Research ArticleOpen accessEvery word in the titleTopological Decoupled Group Key Management for Cellular NetworksJorge Estudillo Ramirez, Saul Eduardo Pomares Hernandez, Gustavo Rodriguez Gomez, Jose Roberto Perez CruzProblem statement: The continuous increasing capacity of the cellular networks motivates the development of multiparty applications, such as interactive mobile TV and mobile social networks. For these environments, security group services are required. A practical way to provide security services is by using cryptographic methods. However, the key management needed for these methods, which considers a dynamic group membership, introduces … …Journal of Computer Science, Vol. 7, Issue 3 · 9 Mar 2011 · 6,866 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA New Scalable and Reliable Cost Effective Key Agreement Protocol for Secure Group CommunicationS. Jabeen Begum, Dr. T. PurusothamanProblem statement: In a heterogeneous environment, for a secure multicast communication, the group members have to share a secret key which is used to encrypt/decrypt the secret messages among the members. The Secure Group Communication of large scale multicast group in a dynamic environment is more complex than securing one-to-one communication due to the inherent scalability issue of group key … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 6,960 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Developmental Model of Cultural Tourism-Homestay of the Lao Vieng and Lao Song Ethnic Groups in the Central Region of ThailandSupon Chaiyatorn, Prarop Kaoses, Phairat ThitphatProblem statement: Lao Wieng and Lao Songe Ethnic Groups were herded from Lanchang Region to Siam Region. In recent time, they settled down in Central Thailand. The objectives of this research were to study: (1) historical background of Lao Wieng and Lao Songe Ethnic Groups, (2) their lifestyle facilitating tourism and (3) development of cultural tourism model as Home Stay … …Journal of Social Sciences, Vol. 6, Issue 1 · 31 Mar 2010 · 9,657 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSilk-Cloth Weaving Development of the Mon-Khmer Ethnic Group in Lower-IsanWira Phansuwan, Suoneth Photisan, Anongrit KangrangProblem statement: Silk cloth weaving culture of the Mon-Khmer ethnic group in Lower-Isan has a specific identity which should be handed down to future generation. The purposes of this research were to examine: (1) the body knowledge concerning silk clothes of the Mon-Khmer ethnic group in Lower-Isan region, (2) the process of production or silk-cloth weaving of the Mon-Khmer ethnic … …Journal of Social Sciences, Vol. 6, Issue 1 · 31 Mar 2010 · 8,765 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Framework for Group Key Management Protocol Assessment Independent of View SynchronyDavid Manz, Paul Oman, Jim Alves-FossProblem statement: As group key management extended into the area of large dynamic networks, complex issues emerged involving the many operations that run over several network topologies. The issues that occurred due to multiple topologies were also compounded by differing views of the network, taken at different time slices or positions within the network. This was especially complex when figuring … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 6,942 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGroup 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 accessEvery word in the titleComparison of Bleeding Time and Clotting Time in Different Blood GroupsB. Mahapatra, N. MishraProblem statement: Researchers have demonstrated that epistaxis is more often encountered in patients having blood group O probably due to lower expression of von Willebrand factor. We had taken up this study to find out if there is any definite relationship between the blood groups with the bleeding time and clotting time in our population. Approach: This retrospective study was … …American Journal of Infectious Diseases, Vol. 5, Issue 2 · 30 Jun 2009 · 10,976 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComplex Specializations of Krammer's Representation of the Braid Group, B3Mohammad N. Abdulrahim, Madline Al-TahanProblem statement: Classifying irreducible complex representations of an abstract group has been always a problem of interest in the field of group representations. In our study, we considered a linear representation of the braid group on three strings, namely, Krammer's representation. The objective of our work was to study the irreducibility of a specialization of Krammer's representation. Approach: We specialized … …Journal of Mathematics and Statistics, Vol. 4, Issue 4 · 31 Dec 2008 · 7,492 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCharacterization of Chain as a Regular Semi GroupR. Kehinde, S.O. MakanjuolaProblem Statement: There are some special classes of semi group namely: regular and eventually regular, abundant, orthodox, quasi-adequate. The objective of this study were to: (i) Define a new class of semi group on a Poset and give related examples (ii) Study and establish conditions that characterized Chain as a regular semi group. Approach: Tests of some of characteristics of … …Journal of Mathematics and Statistics, Vol. 4, Issue 4 · 31 Dec 2008 · 6,787 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Aggregation Approach for Group Multicriteria AssignmentGeorge Rigopoulos, John Psarras, Dimitrios Th. AskounisWe presented an aggregation approach for group multicriteria assignment decisions, where group members express their preferences on problem parameters in numeric format. Individual preferences are aggregated by WOWA operator following the majority concept and a group parameter set is derived that is used as input for the classification algorithm. In addition, we present a numeric example of the approach, demonstrating … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,548 accessesView PDFCite
