“…A lot of research was done with different techniques such as hyper-chaos (for instance, see [4,18]); with discrete mathematical models like cellular automata (see in [19][20][21][22][23]), and Substitution, a commonly used method in [12,[24][25][26][27][28]. Further, a good survey on chaos-based cryptography can be found in [29,30].…”

So many cryptographic systems are secure and in use today, such as AES, 3DES, Blowfish, RC4, etc., however, new ideas and innovations are still highly required due to the ever-growing threats to data security. This paper presents a novel idea for symmetric image encryption utilizing binary search tree mechanism for generating the encryption/decryption key. This key consists of local and global parts with free user controlled key length, hence, it provides good flexibility for high security, which is manifested in the encrypted images. For every single byte of the encrypted image, the substitution and transposition operations involve all the image contents, fulfilling Shannon's diffusion and confusion concept. Experimental computations of the proposed encryption method have shown satisfactory visual and image energy distribution histogram. Besides, the Peak Signal to Noise Ratio (PSNR) and Normalized Mean Absolute Error (NMAE) measurement results were comparable with the widely used cryptosystems such as DES and AES. On the other hand, the proposed method has flexible key length and shorter execution time by 10% or more depending on the image contents.

“…Images and videos can be encrypted using traditional schemes such AES and DES; however, these schemes are not designed for multimedia data encryption [5][6][7]. Conventional encryption schemes have some issues such as higher computational complexity as images contain large amount of data and strong correlation among pixels.…”

With the advancement of camera and wireless technologies, surveillance camera-based occupancy has received ample attention from the research community. However, camera-based occupancy monitoring and wireless channels, especially Wi-Fi hotspot, pose serious privacy concerns and cybersecurity threats. Eavesdroppers can easily access confidential multimedia information and the privacy of individuals can be compromised. As a solution, novel encryption techniques for the multimedia data concealing have been proposed by the cryptographers. Due to the bandwidth limitations and computational complexity, traditional encryption methods are not applicable to multimedia data. In traditional encryption methods such as Advanced Encryption Standard (AES) and Data Encryption Standard (DES), once multimedia data are compressed during encryption, correct decryption is a challenging task. In order to utilize the available bandwidth in an efficient way, a novel secure video occupancy monitoring method in conjunction with encryption-compression has been developed and reported in this paper. The interesting properties of Chebyshev map, intertwining map, logistic map, and orthogonal matrix are exploited during block permutation, substitution, and diffusion processes, respectively. Real-time simulation and performance results of the proposed system show that the proposed scheme is highly sensitive to the initial seed parameters. In comparison to other traditional schemes, the proposed encryption system is secure, efficient, and robust for data encryption. Security parameters such as correlation coefficient, entropy, contrast, energy, and higher key space prove the robustness and efficiency of the proposed solution.
