Thesis title: Security architecture for multi-embedded-agent systems

Abstract:

With the number of embedded devices ever-increasing and the rise of artificial intelligence that promotes interconnected autonomous systems, we are now overwhelmed with embedded systems gathering information and providing services ranging from home automation, to smart healthcare and autonomous transportation. Moreover, we are now reaching the limits of data centers and centralized architectures and are heading toward edge computing and decentralized systems. Both the increase in number and autonomy of these decentralized systems lead to more complexity but also to security vulnerabilities and threats. Those systems are prone to hardware, network and software attacks which might not only damage them, butalso expose personal and health information.This thesis aims to provide the foundations of a global security architecture capable of implementing countermeasures for all the attacks that decentralized networks of autonomous embedded devices can face.Thus, we plan to study and assemble current state-of-the-art advancements in security of decentralized autonomous systems. In order to achieve this goal, we reviewed the scientific literature regarding this topic; then, noticing a lack of key management systems to complete this security architecture, we proposed a public key infrastructure specifically designed for decentralized autonomous systems of embedded devices.The infrastructure was validated through simulations and model checking.We are now looking to enhance it using a distributed ledger to store the certificates and certificate revocation lists.
