A Fundamental Analysis of Caching Data Protection Scheme using Light-weight Blockchain and Hashchain for Information-centric WSNs

This paper explains a novel caching data protection scheme that uses lightweight blockchain and hashchain for information-centric wireless sensor networks. The proposed verification procedure in a Blockchain is conducted based on the proof-of-consensus validation mechanism without using exhaustive mining computations; therefore, our scheme is suitable for resource-shortage wireless and mobile devices. Hashchains are utilized for traceability and signatures that ensure a block’s validity. We make a primitive evaluation of the scheme using computer simulations in familiar low-power wide-area wireless environments.
