Security-enhanced Search Engine Design in Internet of Things

This paper elaborates the challenges in searching imposed by the burgeoning field of Internet of Things (IoT). Firstly it overviews the evolution of the new field to its predecessors: searching in the mobile computing, ubiquitous computing and information retrieve. Then, it identifies five research thrusts: architecture design, search locality, real-time, scalability and divulging information. It also sketches several presumptive IoT scenarios, and uses them to identify key capabilities missing in today’s systems. On top of these challenging issues, we report our undertaking work — a security-enhanced search engine for Internet of Things based on Elliptic Curve Cryptography (ECC) security protocol. We also report our preliminary experimental results.
