IMPLEMENTATION OF DATA ENCRYPTION AND DECRYPTION USING RSA(RIVEST-SHAMIR-ADLEMAN) ALGORITHM FOR WAN/LAN CHANNELS
Abstract:
Background: With the pervasive growth of digital communication and data exchange over Wide Area Networks (WAN) and Local Area Networks (LAN), the security of transmitted information becomes paramount. The RSA (Rivest-Shamir-Adleman) algorithm, a widely adopted public-key cryptosystem, offers a robust solution for secure data transmission through its principles of asymmetric encryption. This study focuses on the implementation of the RSA algorithm to secure data communication over both WAN and LAN channels, aiming to enhance the confidentiality and integrity of sensitive information.
Methods: The implementation involved the development of encryption and decryption modules based on the RSA algorithm. A secure key exchange mechanism was established for secure communication between parties. The study utilized real-world network scenarios, simulating WAN and LAN environments to evaluate the algorithm’s performance in terms of computational efficiency, data integrity, and resistance against potential cyber threats.
Results: The implementation demonstrated successful encryption and decryption processes using the RSA algorithm for both WAN and LAN channels. The computational overhead, key generation times, and encryption/decryption speeds were assessed, providing insights into the algorithm’s feasibility for real-time data transmission. The study also evaluated the resilience of the RSA algorithm against common cryptographic attacks, affirming its robustness in maintaining data security.
Conclusion: The successful implementation of the RSA algorithm for data encryption and decryption in WAN and LAN channels underscores its efficacy in securing digital communication. The findings highlight the algorithm’s versatility, offering a viable solution for diverse networking environments. As digital threats continue to evolve, the RSA algorithm’s adaptability and resistance to attacks position it as a valuable tool for safeguarding sensitive information in contemporary networked systems. Further research may explore optimizations and integrations with emerging technologies to ensure the continued relevance and effectiveness of the RSA algorithm in evolving cybersecurity landscapes.
