A Dual-Layer Approach: Combining Lightweight and Dynamic RSA for Enhanced Data Security

An important aspect for both individuals and business data is security. Security has been studied extensively by many researchers. Security gaps or threats are ever increasing, and data protection is a primary issue. A lightweight hybrid cryptographic algorithm with two layers of encryption has been presented in this paper. A new effective, lightweight algorithm named ASCON-128 is used in the first layer, and a dynamic version of RSA (Rivest-Shamir-Adleman) is used in the second layer. Asymmetric and symmetric cryptographic features have been combined by this approach. The proposed algorithm’s performance was evaluated using metrics such as execution time, throughput rate, delay, and latency. A higher level of security, a faster encryption execution times, reduced memory usages, and improved throughput were observed in the proposed algorithm when compared to widely used cryptographic systems. The resultsare shown by the experimental findings.
