Research ArticleOpen accessIn the author namesA VARIANT OF POLLARD'S RHO ATTACK ON ELLIPTIC CURVE CRYPTOSYSTEMSSiham Ezzouak, Mohammed Elamrani, Abdelmalek AziziElliptic Curve cryptosystems appear to be more secure and efficient when requiring small key size to implement than other public key cryptosystems. Its security is based upon the difficulty of solving Elliptic Curve Discrete Logarithm Problem (ECDLP). This study proposes a variant of generic algorithm Pollard's Rho for finding ECDLP using cycle detection with stack and a mixture of cycle … …Journal of Computer Science, Vol. 10, Issue 8 · 9 Apr 2014 · 7,272 accessesView PDFCite
Research ArticleOpen accessIn the author namesA New Approach of Almost Periodic Lumped Elements Circuits by an Iterative Method Using Auxiliary SourcesMohamed Karim Azizi, Lassaad Latrach, Nathalie Raveu et al.Nowadays, met materials with lumped or distributed elements are emerging and it is necessary to develop new techniques based on the following principles. The approach should be global and have to be formulated according to the existing classic formulations. In fact, the Wave Concept Iterative Process (WCIP) is systematically used in such application. On the other hand, the periodic medium … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 5 Oct 2013 · 6,923 accessesView PDFCite
Research ArticleOpen accessIn the author namesAnalyzing and Estimating Portfolio Performance of Bangladesh Stock MarketMd. Zobaer Hasan, Anton Abdulbasah Kamil, Adli Mustafa, Md. Azizul BatenCapital Asset Pricing Model (CAPM) is one of the most important developments in the finance literature. Simply, CAPM is a model that describes the relationship between risk and expected return. The theoretical validity of CAPM is well tested and accepted but the practical validity of CAPM is in questioned. This study is designed to analyze and estimate the portfolio performance … …American Journal of Applied Sciences, Vol. 10, Issue 2 · 6 Feb 2013 · 8,014 accessesView PDFCite
Research ArticleOpen accessIn the author namesClassification of Attacks on Embedded SystemsNoura Ouerdi, M’hammed Ziane, Abdelmalek Azizi, Mostafa AziziThe current growth of the number of Embedded Systems (ES) and their use in sensitive systems attract the attention of attackers. They are exposed to real threats and incur significant risks especially when they are involved in specific military or industrial systems. It is important to study the subject from different angles to understand, predict and learn how to protect … …Journal of Computer Science, Vol. 8, Issue 11 · 19 Sep 2012 · 6,696 accessesView PDFCite
Research ArticleOpen accessIn the author namesGC-MS Analysis and PLS-DA Validation of the Trimethyl Silyl-Derivatization TechniquesKamalrul Azlan Azizan, Syarul Nataqain Baharum, Habtom W. Ressom, Normah Mohd. NoorProblem statement: Comparison and validation analysis of the conventional and power-adjusted Microwave-Assisted (MA) techniques of TMS derivatization using Gas Chromatography-Mass Spectrometry (GC-MS) and Multivariate Analysis (MVA) of Partial Least Squares Analysis (PLS-DA). Further improvement of the conventional technique using vigorous shaking was tested and analyzed.
