Secure Privacy Data Collection, Storage and Access in Cloud-Assisted Internet of Things

Cloud-assisted Internet of Things (IoT) gives a promising answer for data blasting issues for the capacity imperatives of individual items. Notwithstanding, with the use of cloud, IoT faces new security challenges for data commonality between two gatherings, which is presented without precedent for this paper and not as of now tended to by customary methodologies. We explore a safe cloud-assisted IoT data overseeing technique to keep data confidentiality when gathering, putting away and getting to IoT data with the help of a cloud with the thought of clients' addition. The proposed framework novelly applies an intermediary reencryption plot, which was proposed in [5]. Subsequently, a safe IoT under our proposed technique could oppose most assaults from the two insiders and outcasts of IoT to break data confidentiality, and in the mean time with steady correspondence cost for re-encrytion against incremental size of IoT. We additionally demonstrate the strategy is viable by numerical outcomes.
