Cloud computing provides many benefits in terms of low cost and accessibility of data. JAVA Ensuring the security of cloud computing is a major factor in the cloud computing environment, as users often store Cloud 2012 sensitive information with cloud storage providers but these computing providers may be untrusted. Dealing with “single cloud” providers is predicted to become less popular with customers due to risks of service availability failure and the possibility of malicious insiders in the single cloud. A movement towards “multi-clouds”, or in other words, “interclouds” or “cloud-ofclouds” has emerged recently. This paper surveys recent research related to single and multi-cloud security and addresses possible solutions. It is found that the research into the use of multicloud providers to maintain security has received less attention from the research community than has the use of single clouds. This work aims to promote the use of multi-clouds due to its ability to reduce security risks that affect the cloud computing user.2 Efficient Audit Service Outsourcing for Data Integrity in Clouds.

Active Visual Segmentation Attention is an integral part of the human visual system and has been widely studied in the visual attention literature. The human eyes fixate at important locations in the scene, and every fixation point lies inside a particular region of arbitrary shape and size, which can either be an Image entire object or a part of it. Using that fixation point as an processing identification marker on the object, we propose a method to segment the object of interest by finding the JAVA “optimal” closed contour around the fixation point in the polar space, avoiding the perennial problem of scale in the Cartesian space. The proposed segmentation process is carried out in two separate steps: First, all visual cues are 2012 combined to generate the probabilistic boundary edge map of the scene; second, in this edge map, the “optimal” closed contour around a given fixation point is found. Having two separate steps also makes it possible to establish a simple feedback between the mid-level cue (regions) and the low- level visual cues (edges). In fact, we propose a segmentation refinement process based on such a feedback process. Finally, our experiments show the promise of the proposed method as an automatic segmentation framework for a general purpose visual system.4. Persuasive Cued Click-Points. This paper presents an integrated evaluation of the Persuasive Cued Click-Points graphical password scheme, JAVA including usability and security evaluations, and implementation considerations. An important usability goal 2012 for knowledge-based authentication systems is to support users in selecting passwords of higher security, in the sense of being from an expanded effective security space. We use

Visual Cryptography. The visual cryptography (VC) is a secret sharing scheme where a secret image is encoded into transparencies, and the stacking of any out of transparencies reveals the secret image. The stacking of or fewer transparencies is unable to JAVA extract any information about the secret .We discuss the additions and deletions of users in a dynamic user group. To reduce the overhead of generating and distributing transparencies in user changes, this paper proposes a VC 2012 scheme with unlimited based on the probabilistic model. The proposed scheme allows to change dynamically in order to include new transparencies without regenerating and redistributing the original transparencies. Specifically, an extended VC scheme based on basis matrices and a probabilistic model is proposed. An equation is derived from the fundamental definitions of the VC scheme, and then the VC scheme achieving maximal contrast can be designed by using the derived equation. The maximal contrasts with to are explicitly solved in this paper.6. A Secure Intrusion detection system against DDOS attack in Wireless Mobile Ad1 Wireless Mobile ad-hoc network (MANET) is an emerging technology and have great strength to be applied in critical situations like battlefields and commercial applications such as building, traffic surveillance, MANET is infrastructure less, with no any centralized controller exist and also each node contain routing capability, Each device in a MANET is JAVA independently free to move in any direction, and will therefore change its connections to other devices frequently. So one of the major challenges wireless mobile ad-hoc networks face today is security, because no central 2012 controller exists. MANETs are a kind of wireless ad hoc networks that usually has a routable networking environment on top of a link layer ad hoc network. Ad hoc also contains wireless sensor network so the problems is facing by sensor network is also faced by MANET. While developing the sensor nodes in unattended environment increases the chances of various

There are many security attacks in MANET and DDoS (Distributed denial of service) is one of them. Our main aim is seeing the effect of DDoS in routing load, packet drop rate, end to end delay, i.e. maximizing due to attack on network. And with these parameters and many more also we build secure IDS to detect this kind of attack and block it. In this paper we discussed some attacks on MANET and DDOS also and provide the security against the DDOS attack .7. Fast Data Collection in Tree-Based Wireless Sensor Networks We investigate the following fundamental question - how fast can information be collected from a wireless sensor network organized as tree? To address this, we explore and evaluate a number of different techniques using realistic JAVA simulation models under the many-to-one communication paradigm known as converge cast. We first consider time scheduling on a single frequency channel with the aim of 2012 minimizing the number of time slots required (schedule length) to complete a converge cast. Next, we combine scheduling with transmission power control to mitigate the effects of interference, and show that while power control helps in reducing the schedule length under a single frequency, scheduling transmissions using multiple frequencies is more efficient. We give lower bounds on the schedule length when interference is completely eliminated, and propose algorithms that achieve these bounds. We also evaluate the performance of various channel assignment methods and find empirically that for moderate size networks of about 100 nodes, the use of multi-frequency scheduling can suffice to eliminate most of the interference. Then, the data collection rate no longer remains limited by interference but by the topology of the routing tree. To this end, we construct degree-constrained spanning trees and capacitated minimal spanning trees, and show significant improvement in scheduling performance over different deployment densities. Lastly, we evaluate the impact of different interference and channel models on the schedule length8. An Improved Geocast for Mobile Ad Hoc Networks Geographic addressing of packets within mobile ad hoc networks enables novel applications, including hard real-

