Abstract: Stories of cyber attacks are becoming a routine in which cyber attackers show new levels of intention by sophisticated attacks on networks. Unfortunately, cybercriminals have figured out profitable business models and they take advantage of the online anonymity. A serious situation that needs to improve for networks’ defenders. Therefore, a paradigm shift is essential to the effectiveness of current techniques and practices. Since the majority of cyber incidents are human enabled, this shift requires expanding research to underexplored areas such as behavioral aspects of cybersecurity. It is more vital to focus on social and behavioral issues to improve the current situation. This paper is an effort to provide a review of relevant theories and principles, and gives insights including an interdisciplinary framework that combines behavioral cybersecurity, human factors, and modeling and simulation.

TL;DR: This paper has formulated a new algorithm for RGB image encryption and decryption using diffusion method with a combination of chaotic maps to choose keys for encrypting and decrypting RGB image.
Abstract: Image encryption and decryption are essential for securing images from various types of security attacks. In this paper, we have proposed a new algorithm for RGB image encryption and decryption using diffusion method with a combination of chaotic maps. We have formulated a new algorithm for the entire possible range to choose keys for encrypting and decrypting RGB image. Computer simulation with two standard examples and results are given to analyse the capability of the proposed approach. Several important analysis like key space, key sensitivity, NPCR, UACI, MSE and PSNR analysis are performed. Results of various analysis and computer simulation confirm that the new algorithm offers high security and is suitable for practical image encryption.
