Abstract:
Internet of things is widespread in our daily life, such as smart cities (homes), health care, and our activity lifelogs. In these use cases, sensing data must be managed not only effectively but also securely. From this perspective, we adopt the information-centric network design into wireless sensor networks for efficient peer-to-peer data collection, delivery, and publication. In the study of information-centric schemes, caching technology is significantly important; thus, we focus on a secure caching mechanism to privacy and security protections. In particular, the caching data protection mechanism, i.e., to prevent cache pollution attacks, is an essential challenge for data retrieving in information-centric wireless sensor networks. In this paper, therefore, we propose a novel effective and secure caching scheme for wireless sensor networks using the information-centric network design and the blockchain technology. In particular, for caching data management, to maintain the blockchain-based ledger requires exhaustive computer calculation resources and energy consumption in mining-based verification tasks; nevertheless, resource-limited wireless node devices are not suitable. Therefore, we propose a novel light-weight verification mechanism based on proof-of-consensus, and we reveal its fundamental features using computer simulation.
