Wireless sensor networks (WSNs) have recently attracted a lot of interest in the research community due their wide range of applications. Due to distributed nature of these networks and their deployment in remote areas, these networks are vulnerable to numerous security threats that can adversely affect their proper functioning. This problem is more critical if the network is deployed for some mission-critical applications such as in a tactical battlefield. Random failure of nodes is also very likely in real-life deployment scenarios. Due to resource constraints in the sensor nodes, traditional security mechanisms with large overhead of computation and communication are infeasible in WSNs. Security in sensor networks is, therefore, a particularly challenging task. This paper discusses the current state of the art in security mechanisms for WSNs. Various types of attacks are discussed and their countermeasures presented. A brief discussion on the future direction of research in WSN security is also included.

Theory and Practice of Cryptography Solutions for Secure Information Systems

Advances in electronics and wireless communication technologies have enabled the development of large-scale wireless sensor networks (WSNs). There is numerous applications for wireless sensor networks, and security is vital for many of them. However, WSNs suffer from many constraints, including low computation capability, small memory, limited energy resources, susceptibility to physical capture, the lack of infrastructure, which impose unique security challenges and make innovative approaches desirable. In this paper we present a survey of security issues in WSNs, address the state of the art in research on sensor network security, and discuss some future directions for research.

Sensor Networks have emerged as the next big thing to succeed in the times to come and it posed to dominate the trend of technology, however they bring in their own share of challenges. Most of these network consists of thousands or more of minute sensors that work independently. Limitation of cost availability and the requirement of abundant, undetectable placements would be resultant in small sensor node that have limited resources. We would be focusing on the security aspect of the set of sensors in a network, even though we know that there are a lot many challenges for the sensor networks. In this paper we would also suggest some of the goals for security of sensor networks. Furthermore, since security is a critical issue for the sensor networks being accepted and being used for many software applications, we would also attempt to analyze the threats against the Wireless Sensor Networks, in turn proposing some measure to counter the attacks against the Wireless Sensor Networks.

Wireless Sensor Network(WSN) is an emerging technology and explored field of researchers worldwide in the past few years, so does the need for effective security mechanisms. The sensing technology combined with processing power and wireless communication makes it lucrative for being exploited in abundance in future. The inclusion of wireless communication technology also incurs various types of security threats due to unattended installation of sensor nodes as sensor networks may interact with sensitive data and /or operate in hostile unattended environments. These security concerns be addressed from the beginning of the system design. The intent of this paper is to investigate the security related issues in wireless sensor networks. In this paper we have explored general security threats in wireless sensor network with extensive study.

Wireless sensor networks (WSNs) have attracted a lot of interest over the last decade in wireless and mobile computing research community. Applications of WSNs are numerous and growing, which range from indoor deployment scenarios in the home and office to outdoor deployment in adversary’s territory in a tactical battleground. However, due to distributed nature and their deployment in remote areas, these networks are vulnerable to numerous security threats that can adversely affect their performance. This problem is more critical if the network is deployed for some mission-critical applications such as in a tactical battlefield. Random failure of nodes is also very likely in real-life deployment scenarios. Due to resource constraints in the sensor nodes, traditional security mechanisms with large overhead of computation and communication are infeasible in WSNs. Design and implementation of secure WSNs is, therefore, a particularly challenging task. This chapter provides a comprehensive discussion on the state of the art in security technologies for WSNs. It identifies various possible attacks at different layers of the communication protocol stack in a typical WSN and presents their possible countermeasures. A brief discussion on the future direction of research in WSN security is also included.

Wireless Sensor Networks are extremely vulnerable against any kind of internal or external attacks, due to several factors such as resource-constrained nodes and lack of tamper-resistant packages. As a result, security must be an important factor to have in mind when designing the infrastructure and protocols of sensor networks. In this paper we survey the "state-of-the-art" security issues in sensor networks and highlight the open areas of research.

Wireless Sensor Networks (WSN) is a recent advanced technology of computer networks and electronics. The WSN increasingly becoming more practicable solution to many challenging applications. The sensor networks depend upon the sensed data, which may depend upon the application. One of the major applications of the sensor networks is in military. So security is the greatest concern to deploy sensor network such hostile unattended environments, monitoring real world applications. But the limitations and inherent constraints of the sensor nodes does not support the existing traditional security mechanisms in WSN. Now the present research is mainly concentrated on providing security mechanism in sensor networks. In this context, we analysis security aspects of the sensor networks like requirements, classifications, and type of attacks etc., in this survey paper.

Wireless sensor networks are comprised of large numbers of resource-constrained and wirelessly communicating computing devices. Advances in computing and communication technology have made it possible to integrate sensing capabilities, wireless communication interfaces, and microprocessors into tiny devices that allow to embed compuational power in arbitrary environments. The applications of wireless sensor networks range from surveillance and environmental monitoring to healthcare and the provisioning of context information for computing applications. Many of these applications have a direct impact on the welfare of human beings or are of high economic significance. Security breaches might lead to grave consequences, so it is important to protect wireless sensor networks against such threats.
