Detecting Targeted Malicious Email Through Mail Client
Get PDFSharing and storing of data in the web world is with the help of social networks. Messages are exchanged between hosts using the Simple Mail Transfer Protocol (SMTP). While the email messages are transporting between systems, SMTP communicates delivery parameters using a message envelope separate from the message (header and body) itself. A malicious email message is the one which have been deliberately crafted to cause problems on the server or at the client side. This message may contain a virus. A filtering technique is applied on messaging string contents by applying tokenization and then applying naïve bayesian classifier we classify targeted and non targeted malicious email. A network defender encounters different classes of threat actors with varying intents and capabilities. Conventional computer network attacks exploit network-based listening services such as Web servers. Traditional decision-tree classification algorithms split each node using the best split from all available features. With random forests, each node splits from a randomly selected set of features at that node. It is only focus on mail body not on hyperlinks and attachments. Proposed extension is feature extraction to file attachment metadata. Threat actors might inadvertently leave remnants of infor-mation such as file paths, time zones, or even author names. In addi¬tion, organizations can track features that characterize the types and amounts of email received by a particular email address
Enhanced Document Search and Sharing Tool in Organized P2p Frameworks
Get PDFIn internet p2p file sharing system generating more traffic. in this system file querying is important functionality which indicates the performance of p2p system .To improve file query performance cluster the common interested peers based on physical proximity .Existing methods are dedicated to only unstructured p2p systems and they don’t have strict policy for topology construction which decreases the file location efficiency. In this project proposing a proximity aware interest –clustered p2p file sharing system implemented in structured p2p file system. It forms a cluster based on node proximity as well as groups the nodes which having common interest into sub-cluster. A novel lookup function named as DHT and file replication algorithm which supports efficient file lookup and access. To reduce overhead and file searching delay the file querying may become inefficient due to the sub-interest supernode overload or failure. Thus, though the sub-interest based file querying improves querying efficiency, it is still not sufficiently scalable when there are a very large number of nodes in a sub-interest group. We then propose a distributed intra-sub-cluster file querying method in order to further improve the file querying efficiency
LD: Identifying Misbehaving Nodes in MANET
Get PDFA mobile ad-hoc network is a collection of mobile nodes connected together over a wireless medium without any fixed infrastructure. Unique characteristics of mobile ad-hoc networks such as open peer-to-peer network architecture, shared wireless medium and highly dynamic topology, pose various challenges to the security design. Mobile ad-hoc networks lack central administration or control, making them very vulnerable to attacks or disruption by faulty nodes in the absence of any security mechanisms. Also, the wireless channel in a mobile ad-hoc network is accessible to both legitimate network users and malicious attackers. So, the task of finding good solutions for these challenges plays a critical role in achieving the eventual success of mobile ad-hoc networks. However, the open medium and wide distribution of nodes make MANET vulnerable to malicious attackers. In this case, it is crucial to develop efficient intrusion-detection mechanisms to protect MANET from attacks. Secure routing protocols and mechanisms to detect routing misbehavior in the direct neighborhood exist; however, collusion of misbehaving nodes has not been adequately addressed yet.

Get PDFStarting from the quantum stochastic differential equations of Hudson and Parthasarathy Commun. Math. Phys. 93, 301 (1984) and exploiting the Wiener-Itô-Segal isomorphism between the boson Fock reservoir space �(L2(�+)�(�n��n)) and the Hilbert space L2(μ), where μ is the Wiener probability measure of a complex n-dimensional vector-valued standard Brownian motion (B(t),t�0), we derive a non-linear stochastic Schrödinger equation describing a classical diffusion of states of a quantum system, driven by the Brownian motion B. Changing this Brownian motion by an appropriate Girsanov transformation, we arrive at the Gisin-Percival state diffusion equation N. Gisin and J. Percival, J. Phys. A 167, 315 (1992). This approach also yields an explicit solution of the Gisin-Percival equation, in terms of the Hudson-Parthasarathy unitary process and a randomized Weyl displacement process. Irreversible dynamics of system density operators described by the well-known Gorini-Kossakowski-Sudarshan-Lindblad master equation is unraveled by coarse-graining over the Gisin-Percival quantum state trajectories. © 2017 Author(s)
Modified Clonal Algorithm using Deep Learning
No full textThis article uses the basic frame work of Deep Learning Mechanism (DLM) to build a potential, versatile and robust classifier which can be applied to the diverse fields like bioinformatics, networks, image processing, compression and information retrieval. Detailed studies of various types of DLM and some classes of DLM referred as MADLM (Multiple Attractor DLM), GMADLM (General Multiple Attractor DLM) and FMADLM (Fuzzy Multiple Attractor DLM) were presented with their possible applications. This article concentrates in projecting MACA as a potential classification tool for specific applications in the domain of bioinformatics and network security
Additive Cellular Automata Augmented with Deep Learning for Pattern Reorganization
No full textThis article also a new approach to classify several problems based on the properties of Additive Cellular Automata. We use a state-transition which consists of a set of disjoint trees rooted at cyclic states of unit cycle length thus forming a natural classifier. The framework proposed is strengthened with genetic algorithm to find the desired local rule of the modeling as a global state function
Cellular Automata in Indentifying Coding Sequences in DNA
No full textBiological data is exceptionally immense and unpredictable in nature. This biological data has tremendously helped scientific research immensely. This enormous data must be saved and examined for future study. Protein coding groupings are DNA arrangements that are interpreted into mRNA and in which the comparing mRNA particles are made as a polypeptide chain. Each three nucleotides, termed a codon, in a protein coding succession encodes one amino acid in the polypeptide chain. In a few cases, distinctive skeleton may either guide an offered codon to an alternate grouping or may utilize diverse codons pretty much often.DNA is encoded with information with genetic code which is a set of rules which are translated into proteins by the cells. This paper reports a fast algorithm which can predict the protein regions from DNA sequence. Even though the classifier accuracy is 78.6 but the time to identify the protein coding region is less than 5 nano seconds when tested with CONDOR data set

