In the rapidly evolving domain of the Internet of Things (IoT) and fog computing, maintaining security, scalability, and efficient operation poses significant challenges. Addressing these issues, this study introduces "BlockFog," a novel blockchain-based framework designed to bolster intrusion defense in IoT fog computing environments. The core objective of BlockFog is to counteract the vulnerabilities inherent in decentralized IoT ecosystems by leveraging blockchain technology for enhanced security and transparency. The framework's innovative design integrates crucial components such as Device Onboarding & Identity Management, Data Integrity & Logging, Smart Contract-Driven Intrusion Detection, Automated Blockchain Responses, Secure Peer-to-Peer Communication, and a Lightweight Consensus Mechanism. These elements work collectively to ensure the security and functionality of IoT devices within the fog computing paradigm. BlockFog stands out for its meticulous approach to handling high transaction volumes with off-chain computations and layer-2 solutions, ensuring data integrity and facilitating seamless audit processes. The framework's resilience is further demonstrated through its robust response to evolving cyber threats, incorporating Over-the-Air (OTA) updates and advanced data protection mechanisms like zero-knowledge proofs. A comparative analysis highlights BlockFog's superior performance against existing models. The results reveal BlockFog's lower latency rates in normal, high traffic, and attack scenarios, its higher throughput efficiency, and its more effective resource utilization in terms of CPU, memory, and bandwidth usage. Moreover, BlockFog exhibits an enhanced ability to detect and respond to malicious activities, including DDoS attacks, with significantly higher accuracy than its counterparts. These findings underscore BlockFog's potential in redefining security and operational paradigms in IoT fog computing, making it a robust, agile, and transparent framework suitable for the current digital landscape.

“…Robles et al [38] combined the building features of blockchain technology to initiate and utilize a customer-focused data management system in AMI. Since blockchain is a decentralized public digital ledger for recording transactions that cannot be changed without changing all the subsequent blocks and the consensus of the network, access control, integrity, and authentication of the involved data were therefore guaranteed via blockchain [39,40] PUFs get easily denatured/altered in the presence of extreme temperatures [27] 2…”

The traditional electrical grid has to be digitally improved as digitalization and effective integration of renewable energy bring better efficiency, intelligence, and safety into the grid; hence, the transition from the traditional grid to a smart grid. A smart grid is a modernized and digitalized standard electrical infrastructure that has a key component known as the advanced metering infrastructure (AMI). AMI, also known as smart metering, is a key technological enabler of the smart grid that allows automatic collection and reporting of power-consumed data via two-way communication networks. However, the collected power consumption data is confidential; hence, its privacy must be maintained. Similarly, for the benefit of the smart grid to be consistently maximized, the AMI data and network security must always be intact despite the evolving threats and attacks targeted at it.This paper provides a comprehensive review of the existing vulnerabilities/attacks, security and privacy challenges associated with the smart metering data and network system, its open issues, and future direction. The major contributions of this review paper lie in the AMI vulnerabilities, AMI state-of-the-art security schemes with their pros and cons, its communication protocols analysis, and its emerging security measures. This gave enumerated recommendations for the efficiency improvement of AMI security in terms of its latency reduction while implementing efficient security measures in its future work.

Smartphones are essential tools for everyday tasks and are widely used for a multitude of communication services. Services such as video streaming, content sharing or instant messaging require users to have an internet connection in order to connect to a central server. However, in out-of-coverage areas such as the mountains or in areas where the infrastructure is damaged, phones are unable to establish a connection to the server. As a consequence, these services become unavailable. This can be critical during natural disasters and rescue operations where user's connectivity can make a significant difference.In out-of-coverage areas, smartphones equipped with Wi-Fi radio may make use of the radio to establish a Peer-to-Peer (P2P) network with other users in the vicinity. This would then enable users to communicate through the established network. However, unlike ordinary Wi-Fi settings that use a dedicated Wi-Fi base station, in a P2P setting every device has the opportunity to assume this master role and the communication has to be adjusted accordingly. To achieve this, other Wi-Fi technologies, such as Wi-Fi Direct and Wi-Fi Aware, are needed.The P2P approach also presents new challenges in several aspects of security due to a lack of connection to a central server. In particular, the authentication of users is essential to ensure the identity of the communicating parties. Besides, users want to make sure they are not talking to an imposter and that their messages are not read or tampered with in the process. Thus, the main challenges are how to provide authentication of users and how to ensure the integrity and confidentiality of messages in internet-isolated P2P network.The goal of the master thesis is to design, implement and validate a solution for instant messaging when there is no internet connection. The proposed solution will enable secure and mutually authenticated communication among a group of devices in the vicinity. While Wi-Fi Aware will be used as the communication technology, an investigation that compares our solution with other related solutions will also be performed. In order to validate the solution experimentally, a proof-of-concept instant messaging application will be developed.
