Security in wireless sensor networks

Computational Science and Its Applications – ICCSA 2005, 2005

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.

Security is a crucial service in wireless sensor networks that is becoming increasingly common in WSNs because wireless sensor nodes are typically deployed in an unattended environment, leaving them open to possible hostile network attack. Because wireless sensor nodes are limited in computing power, data storage and communication capabilities, any user authentication protocol must be designed to operate efficiently in a resource constrained environment. With a widespread growth in the potential applications of WSN, the need for reliable security mechanisms for them has increased manifold. Security protocols in WSNs, unlike the traditional mechanisms, need special efforts and issues to be addressed. The set of challenges in sensor networks are diverse, we focus on attacks on Wireless Sensor Network in this paper.

Wireless Sensor Networks (WSN) is an emerging technology that shows great promise for various futuristic applications. As wireless sensor networks continue to grow, for the needs of effective security mechanisms. A wireless sensor network may comprise thousands of sensor nodes. Each sensor node has a sensing capability as well as limited energy supply, compute power, memory and communication ability. Sensor nodes can be used for continuous sensing, event detection, event ID, location sensing and local control of actuators. However, realizing the full potential of wireless sensor networks poses myriad research challenges ranging from hardware and architectural issues. In this paper we analyze the security attacks in wireless sensor networks.

Wireless Sensor Network is a gathering of sensors with incomplete resources that collaborate in order to achieve a shared goal. It is susceptible to node capture attacks because sensor nodes are deployed in unattended manner. Once opponent imprisonments sensor nodes, he can compromise that node and presentation various types of occurrences with those compromised nodes. The antagonist takes the secret keying possessions from a compromised node, generates a large number of attacker-controlled imitations that share the cooperated node's keying materials and ID, and then feasts these replicas throughout the system. Therefore, captivity node attacks are perilous and should be noticed that node to reduce the harm. Several replica node detection schemes have been proposed against these attacks in static instrument networks. These methods are worked only in static sensor network and hence do not work in mobile sensor networks. In this work, propose a fast and effective mobile replication node discovery scheme using event-based attack decomposition. It shows logically and through imitation experimentations that our scheme detects mobile imitations in an efficient and robust method at the cost of judicious expenses.

Wireless sensor networks (WSNs) have many potential applications [1, 5] and unique challenges. They usually consist of hundreds or thousands small sensor nodes such as MICA2, which operate autonomously; conditions such as cost, invisible deployment and many application domains, lead to small size and limited resources sensors [2]. WSNs are susceptible to many types of physical attacks [1] and most of traditional networks security techniques are unusable on WSNs[2]; due to wireless and shared nature of communication channel, untrusted transmissions, deployment in open environments, unattended nature and limited resources [1]. So, security is a vital requirement for these networks; but we have to design a proper security mechanism that attends to WSN's constraints and requirements. In this paper, we focus on security of WSNs, divide it (the WSNs security) into four categories and will consider them, include: an overview of WSNs, security in WSNs, the threat model on WSNs, a wide v...
