Research ArticleOpen accessPhrase in the titleDSP-128:Stream Cipher Based On Discrete Log Problem And Polynomial ArithmeticKhaled M. Suwais, Azman SamsudinDSP-128 is a new multithreaded stream cipher based on the intractability of the Discrete Logarithm Problem (DLP) with key size of 128-bit. The design of DSP-128 is divided into three stages: Initialization Stage, Keystream Generation Stage, and Encryption Stage. The design goal of DSP-128 is to come up with a secure stream cipher with good performance for data encryption. The … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,396 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsA Key Dependent Encryption Algorithm Based on Multiple Bitwise-Shuffling and XOR Variable-Length PartitionsAbdelfatah Aref TamimiThis new algorithm employs shuffling procedures combined with variable-length key-dependent XOR and S-box substitutions to perform lossless image encryption. This algorithm was implemented and tested by performing different permutations of shuffling, XOR encryption and S-box substitution. Empirical analysis using different types of test images of different sizes showed that this new algorithm is effective and resistant to statistical attacks. The … …Journal of Computer Science, Vol. 12, Issue 2 · 26 Mar 2016 · 7,679 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Chaotic Block Cipher for Real-Time MultimediaN. Radha, M. VenkatesuluProblem statement: The widespread use of image, audio and video data makes media content protection increasingly necessary and important. We propose a naive approach which treats the multimedia signal to be protected as a text and use proposed encryption design to encrypt the whole data stream. Upon reception, the entire cipher text data stream would be decrypted and playback can … …Journal of Computer Science, Vol. 8, Issue 6 · 27 Apr 2012 · 7,306 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA New Type of Network Security Protocol Using Hybrid Encryption in Virtual Private NetworkingE. Ramaraj, S. KarthikeyanToday wireless communications is acting as a major role in networks. Through year-end 2006, the employee's ability to install unmanaged access points will result is more than 50% of enterprises exposing sensitive information through the wireless virtual private networks (VPN). It enables you to send the data between two computers across a shared or public network in a manner that … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,788 accessesView PDF Cite
