An Efficient Privacy and Anonymity Setup on Hyperledger Fabric for Blockchain-Enabled Internet of Things (IoT) Devices

The rise in IoT (Internet of Things) devices poses a significant security challenge. Maintaining privacy and ensuring anonymity within the system is a sought-after feature with inevitable trade-offs, such as scalability and increased complexity, making it incredibly challenging to handle. To tackle this, we introduce our proposed work for managing IoT devices using Hyperledger Fabric. We integrated our system on the blockchain with a closed-circuit television (CCTV) security camera fixed at a rental property. The CCTV security camera redirects its feed whenever a new renter walks in. We have introduced the web token for authentication from the renter to the owner. Our contributions include an efficient framework architecture using key invalidation scenarios and token authentication, a novel chain code algorithm, and stealth addresses with modified ring signatures. We performed different analyses to show the system’s throughput and latency through stress testing. We have shown the significant advantages of the proposed architectures by comparing similar existing schemes. Our proposed scheme enhances the security of blockchain-enabled IoT devices and mitigates the single point of failure issue in the existing scheme, providing a robust and reliable solution. Our future work includes scaling it up to cater to the needs of the healthcare system.

Unveiling the core of IoT: comprehensive review on data security challenges and mitigation strategies

The Internet of Things (IoT) is a collection of devices such as sensors for collecting data, actuators that perform mechanical actions on the sensor's collected data, and gateways used as an interface for effective communication with the external world. The IoT has been successfully applied to various fields, from small households to large industries. The IoT environment consists of heterogeneous networks and billions of devices increasing daily, making the system more complex and this need for privacy and security of IoT devices become a major concern. The critical components of IoT are device identification, a large number of sensors, hardware operating systems, and IoT semantics and services. The layers of a core IoT application are presented in this paper with the protocols used in each layer. The security challenges at various IoT layers are unveiled in this review paper along with the existing mitigation strategies such as machine learning, deep learning, lightweight encryption techniques, and Intrusion Detection Systems (IDS) to overcome these security challenges and future scope. It has been concluded after doing an intensive review that Spoofing and Distributed Denial of Service (DDoS) attacks are two of the most common attacks in IoT applications. While spoofing tricks systems by impersonating devices, DDoS attacks flood IoT systems with traffic. IoT security is also compromised by other attacks, such as botnet attacks, man-in-middle attacks etc. which call for strong defenses including IDS framework, deep neural networks, and multifactor authentication system.

Classification of malware for security improvement in IoT using heuristic aided adaptive multi-scale and dilated ResneXt with gated recurrent unit

The rise of malware in the Internet of Things (IoT) realm exploits sensitive IoT devices that lead to extensive malicious attacks that pose a significant danger to the integrity of the Internet ecosystem. Addressing this threat effectively requires a robust system for classifying and attributing IoT malware, serving as vital initial steps toward implementing countermeasures for attack prevention and mitigation. So, in this work, a new malware classification technique using deep learning is developed for solving different kinds of malware in IoT. The required images for the malware classification process are gathered from online databases and given to the developed Adaptive Multi-scale and Dilated ResneXt with Gated Recurrent Unit (AMDR-GRU)-based malware classification process. Here, the last layer of the ResneXt is modified with GRU, and several parameters are optimized in the suggested AMDR-GRU model with the support of the designed Intensified Random Parameter-based Chameleon Swarm Algorithm (IRPCSA) to enhance the classification performance. Finally, the developed AMDR-GRU model offered the classified outcome and the obtained classification results are compared with different existing malware classification models to prove the effectiveness of the developed model over others. The developed model offered 99.59 % of precision. The result proved that the developed model is used to classify different malware without reverse engineering, binary code analysis, and feature engineering. Moreover, by effectively classifying malware, this technique can contribute to enhancing the security of IoT devices, protecting them from potential threats and vulnerabilities.

DICEguard: enhancing DICE security for IoT devices with periodic memory forensics

The number of Internet-of-Things (IoT) devices has been increasing rapidly every year. Most of these devices have access to important personal data such as health, daily activities, location, and finance. However, these devices have security problems since they have limited processing power and memory to implement complex security measures. Therefore, they possess weak authentication mechanisms and a lack of encryption. Additionally, there are no widely accepted standards for IoT security. Device Identifier Composition Engine (DICE) was proposed as a standard that enables adding a security layer to low-cost microcontrollers with minimal silicon overhead. However, previous studies show that DICE-based attestation is vulnerable to some remote attacks. In this study, we present a novel method called DICEguard to address the security problems of DICE. One of the key innovations of DICEguard is its incorporation of periodic memory forensics (PMF) technique, leveraging a hardware-based hash engine to detect and mitigate potential security breaches resulting from firmware vulnerabilities. DICEguard enhances the overall resilience of IoT devices against attacks by swiftly detecting alterations indicative of malicious activity through periodic calculation and comparison of firmware digests. Furthermore, DICEguard introduces a one-time programmable (OTP) memory component to safeguard critical security parameters, such as public keys used for signature verification, against tampering by adversaries. This ensures the integrity of essential security measures even in the face of sophisticated attacks. We implemented the enhanced DICE architecture using the open-source RISC-V platform Ibex and the mbedTLS library for cryptographic operations. We performed the hash operations required by DICE in a hardware-based manner on a commercial Field Programmable Gate Array (FPGA) platform rather than firmware, which is more vulnerable to attacks. Our test results show that with negligible area overhead to a standard microcontroller system, the proposed method can detect the simulated attacks.

A significant problem is developing a simple security mechanism suitable for resource-constrained IoT devices. Elliptic curve cryptography (ECC) is extensively utilized and well-suited for use in low-resource environments like smartphone devices. ECC utilizes short crypto keys with the same security strength as conventional cryptosystems, decreasing power consumption and enhancing device efficiency. This study comprehensively evaluates ECC data privacy and security techniques in IoT-based devices. The research also looked into other cryptography protocols that ECC may use to increase security and performance. The inclusion procedures were papers published between 2018 and 2023, written in English, and published in a peer-reviewed scholarly outlet. This research eventually reviewed 61 suitable publications in total. Compared to other cryptographic methods, the study discovered that ECC has received greater attention or is frequently employed in IoT-based systems. However, additional issues and concerns must be addressed, including efficient IoT device security, maintaining privacy, and device security against vulnerability assaults such as man-in-the-middle attacks. For the efficient security of the IoT-based system, an improved ECC-based algorithm should be developed to enhance the security and privacy issues of the IoT system.

Addressing security challenges in industry 4.0: AVA-MA approach for strengthening SDN-IoT network security

In the context of Industry 4.0, the convergence of the Internet of Things (IoT) and Software Defined Networking (SDN) represents a challenging yet pivotal avenue for bolstering network security. This amalgamation facilitates the establishment of an integrated SDN-IoT platform that adeptly confronts the security intricacies arising from the evolving landscape of interconnected devices and industrial networks. Through the strategic application of SDN, the network architecture undergoes dynamic segmentation, responsive to diverse parameters encompassing device attributes, application contexts, and security imperatives. This segmentation strategy effectively isolates IoT devices, constricting the potential attack surface and correspondingly diminishing the ramifications of security breaches.

In this study, samples are collected and used from both the TON-IoT dataset and the SDN dataset to determine the effectiveness of the proposed AVA-MA method. The evaluation measures such as AUC, F1-score, recall, accuracy, and precision are used to evaluate the performance of the proposed AVA-MA method. The results depict the AVA-MA method attained an accuracy of 98.95 %, precision of 97.54 %, recall of 95.64 %, and F1-score of 98.86 % respectively.
