Based on Spatiotemporal Chaos . Here, we process three color components simultaneously instead of individually, and consider the correlation between them. In the CS phase, the plain image is compressed and encrypted by chaos- based Bernoulli measurement matrix, which is generated under the control of the introduced Chebyshev map. To decrypt, APE processes the ciphertext blocks in reverse order, and uses inverse permu-tation calls. The major advantage of the proposed strategy is the dynamic aspect of keys used by chaotic map to generate strong S-boxes.

Downloaded on September 07,2020 at 03:15:29 UTC from IEEE Xplore. This paper proposes a block-permutation-based encryption (BPBE) scheme for the encryption-then-compression (ETC) system that enhances the color scrambling. A new chaotic image encryption scheme based on permutation and substitution in the Fourier domain is presented. The confusion and diffusion effect is solely contributed by the permutation and the diffusion stage, respectively. AU - Yoon, Ji Won. In the achievability scheme for the reversed system proposed in [4], the source is first encrypted by a modulo-sum cipher with the help of a secret key, and then compressed by a Wyner-Ziv source encoder [5]. Authors: Akram Belazi. Keywords.Padding-based encryption,OAEP,black-box,ideal trapdoor permutations. e proposed scheme can simultaneously encrypt and compress the medical image using compressive sensing (CS) and pixel swapping based permutation approach. In recent years, a variety of effective chaos-based image encryption schemes have been proposed. 2 Is there a way to double the size of ciphertexts of a public-key scheme which is IND-CCA2 We give insight into their designs, also covering resistance against side-channel attacks. encryption-RDH scheme in this paper. public networks. Relative cryptanalysis achievements usually focus on a specific encryption scheme. The rest of the paper is organized as follows. PY - 2010/12 . Firstly, a simple and efficient S-box method is introduced in order to use this S-box designed scheme in secure color image encryption technique. DWT, permutation (confusion), and diffusion stages are The main idea of the proposed scheme, called PPE, is that only GEVs are permuted instead of the whole packets at the source. A novel chaos-based image encryption scheme has been proposed recently. Trail Bound Techniques in Primitives with Weak Alignment. A Chaotic Image Encryption Scheme with Complex Diffusion Matrix for Plain Image Sensitivity Janani Thiyagarajan1, Brindha Murugan1, ... cipher, there are two phases for encryption: permutation and diffusion. Chaotic Encryption Scheme Based on A Fast Permutation and Diffusion Structure Jean De Dieu. They also presented a method, called Optimal Asymmetric Encryption Padding (OAEP), that converts any trap-door permutation f into an IND-CCA1 public-key encryption scheme in the random oracle model [6]. Encryption Process. It is found out through experiments that the proposed permutation in the integer DWT domain can achieve the same results as the proposed sample permutation scheme in the spatial domain. Next, the paper presents the permutation matrix encryption based ultralightweight secure RFID scheme in IoV in Section 3. encryption schemes that have passed these tests were cracked [22]–[26]. e proposed image encryption plot dependent on chaos structure is delineated in Figure 11(a). After that, the keystream is employed to mask the permutated image to get the cipher-image. Encryption Schemes ∗ Eiichiro Fujisaki and Tatsuaki Okamoto ... from any trap-door permutation to an IND-CCA2 public-key encryption scheme in the random oracle model [5]. 3 where we also discuss its properties and provide a security claim. Abstract: Permutation is a commonly used primitive in multimedia (image/video) encryption schemes, and many permutation-only algorithms have been proposed in recent years for the protection of multimedia data. In this paper, an image encryption algorithm based on 3-D DNA level permutation and substitution scheme is proposed. Gang Xu, Xuna Miao, Yafeng Zheng . 1 Introduction 1.1 Padding schemes for encryption Optimal Asymmetric Encryption Padding (OAEP) is one of the most known and widely deployed asymmetric encryption schemes. Partial Permutation Based Encryption (PPE) Scheme. In this scheme, redundancies of the Fridrich’s structure were reduced significantly via a new circular inter-intra-pixels bit-level permutation strategy. Are there deterministic private-key encryption schemes that are CPA-secure? A BPBE image can be obtained through four processes, positional scrambling, block rotation/flip, negative-positive transformation, and color component shuffling, after dividing the original image into multiple blocks. At the receiver side, joint reconstruction-decryption is conducted by viewing the secret key as side