A Selective Encryption for Heterogenous Color JPEG Images Based on VLC and AES Stream Cipher

Abstract : Nowadays, the most important engine to provide confidentiality is encryption. Therefore, the classical and modern ciphers are not suitable for huge quantity of data in real-time environment. Selective encryption (SE) is an approach to encode only the most important portion of the data in order to provide a proportional privacy and to reduce computational requirements. The objective of our work is to leave free the low-resolution image and give full-resolution access only for authorized person. This approach is based on AES stream ciphering using VLC (Variable Length Coding) of the Huffman's vector. The proposed scheme allows decryption of a specific region of image and result in a significant reduction in encrypting and decrypting processing time. It also provides a constant bit rate and keep the JPEG bit-stream compliance. We have illustrated our method on a digital painting of the Louvre Museum of Paris, France.
