“…In order to verify that information has not been tampered with in transit, the SHA-1 technique is used to generate a unique hash for each input. SHA-1 is widely used in IoT applications since it is fast and can generate a different hash for each input, and it is also significantly faster than its counterparts [188]. To verify that a message has not been tampered with, another technique called HMAC (Hash-based Message Authentication Code) is used, and it makes use of SHA-1.…”

The emergence of the Internet of Things (IoT) technology has brought about tremendous possibilities, but at the same time, it has opened up new vulnerabilities and attack vectors that could compromise the confidentiality, integrity, and availability of connected systems. Developing a secure IoT ecosystem is a daunting challenge that requires a systematic and holistic approach to identify and mitigate potential security threats. Cybersecurity research considerations play a critical role in this regard, as they provide the foundation for designing and implementing security measures that can address emerging risks. To achieve a secure IoT ecosystem, scientists and engineers must first define rigorous security specifications that serve as the foundation for developing secure devices, chipsets, and networks. Developing such specifications requires an interdisciplinary approach that involves multiple stakeholders, including cybersecurity experts, network architects, system designers, and domain experts. The primary challenge in IoT security is ensuring the system can defend against both known and unknown attacks. To date, the IoT research community has identified several key security concerns related to the architecture of IoT systems. These concerns include issues related to connectivity, communication, and management protocols. This research paper provides an all-inclusive and lucid review of the current state of anomalies and security concepts related to the IoT. We classify and analyze prevalent security distresses regarding IoT’s layered architecture, including connectivity, communication, and management protocols. We establish the foundation of IoT security by examining the current attacks, threats, and cutting-edge solutions. Furthermore, we set security goals that will serve as the benchmark for assessing whether a solution satisfies the specific IoT use cases.

In modern information technology systems, secure storage and transmission of personal and sensitive data are recognized as important tasks. These requirements are achieved through secure and robust encryption methods. Argon2 is an advanced cryptographic algorithm that emerged as the winner in the Password Hashing Competition (PHC), offering a concrete and secure measure. Argon2 also provides a secure mechanism against side-channel attacks and cracking attacks using parallel processing (e.g., GPU). In this paper, we analyze the existing GPU-based implementation of the Argon2 algorithm and further optimize the implementation by improving the performance of the hashing function during the computation process. The proposed method focuses on enhancing performance by distributing tasks between CPU and GPU units, reducing the data transfer cost for efficient GPU-based parallel processing. By shifting several stages from the CPU to the GPU, the data transfer cost is significantly reduced, resulting in faster processing times, particularly when handling a larger number of passwords and higher levels of parallelism. Additionally, we optimize the utilization of the GPU’s shared memory, which enhances memory access speed, especially in the computation of the hash value generation process. Furthermore, we leverage the parallel processing capabilities of the GPU to perform efficient brute-force attacks. By computing the H function on the GPU, the proposed implementation can generate initial blocks for multiple inputs in a single operation, making brute-force attacks in an efficient way. The proposed implementation outperforms existing methods, especially when processing a larger number of passwords and operating at higher levels of parallelism.

“…Because of its larger output length, SHA-512 is suitable for scenarios that require higher security, such as cryptographic applications and digital certificates. 8 SHA-256 and SHA-512 have higher bit-width message digests and high security but also take up more area. 9,10 As the design of the algorithm is mainly used in data comparison rather than data encryption, there is no need for high security; after all aspects of the comparison, the SHA-1 algorithm is more suitable than the other two; it has the smallest bit width and the simplest logic and does not ARTICLE pubs.aip.org/aip/adv require additional design to defend against collision attacks; thus, in terms of performance, power consumption, and area, this algorithm is far ahead of the other two SHA algorithms.…”

In order to make direct memory access (DMA) high-speed transmission while ensuring the security and integrity of data, the traditional Secure Hash Algorithm (SHA) is improved from the algorithm model and hardware architecture level by adopting the methods of data synchronization preprocessing and multi-block multi-output, and a dual-channel design with instant data comparison and data error correction functions adapted to high-speed DMA is achieved. The simulation results show that the maximum clock frequency of the DMA controller is 120 MHz and the throughput rate is up to 3.8 Gbps. The improved comparison channel can output the message summary at an interval of 0.56 μs, whereas the traditional algorithm needs to wait five times as long as the data handling time. The error correction channel also implements multi-block output and error block indexing. The results show that the improved dual-channel design based on the SHA algorithm can be highly adapted to DMA controllers and has good application prospects.
