The real-time communications in the "Smart-Grids" requires that the Intelligent Electronic Devices (IEDs) and network elements introduced minimum delay, and in turn have mechanisms for efficient computing. Previous algorithms based on SHA are not suitable for the high cost in terms of resources and the latency introduced. Therefore, this project will focus on the development of algorithms implemented in FPGAs to provide cyber security functions to communication messages, enabling low latency, flexibility and scalability to meet the stringent latency requirements contained in the various regulations of the electrical sector. Because these new networks are subject to attacks from general communication networks, one form of defense is to follow the same protocols and standards that exist for such networks and adapt them to the particularities of the smart-grids.