Ph : 044-43855940 Mobile : +91-9042085008 Web : www.temasolution.com email : temasolution@gmail.com time engagement simulation in military training systems, geographic command and control functions in training and emergency communications, and commercial messaging applications as well. The most scalable implementation of geoaddressing is via a geocast protocol, where nodes JAVA selectively retransmit packets based on local decision rules. Well-designed retransmission heuristics yield scalable geographic flooding that outperforms alternative geoaddressing approaches. However, previous geocast 2012 implementations, while effective, fall into two categories. Approaches based on flooding are unscalable due to the high load they generate. Scalable approaches, on the other hand, have trouble in complex environments, lacking sufficient intelligence about the necessary directionality of packet flow. The present paper defines a novel geocast heuristic, the Center Distance with Priority (CD-P) Heuristic, which both significantly improves on reliability of existing scalable geocasts and yet also remains scalable as scenario complexity increases. This paper describes the new technique as well as an evaluation study comparing it to previous approaches .9. View-invariant action recognition based on Artificial Neural Networks In this paper, a novel view invariant action recognition method based on neural network representation and recognition is proposed. The novel representation of action videos is based on learning spatially related human body Nerual JAVA posture prototypes using Self Organizing Maps (SOM). Fuzzy Networks distances from human body posture prototypes are used to 2012 produce a time invariant action representation. Multilayer perceptrons are used for action classification. The algorithm is trained using data from a multi-camera setup. An arbitrary number of cameras can be used in order to recognize actions using a Bayesian framework. The proposed method can also be applied to videos depicting interactions between humans, without any modification. The use of information captured from different viewing angles leads to high classification performance. The proposed method is the first one that has been tested in challenging

This scheme is shown to be optimal with respect to an expected average per packet reward criterion. The proposed routing scheme jointly addresses the issues of learning and routing in an opportunistic context, where the network structure is characterized by the transmission successprobabilities. In particular, this learning framework leads toa stochastic routing scheme which optimally “explores” and“exploits” the opportunities in the network11. FireCol A Collaborative Protection Network for the Detection of Flooding DDoS Attacks Distributed denial-of-service (DDoS) attacks remain a major security problem, the mitigation of which is very hard especially when it comes to highly distributed botnet-based attacks. The early discovery of these attacks, although challenging, is necessary to protect end-users as well as the expensive network infrastructure resources. In this paper, we address the problem of DDoS attacks and present the theoretical foundation, architecture, and algorithms of FireCol. The core of FireCol is composed of intrusion prevention systems (IPSs) located at the Internet service providers (ISPs) level. The IPSs form virtual protection rings around the hosts to defend and collaborate by exchanging selected traffic information. The evaluation of FireCol using extensive simulations and a real dataset is presented, showing FireCol effectiveness and low overhead, as well as its support for incremental deployment in real network12. Load Balancing Multipath Switching System with Flow Slice.
  • 7. 28,South Usman Road,, TNagar, Chennai-17. Ph : 044-43855940 Mobile : +91-9042085008 Web : www.temasolution.com email : temasolution@gmail.com Multipath switching systems (MPS) are intensely used in state-of-the-art core routers to provide terabit or even petabit switching capacity. One of the most intractable issues in designing MPS is how to load balance traffic across its multiple paths while not disturbing the intraflow packet orders. Previous packet- based solutions suffer from delay penalties or lead to OðN2Þ hardware complexity, hence do not scale. Flow-based hashing algorithms also perform badly due to the heavy-tailed flow-size distribution. In this paper, we develop a novel scheme, namely, Flow Slice (FS) that cuts off each flow into flow slices at every intraflow interval larger than a slicing threshold and balances the load on a finer granularity. Based on the studies of tens of real Internet traces, we show that setting a slicing threshold of 1 4 ms, the FS scheme achieves comparative load-balancing performance to the optimal one. It also limits the probability of out-of- order packets to a negligible level (106) on three popular MPSes at the cost of little hardware complexity and an internal speedup up to two13. Online System for Grid Resource Monitoring. Resource allocation and job scheduling are the core functions of grid computing. These functions are based on adequate information of available resources. Timely Parallel and acquiring resource status information is of great importance Distributed in ensuring overall performance of grid computing. This Systems work aims at building a distributed system for grid resource monitoring and prediction. In this paper, we present the design and evaluation of system architecture for grid resource monitoring and prediction. We discuss the key issues for system implementation, including machine learning-based methodologies for modeling and optimization of resource prediction models. Evaluations are performed on a prototype system. Our experimental results indicate that the efficiency and accuracy of our system meet the demand of online system for grid resource monitoring and prediction.14.

