Reconfiguration security for hardware agents in testing

This paper presents a new method for assuring security in a distributed system using agents and reconfigurable circuits. The agents are used to implement an extension of the El Gamal encryption algorithm, used for conferring a certain level of security to the communication and the reconfiguration of the system´s components. The proposed architecture uses FPGA boards and a microprocessor, the agent host, as components and is flexible and re-programmable.
