Abstract: In the environment of Cloud-CCTV surveillance, encryption of images for the protection of privacy is essential. Yet, the existing encryption method has overhead regarding the management of mass data and streaming processing. As encrypted vectors are created and applied in a bucket unit in the proposed method, it has more efficient performance in the process of encryption and decoding compared to AES-CTR mode, and it makes an analysis attack difficult according to the randomness of a bucket size. In this paper, AES-GCTR mode that has improved the existing AES-CTR operation mode was suggested. In this process, encryption of CCTV image data is required. Yet, overhead of encryption itself exists in quality, so an efficient encryption method proper for mass data is necessary. The proposed method can make encryption and decoding performance more efficient, and is expected to be easily applied to the image surveillance system based on CCTVs that demands high capacity processing and real-time streaming.