An important usability goal Computing JAVA for knowledge-based authentication systems is to support users in selecting passwords of higher security, in the sense 2012 of being from an expanded effective security space. We use persuasion to influence user choice in click-based graphical passwords, encouraging users to select more random, and hence more difficult to guess, click-points15. Ensuring Distributed Accountability for Data Sharing in the Cloud Cloud computing enables highly scalable services to be easily consumed over the Internet on an as-needed basis. A major feature of the cloud services is that users data are usually processed remotely in unknown machines that users do not own or operate. While enjoying the convenience brought by this new emerging technology, users fears of losing control of their own data (particularly, financial and health data) can become a significant barrier to the wide adoption of cloud services. To address this problem, in this paper, we propose a novel highly decentralized information accountability framework to keep track of the actual usage of the usersdata in the cloud. In particular, we propose an object-centered approach that enables enclosing our logging mechanism together with users data and policies. We leverage the JAR programmable capabilities to both create a dynamic and traveling object, and to ensure that any access to users data will trigger authentication and automated logging local to the JARs. To strengthen users control, we also provide distributed auditing mechanisms. We provide extensive experimental studies that demonstrate the efficiency and effectiveness ofthe proposed approaches.16. Packet-Hiding Methods for Preventing Selective The open nature of the wireless medium leaves it vulnerable to intentional interference attacks, typically referred to as jamming. This intentional interference with wireless transmissions can be used as a launchpad for mounting Denial-of-Service attacks on wireless networks. Typically, jamming has been addressed under an external threat

However, adversaries with internal knowledge of protocol specifications and network secrets can launch low- effort jamming attacks that are difficult to detect and counter. In this work, we address the problem of selective jamming attacks in wireless networks. In these attacks, the adversary is active only for a short period of time, selectively targeting messages of high importance. We illustrate the advantages of selective jamming in terms of network performance degradation and adversary effort by presenting two case studies; a selective attack on TCP and one on routing.We show that selective jamming attacks can be launched by performing real-time packet classification at the physical layer. To mitigate these attacks, we develop three schemes that prevent real-time packet classification by combining cryptographic primitives with physical-layer attributes. We analyze the security of our methods and evaluate their computational and communication overhead.17. Risk-Aware_Mitigation for MANET Routing Attacks Mobile Ad hoc Networks (MANET) have been highly vulnerable to attacks due to the dynamic nature of its network infrastructure. Among these attacks, routing attacks have received considerable attention since it could cause the most devastating damage to MANET. Even though there exist several intrusions response techniques to mitigate such critical attacks, existing solutions typically attempt to isolate malicious nodes based on binary or naıve fuzzy response decisions. However, binary responses may result in the unexpected network partition, causing additional damages to the network infrastructure, and naıve fuzzy responses could lead to uncertainty in countering routing attacks inMANET. In this paper, we propose a risk-aware response mechanism to systematically cope with the identified routing attacks. Our risk-aware approach is based on an extended Dempster-Shafer mathematical theory of evidence introducing a notion of importance factors. In addition, our experiments demonstrate the effectiveness of our approach with the consideration of several performance metrics.

Topology Control in Mobile Ad Hoc Networks with Cooperative Communications Cooperative communication has received tremendous interest for wireless networks. Most existing works on cooperative communications are focused on link-level physical layer issues. Consequently, the impacts of Wireless cooperative communications on Communication network-level upper layer issues, such as topology control, JAVA routing and network capacity, are largely ignored. In this article, we propose a Capacity-Optimized Cooperative 2012 (COCO) topology control scheme to improve the network capacity in MANETs by jointly considering both upper layer network capacity and physical layer cooperative communications. Through simulations, we show that physical layer cooperative communications have significant impacts on the network capacity, and the proposed topology control scheme can substantially improve the network capacity in MANETs with cooperative communications.19. Privacy- and Integrity-Preserving Range Queries in Sensor Networks (1) The architecture of two-tiered sensor networks, where storage nodes serve as an intermediate tier between sensors and a sink for storing data and processing queries, has been widely adopted because of the benefits of power and storage saving for sensors as well as the efficiency of query processing. However, the importance of storage nodes also makes them attractive to attackers. In this paper, we propose SafeQ, a protocol that prevents attackers from Networking JAVA gaining information from both sensor collected data and sink issued queries. SafeQ also allows a sink to detect compromised storage nodes when they misbehave. To 2012 preserve privacy, SafeQ uses a novel technique to encode both data and queries such that a storage node can correctly process encoded queries over encoded data without knowing their values. To preserve integrity, we propose two schemes—one using Merkle hash trees and another using a new data structure called neighborhood chains—to generate integrity verification information so that a sink can use this information to verify whether the result of a query contains exactly the data items that satisfy the query. To improve performance, we propose an
