An Image Encryption using Block based Transformation and Bit Rotation Technique
Along with the rapid increasing growth of computer and network technologies, images are being transmitted more and more frequently. Security of image is a big issue. Image information is lively and visual, and has been an important means of expressing information of person. There are many encryption algorithm had been available each one having some strength and weakness. In this paper we presen...
متن کاملComments on “An Image Encryption Scheme Based on Rotation Matrix Bit-Level Permutation and Block Diffusion”
Recently, an image encryption scheme based on rotation matrix bit-level permutation and block diffusion was proposed [Y Zhang, D Xiao. Commun Nonlinear Sci Numer Simulat. 2014, 19:74-82]. In this paper, this image encryption scheme was studied in detail and its defects of low encryption speed and weak security were pointed out. This scheme with one round was crypt-analyzed successfully with the...
متن کاملImage Encryption Using Block Scrambling Technique
Due to the rapid growth of digital communication and multimedia application, security becomes an important issue in data exchange process over the wide network. In this paper, an efficient technique is presented with the help of cipher block chaining (CBC) operation ,which is used for image encryption. We test our proposed technique using MATLAB R2010a, it can achieve various image quality para...

In this paper, an efficient technique is proposed with the help of cipher block chaining (CBC) operation, which is used for image encryption. W...
متن کاملDesign and Implementation of Image Encryption Algorithm by using Block Based Symmetric Transformation Algorithm
7 Abstract: The primary goal of this paper is security management. This will provide authentication of users, and integrity, accuracy and safety of images which is traveling over internet. Moreover, an image-based data requires more effort during encryption and decryption. The Proposed Architecture for encryption and decryption of an image using suitable userdefined key is developed with the sa...
