Advancement Through Research
Wireless Sensor Networks (WSNs) comprised of numerous spatially scattered autonomous devices that receive and transmit data using an insecure wireless channel. A sensor network is one of key development technology for IoT standards. It enables cooperation of heterogeneous information among devices and services. Security in wireless communication is a major concern not only for authenticated sources but also for transfer consistent data from sender nodes to base station while maintains network obtainability. Linked timestamping generates hashed timestamps, which is hooked on prior timestamps in authentic way. A slight change in timestamps value cancels the linked timestamps block. The serial order of linked timestamps is also saved by making backdating of the issued timestamp. The proposed method uses hashed linked timestamp authentication and is based on current timestamp in which information is encrypted with strong public-key cryptography for every sensor node. Therefore, it makes feasible to defend against various active and passive attacks. Complexity analysis has been done to show the superiority of the proposed approach.
