Conference Proceeding: Cryptanalysis of Chaos Based Secure Satellite Imagery Cryptosystem.[show abstract] [hide abstract]
ABSTRACT: Recently Usama et al. proposed a chaos-based satellite image cryptosystem, which employed multiple one-dimensional chaotic maps in novel manner to enhance the robustness, security and efficiency of sensitive satellite imagery. It is very efficient in terms of encryption time. The authors of the cryptosystem under study claimed that it has high level of security and can be applied to transmit confidential multimedia images over Internet/shared network. Unfortunately, the security analysis of the cryptosystem reveals that it has serious security flaws. Consequently, it is susceptible to a number of attacks. In this paper, the cryptanalysis of original cryptosystem is presented and it is shown that the attacker can recovers the plain-image from given cipher-image under three types of classical cryptographic attacks without knowing the secret key. The simulation results of cryptanalysis demonstrate that the cryptosystem highly lacks security and cannot be utilized for the protection of confidential/sensitive multimedia images such as the satellite imagery.Contemporary Computing - 4th International Conference, IC3 2011, Noida, India, August 8-10, 2011.
