| Abstract | ||||
| In the ever-evolving landscape of data security, the need for robust encryption mechanisms remains paramount. This paper introduces a novel concatenated encryption system that leverages the strengths of both the Data Encryption Standard (DES) and the Advanced Encryption Standard (AES). The proposed system sequentially applies DES and AES to plaintext data, combining the legacy robustness of DES with the modern security features of AES. This dual-layer encryption aims to enhance overall security, particularly against emerging cryptanalytic techniques. The concatenated DES-AES encryption system is evaluated for its security efficacy, computational performance, and practical applicability. The security analysis demonstrates that the dual encryption approach provides increased resistance to brute-force attacks and sophisticated cryptanalysis by leveraging the distinct encryption strengths of DES and AES. Additionally, the system benefits from AES's enhanced security features while utilizing DES's well-understood cryptographic foundation. However, the proposed system is not without its drawbacks. The primary disadvantage is the increased computational overhead due to the sequential application of two encryption algorithms. This results in a higher processing time compared to using a single encryption standard. Furthermore, while the concatenated approach increases security, it does not address the inherent vulnerabilities of DES, such as its susceptibility to brute-force attacks when used alone. The system's performance impact and complexity in implementation must be carefully considered in its deployment. The FPGA implementation will be presented in this paper to validate the concept of this paper. | ||||
