Fisher-Yates Chaotic Shuffling Based Image Encryption
In Present era, information security is of utmost concern and encryption is one of the alternatives to ensure security. Chaos based cryptography has brought a secure and efficient way to meet the challenges of secure multimedia transmission over the networks. In this paper, we have proposed a secure Grayscale image encryption methodology in wavelet domain. The proposed algorithm performs shuffl...
متن کاملChaos Image Encryption using Pixel shuffling
The advent of wireless communications, both inside and outside the home-office environment has led to an increased demand for effective encryption systems. The beauty of encryption technology comes out in more pronounced way when there is no absolute relation between cipher and original data and it is possible to rebuild the original image in much easier way. As chaotic systems are known to be ...
متن کاملImproving Chaos Image Encryption Speed
Chaotic systems are extremely sensitive to control parameters and initial conditions. This feature is effective in the field of cryptography. In this paper we propose image encryption scheme which is based on the chaotic maps of Peter de Jong’s attractor. The image is transferred into the wavelet domain and then appropriate modifications of the wavelet coefficients are done. The main purpose of...
متن کاملImage Encryption Based on Pixel Shuffling and Random Key Stream
Secured data storage and transmission has become an important issue in the digital world due to the increased use of Internet for communication purposes. Information security is becoming more important as the amount of sensitive data being exchanged on the Internet increases. The services like confidentiality and data integrity are required to protect data against unauthorized usage and modific...
متن کاملDigital Image Encryption Method Using Interleaving and Random Shuffling
Distribution of digital multimedia contents which are used for broadband communication makes it possible for users to have joint ownership of information. It means that illegal copy and forgery of digital contents is possible to individuals. Therefore, it is necessary to protect right of contents authorship using digital watermarking or digital encryption. When watermarking and encryption are c...