information and performing the Wyner-Ziv decoding procedure. In Section II, we first briefly introduce the 2D chaotic cat map and discuss its chaotic natures. N2 - Many research efforts for image encryption schemes have elaborated for designing nonlinear functions since security of these schemes closely depends on inherent characteristics of nonlinear functions. A novel image encryption scheme based on substitution-permutation network and chaos. The permutation is achieved by Baker map and the substitution by a key-related-to-plain-image algorithm based on the modified Logistic map. APE therefore requires a permutation that is both efficient for forward and inverse calls. In permutation-only image ciphers, the entries of the image matrix are scrambled using a permutation mapping matrix which is built by a pseudo-random number generator. The plain image is firstly divided into 8 bit panels and then arranged into two groups. It was designed by Bel-lare and Rogaway [3] as a scheme based on a trapdoor permutation (TDP). Silvia Mella. − After the expansion permutation, DES does XOR operation on the expanded right section and the round key. Y1 - 2010/12. Fractional Fourier Transform (FRFT) is used before the encryption scheme to get a large degree of randomization. This paper cryptanalyzes a family of image encryption schemes that adopt pixel-level permutation and modular addition-based substitution. The typical structure of these schemes has the permutation and the diffusion stages performed alternatively.

April 2016 ; Signal Processing 128; DOI: 10.1016/j.sigpro.2016.03.021. Three procedures generally exist in such image encryption schemes: the key schedule module for producing encryption elements, permutation for image scrambling and substitution for pixel modification. However, we proved that the original encryption scheme is vulnerable to the known/chosen-plaintext attacks. This makes sufficient confusion for an adversary to locate GEVs in order to get meaningful information. This talk is about two permutation-based authenticated encryption schemes. image encryptions are proposed such as DNA sequence An Encryption Scheme for Images Based on Chaotic Key Generation and Block Level Permutation P. Mithun1, R. Sandhiya2, J. Indumathi3 1,2M.Tech. January 2011; Communications in Computer and Information Science 131:413-427; … Abstract: To improve the abilities of image encryption systems to resist plaintext attacks and differential attacks, a novel plaintext-related image encryption scheme based on Josephus traversing and pixel permutation is proposed. The first one is Ascon, a finalist of CAESAR, and the second one is Isap, a scheme focusing on protection against DPA. encryption scheme is robust and secure and can be used for secure image and video communication applications. In this paper, two efficient cryptosystem schemes in the form of permutation–substitution based on chaotic systems are proposed. This paper analyses the aws of … Permutation and ff are two basic principles in designing an image encryption algorithm. Then we devote t o designing the image encryption scheme. The permutation is performed on each group based on the feature of the other group. 4. 2Department of Communications, Technical University of Cluj-Napoca, Romania . By keeping the permutation operation of the neural synaptic matrix as the secret key, we introduce a new probabilistic encryption scheme for a symmetric-key cryptosystem. after encryption. Finally, some conclusions of the proposed scheme and the discussion of the … technique. However, this has still been the case mostly in the stream-cipher mode. 1. Almost all image encryption methods are based on a scheme that separates permutation and ff namely, asynchronous permutation and ff scheme (APDS). We combine permutation and diffusion processes into a whole, namely, simultaneous permutation and diffusion operation (SPDO). 3Department of Electrical Engineering, Energetics and Automatics, University … The scheme is based on a permutation called Friet-P and its embedding Friet-PC that we present in Sect. As we are permuting only GEVs, this significantly reduces the complexity and making the scheme more efficient. Authorized licensed use limited to: Universidade de Macau. Permutation logic is graphically depicted in the following illustration − The graphically depicted permutation logic is generally described as table in DES specification illustrated as shown − XOR (Whitener). As mentioned above, the Kec- cak team has proved that one can build authenticated-encryption stream-cipher modes using the very same public Keccak permutation [6] on which SHA-3 (as a random oracle) is built. In the proposed encryption scheme, the chaotic map is used to design the plaintext dependent bit-level permutation. T1 - An image encryption scheme with a pseudorandom permutation based on chaotic maps.
