Hybrid Fuzzy Rule Algorithm and Trust Planning Mechanism for Robust Trust Management in IoT-Embedded Systems Integration

The Internet of Things (IoT) is rapidly expanding and becoming an integral part of daily life, increasing the potential for security threats such as malware or cyberattacks. Many embedded systems (ESs), responsible for handling sensitive data or facilitating secure online activities, must adhere to stringent security standards. For instance, payment processors employ security-critical components as distinct chips, maintaining physical separation from other network components to prevent the leakage of sensitive information such as cryptographic keys. Establishing a trusted environment in IoT and ESs, where interactions are based on the trust model of communication nodes, is a viable approach to enhance security in IoT and ESs. Although trust management (TM) has been extensively studied in distributed networks, IoT, and ESs, significant challenges remain for real-world implementation. In response, we propose a hybrid fuzzy rule algorithm (FRA) and trust planning mechanism (TPM), denoted FRA + TPM, for effective trust management and to bolster IoT and ESs reliability. The proposed system was evaluated against several conventional methods, yielding promising results: trust prediction accuracy (99%), energy consumption (53%), malicious node detection (98%), computation time (61 s), latency (1.7 ms), and throughput (9 Mbps).

Combined Reliability Testing Profile Model and Application for Embedded System

Embedded system is applied more and more extensively in the fields of national defense weapon equipment. With the increasing complexity of embedded systems, the combination of the hardware with software is more and closer. Because of the overall characteristic of hardware and software combination in embedded system, traditional reliability test can hardly accurately identify the reliability of embedded systems. The proposed combined reliability testing method, which combines software reliability test with system integrated environmental stress test to simulate the state of system running, provides the basis for the accurate validation and evaluation of reliability of embedded system.

Hybrid Simulation Based Approach for Embedded Systems Reliability Analysis

This paper describes a reliability approach based on a coupling of discrete and continuous dynamics simulation of embedded systems. This hybrid simulation is a combination in the same formalism of the discrete simulation of an algorithm allowing the extraction of feared scenarios that lead an embedded system to a critical situation without generating the associated reachability graph in order to avoid the eternal combinative explosion problem, and, the continuous dynamics of the embedded system represented by a Java code. The simulation of discrete and continuous dynamics is coupled in object-oriented stopwatch Petri net models that allow the representation of the suspension and resumption of task execution.
