Image Transaction Encryption Based on a Dynamic Upswing of Hill Cipher and JPEG Compression

Faiq GMIRA, Said HRAOUI, Wafae SABBAR, Abderrahmane JARRAR OULIDI

Abstract



In this article, first a robust dynamic upswing of Hill-Cipher encryption is developed. After that, this new dynamic encryption is optimally integrated in the structure of a coding based on JPEG compression. Given that the JPEG file format is supported by every image editor and all web browser; our method is multi-platform and universal. The effectiveness and robustness of our scheme is validated by measuring its security strength, its Throughput, its computational cost and the quality of reconstructed images.
