Design of Lightweight Secure and Distributed Reprogramming Protocol for Wireless Sensor Networks using Identity-Based Signature Scheme

A novel secure and distributed reprogramming protocol called SDRP is the prime distributed reprogramming protocol for Wireless Sensor Networks (WSNs). SDRP relies on distributed reprogramming approach that permits multiple authorized network users to directly and simultaneously update program images on different sensor nodes without including the base station. SDRP expands Deluge to be a secure protocol but Deluge becomes inefficient with respect to delay, communication and energy to high network density. A new improved SDRP using identity-based short signature scheme has been designed. Rateless Deluge has many benefits as compared to Deluge such as minimizing latency at reasonable levels of packet loss, generally utilizing much less energy, and being more scalable to high network density, a major resource in WSNs. Therefore, for further improvement of the reprogramming efficiency of improved SDRP in terms of delay, communication and energy, present work is based on how to integrate improved SDRP with a better reprogramming protocol like Rateless Deluge, which leads to lightweight secure and distributed reprogramming.
