Research ArticleOpen accessIn the keywordsRandomness Analysis of DES Ciphers Produced with Various Dynamic ArrangementsMalik Qasaimeh, Raad S. Al-QassasOver the past few years, researchers have devoted efforts to enhance the original DES encryption algorithm. These enhancements focus on improving multiple perspectives of the algorithm through enhancing its internal components to deliver a robust DES variant against different kinds of typical attacks such as linear and differential crypto analysis, in addition to the newly evolved attacks such as differential … …Journal of Computer Science, Vol. 13, Issue 12 · 15 Dec 2017 · 7,161 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAn Efficient Approach for Query Processing Over Encrypted DatabaseJaafer Al-SarairehA novel approach proposes in this research to improve the performance of the query over encrypted database. This approach based on using hash map function to generate a unique hash value for each and every sensitive data. In this a proposed approach, there are no relationship between the hashed value and encrypted value. This method can reduce the cost of … …Journal of Computer Science, Vol. 13, Issue 10 · 18 Oct 2017 · 7,173 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPERFORMANCE ANALYSIS OF IMAGE SECURITY BASED ON ENCRYPTED HYBRID COMPRESSIOND. Ramkumar, I. Jacob RaglendIn this research, we propose an image security scheme using hybrid compression techniques. In this scheme, the data is being provided two-fold security by both encryption stage and hiding stage. The data/message which has to be secured undergoes encryption technique at the initial stage. In this stage, the permutation algorithm is employed which requires a pair of numbers as a … …American Journal of Applied Sciences, Vol. 11, Issue 7 · 26 Apr 2014 · 6,712 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Block Cipher Algorithm for Multimedia Content Protection with Random Substitution using Binary Tree TraversalP. Vidhya Saraswathi, M. VenkatesuluMany people consume multimedia content (images, music, movie) on portable devices like DVD player, MP3 player, Portable Multimedia Player and also through Internet. Problem statement: The conventional algorithms such as DES and AES cannot be used directly in multimedia data, since multimedia data are repeatedly have high redundancy, large-volumes and require real-time operations, such as displaying, cutting, copying, bit-rate conversion … …Journal of Computer Science, Vol. 8, Issue 9 · 15 Aug 2012 · 7,694 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA 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 PDFCite
Research ArticleOpen accessIn the keywordsNew Approaches to Ancient Crypto-Steganography MethodsA. Joseph Raphael, V. SundaramProblem statement: The requirement and ability to hide information from others has existed in the world for centuries. Cryptography and steganography are the most commonly used techniques for information sharing. The science of securing a data by encryption is cryptography whereas the method of hiding secret messages in other media is Steganography, so that the secret’s very existence is concealed. … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 4 Nov 2011 · 8,110 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNovel Mechanism Control Algorithm for Wired NetworkV. B. Kirubanand, S. PalaniammalProblem statement: A critical issue in wireless network where the data can hack by the person and we add a novel encryption mechanism to protect the data transfer from client to server and vice versa. Approach: We present a queuing model of a client and server that uses for bulk arrival service. The arrival of data requests is assumed to … …Journal of Computer Science, Vol. 7, Issue 9 · 27 Jul 2011 · 6,651 accessesView PDFCite

Al MijalliProblem statement: The S-Box transformation is a computationally intensive and important operation of the Advanced Encryption Standard (AES). Approach: This study presents the comparative study between reduced Residue of Prime Numbers and Galois Filed GF (28) based SBoxes using Virtex-5 and Virtex-6 FPGA devices. The implementation of S-Boxes is done using Very High speed integrated circuit Hardware Description Language (VHDL). … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 18 Jul 2011 · 6,975 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAuthenticated Broadcast in Heterogeneous Wireless Sensor Networks using Chinese Remainder Theorem AlgorithmKalyani Palanisamy, ChellappanProblem statement: The security in Wireless Sensor Networks (WSN) is a critical issue due to the inherent limitations of computational capacity, storage capacity and power usage. Key management only makes sure the communicating nodes possess the necessary keys, at the same time protecting the confidentiality, integrity and authenticity of the communicated data. Approach: Proposed a RSA-CRT methodology for authenticated broadcast … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 6,413 accessesView PDFCite
