Abstract-Chaotic system based message encryption system for wired and wireless networks broadly used in computer engineering, communication and network security, such as robotic systems, encryption, synchronization and genetic network. The main motive for developing the chaos based cryptosystem is to attain encryption with several compensation over the conventional encryption algorithms such as high security, speed, complexity, cost and quality assurance. These challenges encourage the researchers to develop novel chaos based data encryption techniques with digital logics dealing with encryption of messages for fast and secure communication networks. This effort provides a modified version of traditional data encryption algorithms to provide good quality and performance in a secure communication network environment. A cryptology technique is widely used in network security during communication. An avalanche effect is the attractive property of cryptography in which two different keys produce different cipher text for the same data information and also some Important properties related to chaotic systems are sensitivity to initial condition and nonlinearity, which makes two similar or slightly different keys to generate completely different cipher text to produce confusion. It has been proposed a novel fast & secure encryption Technique which uses the chaotic map function to generate the different multiple keys and shows that negligible difference in parameters of chaotic function generate completely different keys as well as cipher text. Cryptanalysis of the proposed algorithm shows the strength and security of algorithm and keys.

“…However, Kumar et al [34] have demonstrated the vulnerability of (DRPAE) scheme in front of a point spread function attack and He et al [33] have proved that DRPAE is also vulnerable to a Hybrid two-step attack, which utilizes a chosen-plaintext attack followed by a known-plaintext attack. Recently, Elshamy et al [45] proposed an optical image encryption method based on chaotic Baker map and DRPE, which consists of two layers. The first layer is a preprocessing chaotic baker map which performs the randomization of the image pixels and the second layer is the conventional DRPE.…”

Abstract. We propose an optical security technique for image encryption using triple random phase encoding (TRPE). In the encryption process, the original image is first double random phase encrypted. The obtained function is then multiplied by a third random phase key in the output plane, to enhance the security level of the encryption process. This method reduces the vulnerability to certain attacks observed when using the conventional double random phase encoding (DRPE). To provide the security enhancement of the proposed TRPE method, three attack cases are discussed: Chosen-plaintext attacks (CPA), Known-plaintext attacks (KPA) and chosen-ciphertext attacks (CCA). Numerical results are presented to demonstrate feasibility and effectiveness of the proposed method. Compared with conventional DRPE, the proposed encryption method can provide an effective alternative and has enhanced security features against the above-mentioned attacks.

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. General TermsSecurity, Image Encryption.
