摘要：Large-scale wireless sensor networks are highly vulnerable to attacks because they consist of numerous resource-constrained devices and communicate via wireless links. As wireless sensor networks are continue to grow, so they need an effective security mechanisms. As sensor networks may interact with sensitive data and/or operate in hostile unattended environments, it is imperative that these security concerns must be addressed from the beginning of the system design. However due to inherent resource and computing constraints, security in sensor networks poses different challenges than traditional network computer security. Here we describe an energy efficient security scheme for sensor networks that is designed for long lived networks. Primary features of our scheme include autonomously computing administration keys and dynamically mapping of sensor nodes to set of keys. The scheme scales well in the size of the network and supports dynamic setup and management of arbitrary structures for secure communications in large-scale wireless sensor network. A salient feature of the security scheme is that, it supports source authentication as well as end-to-end authentication, integrity of communication, efficiently addition of the sensor nodes to the network dynamically.
