System and method for converting serial data into secure data packets configured for wireless transmission in a power system

摘要

Provided is a system and method for converting serial data associated with an IED into secure data packets configured for transmission during an IED maintenance session; preferably wireless transmission. The system includes a first intelligent assembly operatively coupled to the IED, and a second intelligent assembly operatively coupled to the first intelligent device via a wireless communication link. Each of the first and second intelligent assemblies includes a microcontroller adapted to apply two independent security algorithms to the serial data to form the secure data packets, and vice versa. The second intelligent assembly further includes a plurality of legacy software applications executable to enable the IED maintenance session to be conducted by an operator from a location of the second intelligent assembly. The security algorithms preferably include an AES encryption/decryption function and a HMAC authentication function.
