Abstract
The present invention is a method and system for high-assurance data tagging for input/output feeds. The method may include executing a high-assurance tagging application on a microprocessor (e.g., the microprocessor being designed for use in a high-assurance embedded system). Further, the method may include analyzing a message with the high-assurance tagging application and generating and attaching a tag to the message. In addition, the method may include binding the tag to the message by applying a message authentication scheme and providing a mechanism for down-stream applications to identify information about data included in the message by reference to the tag.
