A Comparative Analysis for Sustainable Cybersecurity Solutions on Improving Image Security via Hybrid, Symmetric, and Asymmetric Encryption

Resumo

The study suggests a new method for encrypting and securing images called the hybrid algorithm, which combines symmetric and asymmetric techniques, and compares it with AES, RSA, and other encryption algorithms. Five high-resolution grayscale photos of different sizes were used for encryption and decryption. The images were encrypted using AES, RSA, and hybrid algorithms. Performance analysis criteria like entropy, PSNR, correlation coefficient, and elapsed time were used to evaluate the algorithms' performance. Python was used for programming all simulation algorithms and criteria.

finding that hybrid encryption outperforms AES and RSA in terms of image size, strength, and encryption quality. It also outperforms RSA in PSNR and elapsed time for total encryption and decryption. The hybrid algorithm is 2% faster and has the lowest entropy value, making it resistant to statistical attacks. It has been discovered that the combination of symmetric and asymmetric encryption techniques creates a highly efficient algorithm for data security.
