Abstract
Wireless multimedia communications have progressed significantly in recent years. As a result, there is an increasing demand for more secure media transmission to protect multimedia information. Image encryption systems have been presented throughout the years, but those based on chaotic maps are the most secure and trustworthy due to the inherent properties in such types of multimedia contents involving the pixels strong correlation and data handling capacities. In this research, we have performed differential cryptanalysis of a recently suggested cryptosystem based on a three dimensional (3D) logistic map and 3D Cat map. The originally proposed approach was based on diffusion and confusion strategy. The vulnerabilities in the understudy cryptosystem lead to the successful proposed cryptanalysis attack. The original ciphers are recovered by means of a chosen-plaintext attack. The recovered data is also subjected to some statistical analysis to check the quality.
