Research ArticleOpen accessIn the abstractChallenges of Hidden Data in the Unused Area Two within Executable FilesA. W. Naji, A. A. Zaidan, B. B. ZaidanProblem statement: The executable files are one of the most important files in operating systems and in most systems designed by developers (programmers/software engineers), and then hiding information in these file is the basic goal for this study, because most users of any system cannot alter or modify the content of these files. There are many challenges of hidden data … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 7,851 accessesView PDFCite
Research ArticleOpen accessIn the abstractGroup Re-keying Protocol Based on Modular Polynomial Arithmetic Over Galois Field GF(2n)Sundaram Sudha, Azman Samsudin, Mohammad Ahmad AliaProblem statement: In this study we propose a group re-keying protocol based on modular polynomial arithmetic over Galois Field GF(2n). Common secure group communications requires encryption/decryption for group re-keying process, especially when a group member is leaving the group. Approach: This study proposes secret keys multiplication protocol based on modular polynomial arithmetic (SKMP), which eliminates the need for the encryption/decryption … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 7,165 accessesView PDFCite
Research ArticleOpen accessIn the abstractMessage Based Random Variable Length Key Encryption AlgorithmHamid Mirvaziri, Kasmiran Jumari Mahamod Ismail, Zurina Mohd HanapiProblem statement: A block ciphers provides confidentiality in cryptography but cryptanalysis of the classical block ciphers demonstrated some old weaknesses grabbing a partial key in any stage of encryption procedure leads to reconstructing the whole key. Exhaustive key search shows that key generation should be indeterminist and random for each round. Matching cipher-text attack shows that larger size of block … …Journal of Computer Science, Vol. 5, Issue 8 · 31 Aug 2009 · 6,804 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Computation Algorithm for a Cryptosystem Based on Lucas FunctionsMohamed Othman, Esam M. Abulhirat, Zulkarnain Md Ali et al.Most of public-key cryptosystems rely on one-way functions. The cryptosystems can be used to encrypt and sign messages. The LUC Cryptosystem is a cryptosystem based on Lucas Functions. The encryption process used a public key which was known publicly and the decryption used a private key which was known only by sender and receiver of the messages. The performance of … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 6,938 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Block Cipher using Feistal's Approach Involving Permutation and Mixing of the Plaintext and the Additive Inverse of Key MatrixAruna Varanasi, S. U. KumarIn this research, we have developed a block cipher for a block of size 112 bits by using an iterative method involving a permutation of the plaintext and the subkeys generated in each iteration. Here we have represented the plaintext as a matrix of f size 14×8, comprising binary bits. In the process of encryption, we have used a key … …Journal of Computer Science, Vol. 4, Issue 2 · 28 Feb 2008 · 7,109 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Backpropagation Neural Network for Computer Network SecurityKhalil ShihabIn this paper, an efficient and scalable technique for computer network security is presented. On one hand, the decryption scheme and the public key creation used in this work are based on a multi-layer neural network that is trained by backpropagation learning algorithm. On the other hand, the encryption scheme and the private key creation process are based on Boolean … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 19,535 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Large Block Cipher Using Modular Arithmetic Inverse of a Key Matrix and Mixing of the Key Matrix and the PlaintextV. U.K. Sastry, S. Udaya Kumar, A. Vinaya babuIn this paper, we have developed a block cipher by applying an iterative method. In the process of encryption, we have used a key matrix (K) in which all the elements are binary bits. In the process of decryption, we have utilized the modular arithmetic inverse (K-1). In the process of encryption, the elements of the plaintext and the elements … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,796 accessesView PDFCite
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 PDFCite
Research ArticleOpen accessIn the abstractThe Effect of RSA Exponential Key Growth on the Multi-Core Computational ResourceMohamad A. Mohamed, Ammar Y. Tuama, Mokhairi Makhtar et al.Cryptography has been widely used as a mean to secure message communication. A cryptosystem is made up of a publicly available algorithm and a secretly kept key. The algorithm is responsible for transforming the original message into something unintelligible. The result of losing the key or cracked algorithm can be catastrophic, where all secret communications will be known to adversaries. … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 25 Nov 2016 · 7,827 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Mersenne Number Transform Diffusion Power AnalysisM. F. Al-Gailani, S. BoussaktaProblem statement: Due to significant developments in the processing power and parallel processing technologies, the existing encryption algorithms are increasingly susceptible to attacks, such as side-channel attacks, for example. Designing new encryption algorithms that work efficiently on different platforms and security levels to protect the transmitted data from any possible attacks is one of the most important issues in today’s … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 12 Jan 2012 · 7,448 accessesView PDFCite
