Location aware computing which is evolved from pervasive computing performs services which are dependent on the location of the user or his communication device. The advancements in this area have led to major revolutions in various application areas, especially mass advertisements. It has long been evident that privacy of personal information, in this case location of the user, is rather a touchy subject with most people. This paper explores the Location Privacy issue in location aware computing. Vertical fragmentation of the stored location information of users has been proposed as an effective solution for this issue.  ...

Ahmad reza Montazerolghaem1 , Mohammad Hossein Yaghmaee2 1,2Department of Computer Engineering, Ferdowsi University of mashhad, Mashhad, Iran ABSTRACT  Having facilities such as being in text form, end-to-end connection establishment, and being independence from the type of transmitted data, SIP protocol is a good choice for signaling protocol in order to set up a connection between two users of an IP network. Although utilization of SIP protocol in a wide range of applications has made various vulnerabilities in this protocol, amongst which overload could make serious problems in SIP servers. A SIP is overloaded when it does not have sufficient resources (majorly CPU processing power and memory) to process all messages. In this paper the window-based overload control mechanism which does not require explicit feedback is developed and implemented on Asterisk open source proxy and evaluated. The results of implementation show that this method could practically maintain...

Hyun Woo Lee1 , Su Man Nam2 and Tae Ho Cho3 123College of Information and Communication Engineering, Sungkyunkwan University, Suwon 440-746, Republic of Korea  ABSTRACT  A wireless sensor network is composed of a base station (BS) and numerous sensor nodes. The sensor nodes lack security because they operate in an open environment, such as the military. In particular, a false report injection attack captures and compromises sensor nodes. The attack then causes the compromised nodes to generate forward false reports. Owing to the false report injection attack, not only does the sensor network have a false alarm, but its limited energy is also drained. In order to defend the false report injection attack, over the past few years, several studies have been made looking for a solution to the attack. Ye et al. studied statistical en-route filtering (SEF). SEF is a method of stochastically verifying event reports in the en-route filtering phase. SEF can filter many fal...

Su Man Nam and Tae Ho Cho College of Information and Communication Engineering, Sungkyunkwan University, Suwon, 440-746, Republic of Korea  ABSTRACT  Wireless sensor networks are easily compromised by an adversary, such as fabricated with false votes attacks and false votes on real reports attacks. These attacks generate false data to drain the energy resource of sensors and interrupt the inflow of a real report. PVFS was proposed to detect them by verifying votes in the real report. When a real event occurs, a cluster head collects all of the votes from its neighboring nodes and selects the votes up to a defined number of votes. In this paper, our proposed method decides the number of votes based on a fuzzy rule-based system to improve energy savings as compared to PVFS. We evaluated the effectiveness of the proposal as two attacks occur simultaneously in the sensor network. The experimental results show that our method saves energy resources and maintains the s...

Arindam Sarkar1 and J. K. Mandal2 Department of Computer Science & Engineering, University of Kalyani, W.B, India  ABSTRACT  In this paper a novel intelligent soft computing based cryptographic technique based on synchronization of two chaotic systems (CSCT) between sender and receiver has been proposed to generate session key using Pecora and Caroll (PC) method. Chaotic system has some unique features like sensitive to initial conditions, topologically mixing; and dense periodic orbits. By nature, the Lorenz system is very sensitive to initial conditions meaning that the error between attacker and receiver is going to grow exponentially if there is a very slight difference between their initial conditions. All these features make chaotic system as good alternatives for session key generation. In the proposed CSCT few parameters ( σ, b , r , x1 ,y2 and z2 ) are being exchanged between sender and receiver. Some of the parameter which takes major roles to form...

Rashmi1 , Ameeta Seehra2 Department of Electronics and Communication Engineering, Guru Nanak Dev Engineering College, Ludhiana, Punjab, India  ABSTRACT  A black-hole attack in the Mobile Ad-hoc NETwork (MANET) is an attack occurs due to malicious nodes, which attracts the data packets by falsely advertising a fresh route to the destination. In this paper, we present a clustering approach in Ad-hoc On-demand Distance Vector (AODV) routing protocol for the detection and prevention of black-hole attack in MANETs. In this approach every member of the cluster will ping once to the cluster head, to detect the peculiar difference between the number of data packets received and forwarded by the node. If anomalousness is perceived, all the nodes will obscure the malicious nodes from the network.  KEYWORDS  Mobile Ad-hoc Networks, Black-hole attack, AODV, Routing Protocols, Security, Clustering, Cluster-head.  More Details :  http://airccse...

Jae Kwan Lee1 and Tae Ho Cho2 1, 2 College of Information and Communication Engineering, Sungkyunkwan University, Suwon 440-746, Republic of Korea  ABSTRACT  Wireless sensor networks (WSNs) are regularly deployed in harsh and unattended environments, and sensor nodes are easily exposed to attacks due to the random arrangement of the sensor field. An attacker can inject fabricated reports from a compromised node with false votes and false vote-based reports. The false report attacks can waste the energy of the intermediate nodes, shortening the network lifetime. Furthermore, false votes cause the filtering out of legitimate reports. A probabilistic voting-based filtering scheme (PVFS) was proposed as a countermeasure against this type of attacks by Li and Wu. PVFS uses a vote threshold, a security threshold, and a verification node. The scheme does not make additional use energy or communications resources because the verification node and threshold values are fixed...

Su Man Nam1 and Tae Ho Cho2 1,2College of Information Communication Engineering, Sungkyunkwan University, Suwon, 400-746, Republic of Korea  ABSTRACT   Wireless sensor networks provide ubiquitous computing systems in various open environments. In the environment, sensor nodes can easily be compromised by adversaries to generate injecting false data attacks. The injecting false data attack not only consumes unnecessary energy in en-route nodes, but also causes false alarms at the base station. To detect this type of attack, a bandwidth-efficient cooperative authentication (BECAN) scheme was proposed to achieve high filtering probability and high reliability based on random graph characteristics and cooperative bit-compressed authentication techniques. This scheme may waste energy resources in en-route nodes due to the fixed number of forwarding reports. In this paper, our proposed method effectively selects a dynamic number of forwarding reports in the source node...
