Secure Sensor Prototype Using Hardware Security Modules and Trusted Execution Environments in a Blockchain Application: Wine Logistic Use Case
The security of Industrial Internet of Things (IIoT) systems is a challenge that needs to be
addressed immediately, as the increasing use of new communication paradigms and the abundant
use of sensors opens up new opportunities to compromise these types of systems. In this sense,
technologies such as Trusted Execution Environments (TEEs) and Hardware Security Modules
(HSMs) become crucial for adding new layers of security to IIoT systems, especially to edge nodes
that incorporate sensors and perform continuous measurements. These technologies, coupled with
new communication paradigms such as Blockchain, offer a high reliability, robustness and good
interoperability between them. This paper proposes the design of a secure sensor incorporating
the above mentioned technologies—HSMs and a TEE—in a hardware device based on a dual-core
architecture. Through this combination of technologies, one of the cores collects the data extracted by
the sensors and implements the security mechanisms to guarantee the integrity of these data, while
the remaining core is responsible for sending these data through the appropriate communication
protocol. This proposed approach fits into the Blockchain networks, which act as an Oracle. Finally,
to illustrate the application of this concept, a use case applied to wine logistics is described, where
this secure sensor is integrated into a Blockchain that collects data from the storage and transport of
barrels, and a performance evaluation of the implemented prototype is providedEuropean Union’s Horizon Europe research and innovation program through the funding project

Assessing Hardware Security Threats Posed by Hardware Trojans in Power Electronics
This study investigates the threat of hardware Trojans (HTs) in power electronics applications, a rising concern due to the growing demand for cost-effective embedded solutions in power systems. With the supply chain for electronic hardware devices expanding globally, particularly to low-cost foundries in foreign locations, there is an increasing risk of HT attacks. While there has been extensive research on HTs in computer applications, little consideration has been given to their threat in power electronics. This study demonstrates the effectiveness of a power electronics HT by implementing a novel HT design into a gate drive circuit. Additionally, the research proposes several HT designs that exploit factors unique to power circuits, such as high power delivery and analog circuitry in order to illustrate the distinct attack space. The research highlights the need for enhanced detection, protection, and prevention methods in power electronics applications and offers a roadmap for future studies to develop more effective countermeasures and algorithms to mitigate the risks of HT attacks in power electronics
Blockchain-enhanced Roots-of-Trust
Establishing a root-of-trust is a key early step in establishing trust throughout the lifecycle of a device, notably by attesting the running software. A key technique is to use hardware security in the form of specialised modules or
hardware functions such as TPMs. However, even if a device supports such features, other steps exist that can compromise the overall trust model between devices being manufactured until decommissioning. In this paper, we discuss how blockchains, and smart contracts in particular, can be used to harden the overall security management both in the case of existing hardware enhanced security or when only software attestation is possible
Internet of robotic things : converging sensing/actuating, hypoconnectivity, artificial intelligence and IoT Platforms
The Internet of Things (IoT) concept is evolving rapidly and influencing newdevelopments in various application domains, such as the Internet of MobileThings (IoMT), Autonomous Internet of Things (A-IoT), Autonomous Systemof Things (ASoT), Internet of Autonomous Things (IoAT), Internetof Things Clouds (IoT-C) and the Internet of Robotic Things (IoRT) etc.that are progressing/advancing by using IoT technology. The IoT influencerepresents new development and deployment challenges in different areassuch as seamless platform integration, context based cognitive network integration,new mobile sensor/actuator network paradigms, things identification(addressing, naming in IoT) and dynamic things discoverability and manyothers. The IoRT represents new convergence challenges and their need to be addressed, in one side the programmability and the communication ofmultiple heterogeneous mobile/autonomous/robotic things for cooperating,their coordination, configuration, exchange of information, security, safetyand protection. Developments in IoT heterogeneous parallel processing/communication and dynamic systems based on parallelism and concurrencyrequire new ideas for integrating the intelligent “devices”, collaborativerobots (COBOTS), into IoT applications. Dynamic maintainability, selfhealing,self-repair of resources, changing resource state, (re-) configurationand context based IoT systems for service implementation and integrationwith IoT network service composition are of paramount importance whennew “cognitive devices” are becoming active participants in IoT applications.This chapter aims to be an overview of the IoRT concept, technologies,architectures and applications and to provide a comprehensive coverage offuture challenges, developments and applications
