Video Encryption Algorithm and Key Management using Perfect Shuffle

Abstract

Advancements in networking technologies like cloud computing have popularized applications like, Video-On Demand (VOD), video conferencing, pay-per-view, video broadcast, etc, in all such applications, confidentiality of the video data during transmission in network and during storage is extremely important. This necessitates secure video encryption algorithms suitable for multimedia application because of the large data size and real time constraint. Conventional encryption algorithms are designed for generic data, and as such, it does not support many specific video application requirements. In the paper we propose a computationally efficient and secure video encryption algorithm that makes encryption feasible for real-time applications without heavy computational overhead and reduces key management by utilizing block shuffling technique. Block Shuffling based video encryption with Faro IN OUT Shuffle and rotation, i.e., first image is rotated by an angle then key is generated based Block size using Faro IN OUT perfect shuffle which is a perfect shuffling algorithm which is isomorphic to random permutation. we will show that our proposed method provide more scrambling of image then random permutation and no need to maintain long key file.

JLVEA: Lightweight Real-Time Video Stream Encryption Algorithm for Internet of Things

“…Liu and Koenig [ 14 ], Sultana and Shubhangi [ 15 ], and Akhter et al [ 20 ] are previously proposed permutation-based video encryption algorithms (see Table 1 ). The while-compression encryption algorithm by Akhter et al performs encryption simultaneously with the moving picture experts group (MPEG) video compression [ 20 ].…”

“…The algorithm proposed by Sultana and Shubhangi [ 15 ] is a pre-compression encryption algorithm. Although pre-compression encryptions are less effective and result in large sized final cryptographic frames by including high-frequency components in the original frame, it is impossible to deduce the original video frame data based on the file structure such as the header marker and EOF marker.…”

“…For the JLVEA encryption module’s performance evaluation, we first implemented it and then performed a security analysis, encryption speed analysis, and memory efficiency analysis. The proposed algorithm along with Liu and Koenig’s [ 14 ] and Sultana and Shubhangi’s [ 15 ] algorithms were implemented in Python, and RSA encryption was performed using PyCrypto [ 24 ], the cryptographic library for Python. All experiments were performed on the BCM2837 processor [ 25 ] included in Raspberry Pi (see Table 3 ).…”

“…Moreover, if the critical file structure such as a header marker or EOF marker is lost because of packet loss while real-time streaming, the user cannot receive the complete frame data. Sultana and Shubhangi [ 15 ] proposed a permutation-based video encryption algorithm based on the faro shuffle algorithm. This algorithm is robust to a file structure inference attack since it encrypts the video stream before compression.…”
