the third processing device. The session key information is then generated in the third processing device at least in part from the received session key information and is then stored in the third processing device. A third cryptographically secure session is established between the first processing device and the third device using the session key.
