Abstract

This invention discloses a method for authenticating messages in an industrial control system environment where several resource-constrained industrial controllers interact with various entities. Messages are authenticated by concatenating the original message with a tag, generated with the use of a shared secret key between the sender and receiver. This architecture achieves the goals of integrity and availability by using Message Authentication Codes, which are chosen keeping the metrics of speed and security in focus. Further, Replay attacks and Denial of Service attacks are circumvented by using the method and architecture of the present invention
