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.

“…For example, it is pretty easy to be implemented in software and hardware due to its simplicity. At present, RC4 algorithm can be applied in the areas of cloud computing, 15 voice cipher, 16 artificial intelligence, 17 and digital image transmission 18 . Software‐implemented RC4 cryptographic algorithm is widely applied in the areas of network security and information security due to its low computational complexity, fast encryption speed, and high security against malicious attacks.…”

“…It means that RC4 algorithm does not require any non‐linear transformation block to achieve the encryption. Accordingly, RC4 cipher is more robust than block ciphers under the presence of DPA attacks 15 . So as to further reinforce the robustness of RC4 algorithm against DPA attacks, pseudo‐random number generators (PRNGs) are embedded into the proposed RC4 architecture to randomize the corresponding dynamic power dissipation in real‐time.…”

In this letter, a high‐speed and low‐latency Ron Rivest‐4 (RC4) encryption algorithm is designed based on SMIC 14 nm process. Since the key issue of limiting the throughput of RC4 encryption algorithm is the swapping operation of S‐box, this proposed design is capable of achieving four swapping operations of S‐box within a clock cycle by utilizing fully combinational logic designs and advanced computations. All 256 swapping operations of key scheduling algorithm (KSA) can be done in 64 clock cycles. Moreover, the novel design greatly improves the encryption efficiency of RC4 since each clock cycle offers 4 bytes of key stream. The whole area can be further optimized by reusing the existing modules, and a lightweight countermeasure is embedded into the RC4 design to break the correlation between the processed data and power dissipation against differential power analysis (DPA) attacks. Finally, the whole design is assessed by the SMIC 14 nm process design kits (PDK). The corresponding clock frequency, throughput, area, and latency, respectively, are achieved as 1 GHz, 32 Gbps, 51,596 m2, and 74 clock cycles.

Cryptography and Steganography are two main components of information security. Utilizing encryption and Steganography to establish many layers of protection is a commendable approach. Our main objective of this paper is to build an integrated method of securely transmitting data through a combination of cryptography and Steganography. Cryptography and Steganography are two common methods of secretly transmitting information. RC4 is used in this paper to change information from plaintext to cipher, and then cipher text is integrated into the image by Least Significant Bit (LSB). The results are defined in terms of the processing time, the peak signal-to-noise ratio (PSNR), and mean square error (MSE). The experimental results showed the stego image’s acceptable quality and combining the two techniques provides additional security in the original Steganography.
