Secure Data Collection, Storage and Access in Cloud-Assisted IoT

The cloud-assisted Internet of Things (IoT) provides a promising solution to data booming problems for the ability constraints of individual objects. However, with the leverage of cloud, IoT faces new security challenges for data mutuality between two parties, which is introduced for the first time in this paper and not currently addressed by traditional approaches. We investigate a secure cloud-assisted IoT data managing method to protect data confidentiality when collecting, storing, and accessing IoT data while limiting to effects of IoT scalability. We further present numerical results to show that the method is practical.
