A semi-outsourcing secure data privacy scheme for IoT data transmission

Deploying trusted (private) cloud computing to exchange, store and analyse data from IoT networks has become mainstream. In this paper, we describe a data privacy transmission scheme for IoT data collection, which supports one-way identity authentication and a dual data integrity validation for low resource devices called the Lo-A&DI (Low-resource for IoT 1-way Authentication and Dual Integrity) scheme. Unlike other schemes that use trusted clouds, the Lo-A&DI can be applied to untrusted public clouds while protecting data security and privacy. Unlike other untrusted cloud security schemes, the Lo-A&DI scheme can be used to support end-to-end data security and privacy from low-resource ICT IoT devices. An experimental validation shows that the performance of the Lo-A&DI is much more adaptable for use in resource-constrained IoT devices when compared to a baseline trusted cloud scheme such as one based upon an interactive (2-way) certificate authentication scheme for IoT data exchange.
