DIAT: Data Integrity Attestation for Resilient Collaboration of Autonomous Systems

Abstract

Networks of autonomous collaborative embedded systems are emerging in many application domains such as vehicular ad-hoc networks, robotic factory workers, search/rescue robots, delivery and search drones. To perform their collaborative tasks the involved devices exchange various types of information such as sensor data, status information, and commands. For the correct operation of these complex systems each device must be able to verify that the data coming from other devices is correct and has not been maliciously altered.
