ABSTRACT:
A system and method for enabling encryption and/or authentication services on a telephony network. A portable information device, such as a personal digital assistant is used to exchange encryption and/or authentication data with a second portable information device. The portable information devices may be linked to the telephony network to enable encryption and/or authentication services using the encryption and/or authentication data exchanged by the portable information devices.
