With the rapid development of network and communication technology, the interaction of various information data is more and more frequent, and people pay more and more attention to information security. The information encryption algorithm is a research hotspot in the field of information security. The Advanced Encryption Standard (AES) algorithm has been widely used in the field of information security with its high security and encryption efficiency. This paper mainly introduces the optimization of the AES-128 encryption algorithm of the security layer in ZigBee networking of the Internet of Things. By analyzing the principles of ZigBee networking and the AES encryption algorithm, the changes are optimized. In this paper, the new S-box cryptographic properties are used after analysis and calculation. The affine transformation period, the number of iteration cycles, and the algebraic expression of the S-box are improved. Its cryptographic properties are better than the S-box of the original algorithm, and the security of the algorithm is improved. In the theory of column hybrid algorithm, the computational complexity is reduced by changing the fixed polynomial, and the efficiency of the column hybrid algorithm is improved. In this paper, the performance of the improved AES algorithm is tested. The results show that, in the power consumption curve experiment, the recovery success rate of the original algorithm is about 42%, and the recovery success rate of the improved algorithm is nearly 60%. The improved algorithm is faster than the original algorithm in achieving a recovery success rate of 100%. Experimental results show that the design can accurately complete the encryption and decryption of the AES algorithm, and the performance is better than the original algorithm, which proves the overall superiority of the algorithm.

“…Here, the statistical test qualified Salp swarm guided fittest 128 bit long weighted vector act as a key for the AES-128 algorithm. In a classical AES algorithm (Karthigaikumar et al 2015 ), a randomly chosen 128 bit AES key may not qualified for all statistical tests. So, generation of robust key for AES is always an issue.…”

The outbreak of novel corona virus had led the entire world to make severe changes. A secured healthcare data transmission has been proposed through Telecare Medical Information System (TMIS) based on metaheuristic salp swarm. Patients need proper medical remote treatments in this Post-COVID-19 time from their quarantines. Secured transmission of medical data is a significant challenge of digitally overwhelmed environment. The objective is to impart the patients’ data by encryption with confidentiality and integrity. Eavesdroppers can carry sniffing and spoofing in order to deluge the data. In this paper, a novel scheme on metaheuristic salp swarm based intelligence has been sculptured to encrypt electrocardiograms (ECG) for data privacy. Metaheuristic approach has been blended in cryptographic engineering to address the TMIS security issues. Session key has been derived from the weight vector of the fittest salp from the salp population. The exploration and exploitation control the movements of the salps. The proposed technique baffles the eavesdroppers by the key strength and other robustness factors. The results, thus obtained, were compared with some existing classical techniques with benchmark results. The proposed MSE and RMSE were 28,967.85, and 81.17 respectively. The time needed to decode 128 bits proposed session key was 8.66 × 10 52 years. The proposed cryptographic time was 8.8 s.

“…In [20] the architecture for both encryption and decryption using AES is designed by incorporating folded architecture with parallel architecture to increase the throughput and reduce the power consumption. In [21] a parallel sub-pipelined architecture is introduced for AES algorithm. The area of architecture was minimized by combining techniques such as order change, composite field arithmetic (CFA) and key expansion.…”

Advanced Encryption Standard (AES) is a thriving cryptographic algorithm that can be utilized to guarantee security in electronic information. It remains to uphold to be resistive from most of the attacks. In this work, AES-128 encryption iterative architecture is designed to achieve minimum area and less hardware utilization. Reduced area is attained by introducing a renovated S-box structure into the AES algorithm. Furthermore, hardware utilization is minimized by incorporating the Vedic multiplier in the Mix column transformation of the AES Encryption process. The proposed encryption architecture is of 128-bit size and was executed on the Xilinx Spartan FPGA series, namely, Spartan 3, Virtex-4 and Virtex-5 devices. The optimization result exhibits that the proposed S-box technique has a smaller area than other existing conventional works.
