Research ArticleOpen accessPhrase in the titleKey Based Random Permutation (KBRP)Shakir M. Hussain, Naim M. AjlouniThis study introduces a method for generating a particular permutation P of a given size N out of N! permutations from a given key. This method computes a unique permutation for a specific size since it takes the same key; therefore, the same permutation can be computed each time the same key and size are applied. The name of random … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 7,366 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Flexible, Real-Time Algorithm for Simulating Correlated Random Fields and Its PropertiesMichael A. Kouritzin, Fraser Newton, Biao WuContemporary real-time problems like CAPTCHA generation and optical character recognition can be solved effectively using correlated random fields. These random fields should be produced on a graph in order that problems of any dimension and shape can be handled. However, traditional solutions are often too slow, inaccurate or both. Herein, the Quick Simulation Random Field algorithm to produce correlated random … …Journal of Mathematics and Statistics, Vol. 13, Issue 3 · 29 Sep 2017 · 7,069 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Password-Based Key Derivation Algorithm Using the KBRP MethodShakir M. Hussain, Hussein Al-BahadiliThis study presents a new efficient password-based strong key derivation algorithm using the key based random permutation the KBRP method. The algorithm consists of five steps, the first three steps are similar to those formed the KBRP method. The last two steps are added to derive a key and to ensure that the derived key has all the characteristics of … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 6,886 accessesView PDFCite
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 PDFCite
Research ArticleOpen accessIn the abstractA Non-Exchanged Password Scheme for Password-Based Authentication in Client-Server SystemsShakir M. Hussain, Hussein Al-BahadiliThe password-based authentication is widely used in client-server systems. This research presents a non-exchanged password scheme for password-based authentication. This scheme constructs a Digital Signature (DS) that is derived from the user password. The digital signature is then exchanged instead of the password itself for the purpose of authentication. Therefore, we refer to it as a Password-Based Digital Signature (PBDS) … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,002 accessesView PDFCite
