Wireless sensor networks (WSNs) have the potential to be widely used in many areas for unattended event monitoring. Mainly due to lack of a protected physical boundary, wireless communications are vulnerable to unauthorized interception and detection. Privacy is becoming one of the major issues that jeopardize the successful deployment of wireless sensor networks. While confidentiality of the message...
Recently, System-on-Chip (SoC) technology has been adopted to design smaller, lower-power and cheaper tamper-resistant sensor nodes. In these nodes, we find that there exists a lifetime-secure memory fraction which stores the anterior part of the application executable binary code, namely "fingerprint". We propose a key management protocol based on this secure finger- print-FKM. In this...
Secure authentication in wireless sensor networks is complicated by the promiscuous nature of the wireless transmission medium and by the limited hardware and software capabilities of the nodes in such networks. We analyze the requirements for using RF fingerprints to initialize secure authenticated links in a wireless sensor network for a surveillance application that allows older people to remain...
Key management is deemed as the fundamental essential part of any secure communication. A secure sensor network communication protocol relies on the substantial secure, robust and efficient key management system. We put forward a new hybrid group key management scheme for hierarchical self organizing wireless sensor network architecture. By using this approach, multi-level security can be achieved...
A low-power sensor node in WSN requires minimum consumption of energy. It is essential to establish key to reduce the effect when the sensor node is revealed. This paper propose the protocol of pairwise key establishment between sensor node. The proposed method increases the availability by clustering the network in three dimensional, which has smaller number of path and better energy efficiency than...
Sensor networks pledge to solve many monitoring problems: thousands of small inexpensive devices can be easily deployed in any environment and can provide measurements about diverse phenomenons, such as temperature, pollution, birds migration, etc. As sensors are low-capabilities, battery powered devices, several protocols have been proposed to maximize their lifetime, but only recently research has...
