An Integrated Cryptographic Approach Using Elliptic Curve Cryptography, Triple Data Encryption Standard and Hash-based Message Authentication Code.

Security of digital communication becomes of prime importance due to the fast growing cybersecurity attacks. Classical encryption algorithms frequently drop down in offering the vital level of security required to safeguard critical information. The advances in cryptography methods are very important to solve this issue and ensure integrity and privacy. This paper focuses on the weaknesses of the current methods through investigating mixing multiple encryption methods. The research explores whether combining Hash-based Message Authentication Code (HMAC), Elliptic Curve Cryptography (ECC), and Triple Data Encryption Standard (3DES) can provide upgrade to security for end-to-end encryption. The chief objective is to improve and evaluate a powerful encryption framework that make use the strengths of HMAC, ECC and 3DES. This is done by showing how mixing these algorithms together can improve security and reliability levels to safeguard digital communications. An extensive analysis is performed by using several metrics. These involve ciphering and deciphering speed, key generation, NIST test and Avalanche effect. The results show that these combinations increase significantly security level of digital communication. It shows better performance than traditional cryptography in both security and speed. Combining HMAC, ECC and 3DES provide practical solution to increase security level in end-to- end encryption. It improves the vulnerabilities in traditional cryptography by building multi-layer security framework. It is concluded that the proposed framework is powerful and a candidate for developing and has strong resistance against cyber threats. [ABSTRACT FROM AUTHOR]
