Secure Lightweight Stream Data Outsourcing for Internet of Things

The epoch of the Internet Things (IoT) has come by enabling almost everything to gather and share electronic information. Considering unreliable factors public IoT, how outsource huge amounts indispensable stream data generated nodes remote storage (RS) efficiently securely is one most challenging issues. In this article, we propose a secure lightweight outsourcing framework for IoT based on identity blockchain. Taking advantage identity-based cryptography blockchain, containing untrusted communication channels, nodes, RS, even verifiers, introduce private mobile network multiple verifiers ensure that are stored intact updated correctly, without costs risks brought public-key infrastructures (PKI). Meanwhile, can also achieve privacy-preserving checking, revealing no other entities besides in blockchains. Our comprehensive analysis experiments demonstrate proposed suitable devices practical IoT.
