In today's society, which is heavily influenced by technology, it is crucial to prioritize the security and integrity of computer systems and their underlying hardware components. As advancements in hardware technologies continue to progress rapidly, new vulnerabilities emerge, posing significant risks to the confidentiality and integrity of sensitive information. Therefore, it is essential to proactively identify and mitigate potential threats to hardware. Traditionally, threat modeling tools have primarily focused on software vulnerabilities, neglecting the exploration of hardware vulnerabilities. However, with the increasing complexity of hardware architectures, there is an urgent need for effective methodologies to assess and address potential threats at the hardware level. Currently, state-of-the-art approaches in hardware threat modeling rely on static analysis techniques and knowledge of known hardware vulnerabilities. The existing approaches are considered cumbersome since they require computer validation experts and engineers to perform manual inspection, simulationbased testing, and formal verification. These approaches face increasingly difficult challenges these days when hardware architectures continuously evolve, rendering them more advanced and complicated. In order to cope with these challenges, it is therefore essential to seek alternative and more reliable approaches that are capable of improving the efficacy and accuracy of threat identification and analysis. Since generative Artificial Intelligence (AI) is equipped with the tool to model and generate complex data patterns, it can be considered an alternative approach for hardware threat modeling. With the aid of generative AI, the restricted scope faced by threat modeling can, therefore, be expanded. By incorporating generative AI into hardware threat modeling, hardware vulnerabilities that are hard to be detected and analyzed by conventional approaches can be identified. Hence, the overall security and integrity of computer systems can also be significantly enhanced, resulting in the formation of a more secure environment for protecting sensitive information.

Agriculture 4.0 is evolving by combining traditional farming methods with advanced technologies from Industry 4.0, offering farmers new opportunities to improve their agricultural practices. However, implementing Agriculture 4.0 through the incorporation of these innovative technologies and evidence-based strategies is facing challenges. Moreover, data is proven as one of the most significant assets in the era of big data. Analyzing massively distributed agricultural data while ensuring its privacy, security, and scalability concerns is also an important challenge. This chapter presents the state-of-the-art by leveraging the applications of federated learning methods to handle the aforementioned challenges and promote collaborative analysis of distributed agricultural data. In this work, we utilize the publicly accessible Rice Dataset Cammeo and Osmancik, which comprises 3,810 instances, with 2180 instances of Osmancik and 1,630 instances of Cammeo. This study presents a federated learningbased rice variety classification (AgriFedClassifier) framework for analyzing distributed agricultural data while safeguarding the privacy and security of clients’ local data. We simulate the framework with Multilayer Perceptron models at each client, training the models for a fixed number of local epochs using local data and aggregating model updates at the server employing Federated Averaging (FedAvg) and Federated Proximal (FedProx) methods. We evaluate the effectiveness of federated learning techniques on horizontally distributed agricultural data under two scenarios: IID and non-IID datasets. Experimental results demonstrate that in non-IID data distributions with 80% of stragglers (nodes encountering delays), FedProx achieved a classification accuracy of 89.33%, whereas FedAvg achieved only 50% accuracy. The results section presents an analysis of the effectiveness of federated and centralized models. Overall, we observe that FedProx effectively managed data heterogeneity, mitigated delays, and improved efficiency compared to FedAvg.