A vital sustainable means for community empowerment
No full textDynamic changes in the present day quality of life and quality of environment are greatly influenced by the space sciences and technology. Notwithstanding the dual use of space technology the irreversible impacts on health, resources and ecology for each abuse of finite resources are alarming. Over two decades of development reviewed by UN Systems during 1970-90s reveal that Participation is the key to Sustainability at Community Levels. Space vision of a stewardship for the present generation to sustain a healthy and safe Space ship are challenging (UNCED.1992). The next two decades after Rio'92 have also provided ample break through Space Education Out Reach activities all over the globe. Few such are Bharath Jana Vigyaan Jatha Indian People Science March ( 1987), Earth Day Network(1972) and Clean Up the World(2000) Campaigns to name a few and thousands of Community Empowerment Models which have started providing the Tunnel Effect as a societal catalyst. Thus, these living through role eco literacy models enrich and add value to the Space Education and Outreach initiatives.. Space Eco Literacy Model (Jagannatha, COSPAR 2012) provides one such simple Space Education Tool for empowering community for sustainable Development. UNESCO/UNEP/IEEP 1977 Tbilisi conference provided historical mandates for nations to embark on formal and informal environmental education. Objectives of Environmental Education for individuals and community as awareness, attitude, knowledge, skills and participation have lived through the Rio Earth Summit-1992.Pro- Active role of nations are vital to address and show case compliance to United Nations mandates. Public outreach activities need to be networked with various diversified activities aimed at space eco-literacy both at Individual and Community Levels. An EESS Ecological Environmental Studies by Students model developed in 1987 is one such Eco education Model which was cited as one of the 20 Best Eco Education Models.(Earth Day Network, 2000).In this presentation, genesis and process of development of EESS, 1987 and Space Eco-literacy, 2011 models in the backdrop of People Science Movement in India with over 35 years is captured from the Space Situational Awareness (SSA) point of view. A community eco literacy drive during 2000-2010 on the banks of Kukkarahally lake, Mysore, India for over 320 Sundays with 4500 man-hours 300 volunteers including all the authors provided the backdrop for Space Eco Literacy Campaign.. Later the effort culminated in to a Sunday Space Eco Literacy model which was developed during April-June 2011 and are discussed..

By performing a weakly non-linear stability analysis, the Nusselt number is obtained as a function of amplitude of convection which is governed by a non-autonomous Ginzburg-Landau equation derived for the stationary mode of convection. The paper succeeds in unifying the modulated Bénard-Darcy, Bénard-Rayleigh, Bénard-Brinkman and Bénard-Chandrasekhar convection problems and hence precludes the study of these individual problems in isolation. A new result that shows that asynchronous temperature modulation may be effectively used to either enhance or reduce heat transport by suitably adjusting the frequency and phase-difference of the modulated temperature is presented. © 2012 Elsevier Ltd., authorkeywords=Bénard-Darcy convection; Ginzburg-Landau amplitude equation; Nusselt number; Temperature modulation; Weakly non-linear stability analysis, keywords=Amplitude equation; Boundary temperature; Convection problem; Ginzburg-Landau equations; Modulated temperature; Phase difference; Temperature modulation; Weakly non-linear stabilities, Nonlinear equations; Nusselt number; Porous materials, Modulation, fundingdetails=University Grants Commission, references=Ahlers, G., Hohenberg, P.C., Lucke, M., Thermal convection under external modulation of the driving force, I.

This paper introduces a prototype web search results clustering engine that use the random sampling technique with medoids instead of centroids to improve clustering quality, Cluster labeling is achieved by combining intra-cluster and inter-cluster term extraction based on a variant of the information gain measure by using Modified Furthest Point First algorithm. M-FPF is compared against two other established web document clustering algorithms: Suffix Tree Clustering (STC) and Lingo, which are provided by the free open source Carrot2 Document Clustering Workbench. We measure cluster quality by considering precision , recall and relevance. Results from testing on different datasets show a considerable clustering quality. © 2013 Springer., keywords=Information retrieval; Websites, Cluster labeling; Clustering quality; Clustering system; Data sets; Document Clustering; Information gain; Intra-cluster; Medoids; Open sources; Random sampling; Suffix-trees; Term extraction; Web document clustering; Web searches, Clustering algorithms, references=Zamir, O., Etzioni, O., Web document clustering: A feasibility demonstration Proceedings of the 21st Annual International SIGIR Conference on Research and Development in Information Retrieval (1998); Hanumanthappa, M., Prakash, B.R., Mamatha, M., Improving the efficiency of document clustering and labeling using Modified FPF algorithm Proceeding of International Conference on Problem Solving and Soft Computing (2011); Geraci, F., Leoncini, M., Montangero, M., Pellegrini, M., Renda, M.E., FPF-SB: A Scalable Algorithm for Microarray Gene Expression Data Clustering (2007) LNCS, 4561, pp. 606-615. , Duffy, V.G.
