Abstract

In an era where data security remains paramount, modern cryptographic systems are essential to safeguarding sensitive information. The Elliptical Advanced Encryption Standard (E-AES) is a cutting-edge approach that leverages the strengths of traditional AES and elliptic curve cryptography (ECC). While AES is celebrated for its robust encryption capabilities, it suffers from increased computational overhead in resource-constrained environments. Similarly, ECC offers lightweight encryption with high security but faces challenges with scalability and data throughput. Combining these methodologies addresses these limitations, creating a hybrid algorithm that achieves both efficiency and security. The proposed E-AES employs elliptic curve-based key exchange for secure, lightweight key distribution, coupled with AES for high-throughput data encryption. Experimental evaluations demonstrate a significant reduction in encryption time (15%) and decryption time (18%), alongside enhanced security with an average entropy score of 7.96 out of 8, compared to traditional AES systems. The approach also reduces computational overhead by 20%, making it suitable for resource-limited applications like IoT and mobile devices. This hybrid encryption algorithm ensures secure communication by mitigating potential vulnerabilities associated with single-algorithm systems. E-AES thus represents a robust, scalable, and computationally efficient solution for modern secure data communication systems.
