A Protocol for Confidential and Distributed Reprogramming in Wireless Sensor Networks
Abstract: A wireless sensor network (WSN) consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure. and to cooperatively pass their data through the network to a main location. The process of uploading new code or changing the functionality of existing code is called Wireless reprogramming. For security reasons, every code update must be authenticated to prevent an adversary from installing malicious code in the network. All existing reprogramming protocols are based on the centralized approach in which only the base station has the authority to initiate reprogramming. This project develops A Protocol for confidential and distributed reprogramming in WSN named PCDR. The protocol uses identity-based cryptography to secure the reprogramming and to reduce the communication and storage requirements of each node.
