Abstract: A security enabler device has a key management module adapted to generate and store security keys and to destroy the generated keys if necessary to protect security. An encryption and authentication module is linked to the data storage module and is adapted to use the security keys to provide secure network communications for a terminal device connected to or incorporated in the security enabler device. The key management module operates in conjunction with an operating code module to prevent access to at least one of the security keys from outside the security enabler device.

Abstract: A modular communication server provides a single communication interface between a host and a number of communication devices. The modular communication server can be configured to support multiple communication devices using one or more communication protocols. The modular communication server includes a master communication controller that provides the interface between the network and devices using a first communication protocol. Slave communication controllers can be connected to a bus internal to the modular communication server. Each of the slave communication controllers can independently support devices using a communication protocol. The master communication controller controls the communication between the host and each slave communication controller.
