Research ArticleOpen accessIn the abstractAltered Reproduction in Clarias gariepinus Exposed to Industrial EffluentsAdeogun Aina Olubukola, Chukwuka Azubuike VictorProblem statement: Reproductive success is a key factor in determining species survival and the unregulated discharge of industrial effluents into rivers and streams in a developing country like Nigeria, can impair reproductive ability in non-target organisms like fish. Fish, generally accumulate contaminants from their environment in their tissues and these can be transmitted through the yolk lipids to the eggs. … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 21 Feb 2012 · 7,706 accessesView PDFCite
Research ArticleOpen accessIn the abstractMobile Node Speed Detection Mechanism in Hierarchical Mobile Internet Protocol (IPv6)Zulkeflee Kusin, Mohamad Shanudin ZakariaProblem statement: IETF has introduced Hierarchical Mobile IPv6 (HMIPv6) to support mobility problem in the next generation Internet Protocol (IPv6). The key concept behind this protocol is the usage of Mobility Anchor Point (MAP) located at any level router of network to support hierarchical mobility management and seamless handover. The distance MAP selection in HMIPv6 causes MAP overloaded as the … …Journal of Computer Science, Vol. 7, Issue 9 · 27 Jul 2011 · 6,614 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Secure Simple Authenticated Key Exchange Algorithm based Authentication for Social NetworkP. Venkateswari, T. PurusothamanProblem statement: This study describes about a robust and secured authentication procedure that can be adapted in a private forum within a Social Network Site (SNS) to update its user’s profile. Approach: The robustness is achieved through combining proven security measures combined with usability aspects. The study demonstrates acceptance of such robustness particularly in a SNS to update user’s profile. … …Journal of Computer Science, Vol. 7, Issue 8 · 14 Jul 2011 · 6,594 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Certificate-Free Key Distribution Protocol for Secure Group Communication in Grid EnvironmentMandadi Venkatesulu, Kamatchi KartheebanProblem statement: In grid environment, group communication is an important mechanism to realize large-scale information resource sharing. However providing security for group communication in grid environment is very difficult because the group is dynamic in nature. Scalable group re-keying is one of the important issues in secure group communication. These group keys should be updated whenever a member joins/leaves the … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 7,125 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Enhancement Technique of the Hill Cipher for Effective Cryptographic PurposesA. F.A. Abidin, O. Y. Chuan, M. R.K. AriffinProblem statement: The Hill cipher is the first polygraph cipher which has a few advantages in data encryption. However, it is vulnerable to known plaintext attack. Besides, an invertible key matrix is needed for decryption. It may become problematic since an invertible key matrix does not always exist. Approach: In this study, a robust Hill algorithm (Hill++) has been proposed. … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 8,545 accessesView PDFCite
Research ArticleOpen accessIn the abstractSuitable Assimilation Model of Culture, Beliefs and Rites Concerning Deities of Buddhism and Hindu-Brahmanism for Peace of Thai Society in Bangkok and CircumferencesPhra Maha Kriangkrai Kaewchaiya, Suoneth Photisan, Makhawin PurisuttamoProblem statement: At present, Thai society widely assimilates culture, beliefs and rites concerning deities of Buddhism and Hindu-Brahmanism by worshipping the deity images at the temples or the abodes of gods in Bangkok and circumferences. A typical worship is to pray the deity for help. As a matter of fact, people should help themselves first and use a prayer as … …Journal of Social Sciences, Vol. 7, Issue 2 · 8 Feb 2011 · 7,834 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Odor Key Technique for Security Applications Using Electronic Nose SystemMahmoud Z. IskandaraniProblem statement: A novel approach to security applications that makes use of odors as password generators is developed and tested. The developed system detects and converts odor signals that are randomly selected to binary signals and then intelligently compares them with previously stored values. Approach: The interface device in question then either opens its interface if comparison is successful or … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 7,186 accessesView PDFCite
Research ArticleOpen accessIn the abstractProtocol of Secure Key Distribution Using Hash Functions and Quantum Authenticated Channels (KDP-6DP)Mohammed Munther A. Majeed, Khalid A.S. Al-Khateeb, Mohamed R. Wahiddin, Magdy M. SaebProblem statement: In previous researches, we investigated the security of communication channels, which utilizes authentication, key distribution between two parties, error corrections and cost establishment. In the present work, we studied new concepts of Quantum Authentication (QA) and sharing key according to previous points. Approach: This study presented a new protocol concept that allows the session and key generation on-site … …Journal of Computer Science, Vol. 6, Issue 10 · 24 Aug 2010 · 8,271 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuantum Key Distribution Using Decoy State ProtocolSellami Ali, Shuhairi Saharudin, M. R.B. WahiddinProblem statement: Quantum key distribution provides unconditional security guaranteed by the fundamental laws of quantum physics. Unfortunately, for real-life experimental set-ups, which mainly based on faint laser pulses, the occasional production of multi-photons and channel loss make it possible for sophisticated eavesdroppers to launch various subtle eavesdropping attacks including the Photon Number Splitting (PNS) attack. The decoy state protocols recently … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 8,434 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
