Security in Wireless Sensor Networks - A Study
نویسندگان
چکیده
Wireless Sensor Networks (WSNs) are used in many commercial, military, industrial, research and medical applications. Because of the limited resources of the sensor nodes in the wireless environment, these networks impose special security requirements besides to the security needs in traditional networks. This study presents the security problems in WSNs and discusses the security protocols based on three different security mechanisms: Security Protocols for WSNs (SPINS), which uses symmetric key cryptography, then TinySec, which is based on Link layer encryption, and later TinyPK (the Public Key Infrastructure solution). This study also presents the security solutions offered, and also security problems not addressed, by these protocols.

Communication security of wireless sensor networks is achieved using cryptographic keys assigned to the nodes. Due to resource constraints in such networks, random key pre-distribution schemes are of high interest. Although in most of these schemes no location information is considered, there are scenarios that location information can be obtained by nodes after their deployment. In this paper,...
متن کاملAn efficient symmetric polynomial-based key establishment protocol for wireless sensor networks
An essential requirement for providing secure services in wireless sensor networks is the ability to establish pairwise keys among sensors. Due to resource constraints on the sensors, the key establishment scheme should not create significant overhead. To date, several key establishment schemes have been proposed. Some of these have appropriate connectivity and resistance against key exposure, ...
