Mohammed A. AlZain, Osama S. Faragallah . Efficient Chaotic Tent Map-based Image Cryptosystem. International Journal of Computer Applications. 167, 7 ( Jun 2017), 12-17. DOI=10.5120/ijca2017914237
This paper presents an efficient chaotic image encryption cipher that is designed with the aim of improving the security and enhancing the encryption efficiency. In this paper, a chaotic tent map (CTM) is utilized to build a new digital chaotic image cryptosystem. The characteristics of CTM are very suitable for the design of encryption schemes. The security estimation of the proposed CTM-based image cryptosystem against brute-force, statistical, and differential attacks is investigated from strict cryptographic viewpoint. Experimental tests are performed with detailed analysis confirming the high security of the proposed CTM-based image cryptosystem.
