Abstract
Various embodiments of the invention provide for secure data communication in industrial process control architectures that employ a network of sensors and actuators. In various embodiments, data is secured by a secure serial transmission system that detects and authenticates IO-Link devices that are equipped with secure transceivers circuits, thereby, ensuring that non-trusted or non-qualified hardware is prevented from connecting to a network and potentially compromising system behavior.
