Research ArticleOpen accessIn the keywordsPhase Transition in Φ6 PotentialHatem WidyanScalar field theory with an asymmetric potential was studied at zero temperature and high-temperature for Φ6 potential. The equations of motion are solved numerically to obtain O(4) spherical symmetric and O(3) cylindrical symmetric bounce solutions. These solutions control the rates for tunneling from the false vacuum to the true vacuum by bubble formation. The range of validity of the thin-wall … …American Journal of Applied Sciences, Vol. 3, Issue 7 · 31 Jul 2006 · 6,878 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNearly Partial Derivations on Banach Ternary AlgebrasM. Eshaghi, M. B. Savadkouhi, M. Bidkham et al.Problem statement: In this study, we introduce the concept of a partial ternary derivation from A1 ×···× An into B, where A1, A2···, An and B are ternary algebras. Conclusion/Recommendations: We prove the generalized Hyers-Ulam stability of partial ternary derivations in Banach ternary algebras. …Journal of Computer Science, Vol. 6, Issue 4 · 31 Dec 2010 · 7,060 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Bit-Serial Multiplier Architecture for Finite Fields Over Galois FieldsHero Modares, Yasser Salem, Rosli Salleh, Majid Talebi ShahgoliProblem statement: A fundamental building block for digital communication is the Public-key cryptography systems. Public-Key Cryptography (PKC) systems can be used to provide secure communications over insecure channels without exchanging a secret key. Implementing Public-Key cryptography systems is a challenge for most application platforms when several factors have to be considered in selecting the implementation platform. Approach: The most popular … …Journal of Computer Science, Vol. 6, Issue 11 · 23 Oct 2010 · 8,431 accessesView PDFCite
Literature ReviewOpen accessIn the abstractA Review on Heuristics for Addition Chain Problem: Towards Efficient Public Key CryptosystemsAdamu Muhammad Noma, Abdullah Muhammed, Mohamad Afendee Mohamed, Zuriati Ahmad ZulkarnainField exponentiation and scalar multiplication are the pillars of and the most computationally expensive operations in the public key cryptosystems. Optimizing the operation is the key to the efficiency of the systems. Analogous to the optimization is solving addition chain problem. In this study, we survey from the onset of the addition chain problem to the state-of-the-art heuristics for optimizing … …Journal of Computer Science, Vol. 13, Issue 8 · 1 Jun 2017 · 8,163 accessesView PDFCite
Research ArticleOpen accessIn the abstractERROR DETECTION SCHEMES FOR FINITE FIELD MULTIPLIERSB. Sargunam, R. DhanasekaranFinite field multipliers are widely used in the field of cryptography for the purpose of scalar multiplication. The outputs of the finite field multipliers may consist of errors due to certain natural radiations which further leads to the failure of the cryptosystems. Here two Concurrent Error Detection (CED) schemes namely time redundancy and modular inversion based error detection schemes for … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 11 Dec 2013 · 6,913 accessesView PDFCite
Research ArticleOpen accessIn the abstractIndoor Navigation to Support the Blind Person Using True Pathway within the MapAbbas M. Ali, Md Jan NordinProblem statement: Map creation remains a very active field in the robotics and AI community, however it contains some challenge points like data association and the high degree of accuracy of localization which are seems to be difficult in some cases, more than that, most of these study focus on the robot navigation, without any consideration for the semantic of … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 6,832 accessesView PDFCite
Research ArticleOpen accessIn the abstractReconfigurable Elliptic Curve Crypto-Hardware Over the Galois Field GF(2163)Mohamed Abdelkader Bencherif, Hamid Bessalah, Abderrezak GuessoumProblem statement: In the last decade, many hardware designs of elliptic curves cryptography have been developed, aiming to accelerate the scalar multiplication process, mainly those based on the Field Programmable Gate Arrays (FPGA), the major issue concerned the ability of embedding this strategic and strong algorithm in a very few hardware. That is, finding an optimal solution to the one … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,346 accessesView PDFCite
