Secure Strategy for Key Pre-Distribution in Wireless Sensor Networks
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2016, Vol 18, Issue 5
Abstract
Abstract: Wireless sensor networks (WSN) are a collection of sensor nodes, which is deployed spatially among various environments. WSNs are deployed in environments where wired networks are difficult to set up. They are mainly used to record sensitive information regarding physical or environmental conditions. As they collect sensitive information, secure and accurate transmission of data is important. For secure transmission of data, key management is a corner stone in wireless sensor networks. Wireless sensor networks are infrastructure less. Due to this reason, key distribution among increasing number of nodes by third parties is a challenging problem. Hence, symmetric key pre-distribution algorithms areintroduced for key distribution. However, most schemes suffer from low scalability, high storage overhead and it is difficult to implement security with existing solutions. In order to provide good key sharing and secure connectivity, an asymmetric algorithm called elliptical curve cryptography (ECC) will be used. After collecting data from deployed environment, sensor nodes will send data to sink node, which receives data and process the information. Data will be routed to sink node in secure environment using shortest path routers. The schemes will be implemented in java programming language and results would be derived to show/compared for more efficiency in terms of secure connectivity, storage overhead, computational cost and communication cost.
