Abstract:	In the modern era, the issues pertaining with secured, fast and efficient image transmission with limited bandwidth are challenging task. This provides a platform to the researcher to work on image compression-encryption (CE) methodologies. To influence the degree of compression, this paper presents a DCT based compression algorithm using luminous quantization followed by advanced encryption standard (AES) and data encryption standard (DES) encryption methods. In this paper, the effect of encryption over compressed image in terms of PSNR and SSIM is analysed. Efficiency of the AES and DES encryption algorithms are compared based on key space, histogram and differential analysis. The experiment is performed on five different test images. From the results, it is observed that DCT-AES combination of compression-encryption algorithms gives higher resistance to redundant data and provides better security to information during transmission.
