Secure Mechanism For Wireless Sensor Networks - A Review

Wireless Sensor Network (WSN) is an emerging technology that is very usefu l for various futuristic applications both for public and military. As the use of wireless sensor networks continue to grow, so it should require effective security mechanisms. So to ensure the security of communication and data access control in WSN is paramount importance. Because sensor networks may interact with sensitive data and operate in hostile unattended environments, it is important that these security concerns should be addressed from the beginning of the system design. However because of inh erent resource and computing constraints, security in sensor networks poses different challenges than traditional network security. There is currently enormous research is present in the field of wireless sensor network security. Thus, familiarity with t he wireless sensor network,attack on WSN and security systems design for WSN will benefit researchers greatly. With this in mind , I survey the major topics in wireless sensor network security, and presentmany of the current attacks, and finally list their corresponding defensive measure

Security wireless sensor networks: prospects, challenges, and future

With the advancements of networking technologies and miniaturization of electronic devices, wireless sensor network (WSN) has become an emerging area of research in academic, industrial, and defense sectors. Different types of sensing technologies combined with processing power and wireless communication capability make sensor networks very lucrative for their abundant use in near future. However, many issues are yet to be solved before their full-scale practical implementations. Among all the research issues in WSN, security is one of the most challenging topics to deal with. The major hurdle of securing a WSN is imposed by the limited resources of the sensors participating in the network. Again, the reliance on wireless communication technology opens the door for various types of security threats and attacks. Considering the special features of this type of network, in this chapter we address the critical security issues in wireless sensor networks. We talk about cryptography, steganography, and other basics of network security and their applicability in WSN. We explore various types of threats and attacks against wireless sensor networks, possible countermeasures, mentionable works done so far, other research issues, etc. We also introduce the view of holistic security and future trends towards research in wireless sensor network security

WISP: a wireless information security portal

M.Sc.Wireless networking is a fairly new technology that is important in information technology (IT). Hotels, Airports, Coffee shops, and homes are all installing wireless networks at a record pace, making wireless networks the best choice for consumers. This popularity of wireless networks is because of the affordability of wireless networks devices, and the easy installation [11]. In spite of the popularity of the wireless networks, one factor that has prevented them from being even more widespread can be summed up in a single word: security. It comes as no surprise that these two – wireless and security – converge to create one of the most important topics in the IT industry today [11]. Wireless networks by nature bring about new challenges unique to its environment. One example of these new challenges is: “Signal overflow beyond physical walls”, and with these kinds of new challenges unique to wireless networks, we have new security risks. Hence wireless networks lend themselves to a host of attack possibilities and risks. That is because wireless networks provide a convenient network access point for an attacker, potentially beyond the physical security controls of the organization [7]. Therefore it is challenging for managers to introduce wireless networks and properly manage the security of wireless networks, Security problems of wireless networks are the main reason for wireless networks not being rolled out optimally [1]. In this dissertation, we aim to present to both specialist and non–specialists in the IT industry the information needed to protect a wireless network. We will first identify and discuss the different security requirements of wireless networks. After that we shall examine the technology that helps make wireless networks secure, and describe the type of attacks against wireless networks and defense techniques to secure wireless networks. The research will concentrate on wireless LANs (Local Area Networks), and leading wireless LAN protocols and standards. The result of the research will be used to create WISP (A Wireless Information Security Portal). WISP will be a tool to support the management of a secure wireless network, and help assure the confidentiality, integrity, and availability of the information systems in a wireless network environment

Free Tools for Teaching & Researching Wireless Networking Concepts

As wireless networking and security become more prevalent in the market, more and more computer science programs are incorporating courses in wireless networks or at the least, devoting a significant percentage of the advanced networking courses to wireless topics. As a result, in addition to industry practitioners, there is a growing interest among university researchers and faculty regarding tools used for teaching and researching in wireless networking concepts.This tutorial will demonstrate two free tools, Network Stumbler and ITGuru\u27s wireless module (academic version is free)

Mobile Ad-Hoc Networks

Being infrastructure-less and without central administration control, wireless ad-hoc networking is playing a more and more important role in extending the coverage of traditional wireless infrastructure (cellular networks, wireless LAN, etc). This book includes state-of the-art techniques and solutions for wireless ad-hoc networks. It focuses on the following topics in ad-hoc networks: vehicular ad-hoc networks, security and caching, TCP in ad-hoc networks and emerging applications.

Access Point Security Service for wireless ad-hoc communication

This paper describes the design and implementation of a security solution for ad-hoc peer-to-peer communication. The security solution is based on a scenario where two wireless devices require secure communication, but share no security relationship a priori. The necessary requirements for the security solution described here comprise topics such as energy efficiency, security standards and ad-hoc networks. The devised solution is called Access Point Security Service (APSS). APSS is able to provide security by delivering a symmetric key to two wireless devices that require ad-hoc peer-to-peer communication. The main principle of APSS is that it makes use of an existing security relationship between a network provider and its customers. The existing security relationship enables the network provider to deliver security to two or more communicating parties in the form of a shared key. An implementation of APSS is provided making use of the existing Wi-Fi security standards
