A Method for Securing Symmetric Keys for Internet of Things Enabled Distributed Data Systems

This study introduces an innovative method for securing symmetric keys in Internet of Things (IoT)-enabled distributed data systems, focusing on enhancing data security while optimizing encryption and decryption times. Through a comprehensive analysis of various encryption algorithms—TEA, XTEA, BLOCK TEA (XXTEA), and the proposed NTSA algorithm—across different key sizes and file sizes, we aim to demonstrate the significant improvements our method offers over existing techniques. Our research meticulously evaluated the performance of these algorithms, employing random variations to encryption and decryption times to simulate real-world variability and assess the algorithms' efficiency and security robustness. The findings reveal that the NTSA algorithm, in particular, showcases superior performance, offering an approximate improvement of 10% to 15% in encryption and decryption times over traditional methods such as TEA and XTEA, and an even more considerable enhancement compared to BLOCK TEA (XXTEA). The key contribution of this study lies in its provision of a secure, efficient framework for symmetric key encryption in IoT-enabled distributed environments. By optimizing key size and algorithm selection, our method not only secures data against potential cyber threats but also ensures high-speed data processing—a critical requirement in the IoT domain where the volume of data transactions and the need for real-time processing are ever-increasing. The proposed method significantly advances the field of data security in distributed systems, especially within the context of the burgeoning IoT landscape. It underscores the importance of algorithmic efficiency and strategic key management in bolstering the security and performance of modern digital ecosystems

Octopus++: an enhanced mutual authentication security protocol and lightweight encryption and decryption algorithm based on DNA in fog computing

The Internet of Things (IoT) envisions a world wherein everyday objects may connect to the internet and exchange data, analyse, store, and gather data from their environment and efficiently mediate on it. Fog computing, closer to the IoT, is formulated in data processing, filtering, aggregating, and storing. In fog IoT network one of the main challenges is security. The existing security solutions are based on modern cryptography algorithms are computationally complex which causes the fog IoT network to slow down. Therefore, in fog IoT the operations must be lightweight and secure. The security considerations include attacks, especially Man in the Middle attack (MitM), challenges, requirements, and existing solutions that are deeply analyzed and reviewed. Hence, omega network key generation based on deoxyribonucleic acid (ONDNA) is proposed, which provides lightweight encryption and decryption in fog computing. The security level of ONDNA is tested using NIST test suite. ONDNA passes all the 17 recommended NIST Test Suite tests. Next, we proposed a modified security protocol based on ONDNA and hash message authentication code with secure hash algorithm 2. The modified protocol is noted as OCTOPUS++. We proved that the OCTOPUS++ provides confidentiality, mutual authentication, and resistance to MitM attack using the widely accepted Burrows Abdi Needham (BAN) logic. The OCTOPUS++ is evaluated in terms of execution time. The average execution time for 20-time execution of OCTOPUS++ is 1.018917 milliseconds. The average execution time for Octopus, LAMAS and Amor is 2.444324, 20.1638 and 14.1152 milliseconds respectively. The results show that the OCTOPUS++ has less execution time than other existing protocol

Strategies to Protect Against Security Violations During the Adoption of the Internet of Things by Manufacturers

Security violations have been one of the key factors affecting manufacturers in adopting the Internet of Things (IoT). The corporate-level information technology (IT) leaders in the manufacturing industry encounter issues when adopting IoT due to security concerns because they lack strategies to protect against security violations. Grounded in Roger’s diffusion of innovations theory, the purpose of this qualitative multiple case study was to explore strategies corporate-level IT leaders use in protecting against security violations while adopting IoT for manufacturers. The participants were senior IT leaders in the eastern region of the United States. The data collection process included interviews with corporate-level IT leaders (n = 6) and examination of company documents (n = 10). The data analysis process involved searching patterns for words, codes, or themes and their relationships to confirm the findings. During analysis, four major themes emerged: relevance of securing IoT devices in IoT adoption, identifying and separating personal and confidential data from analytical data, adequate budget for securing IoT network devices and infrastructure as key factors in IoT adoption, and risk mitigation policy relevant to securing IoT devices. The implications for positive social change include the potential for corporate-level IT leaders to develop tools that will detect threats, prevent malicious attacks, and monitor IoT networks for any IoT device vulnerabilities. Improved protection from security violations may result in more efficient ways for people to use natural resources. Additionally, there may be a wider usage of smartphones connected to IoT to simplify people’s lives
