POSTER: Computations on Encrypted Data in the Internet of Things Applications

We identify and address two primary challenges for computing on encrypted data in Internet of Things applications: synchronizing encrypted data across devices and selecting an appropriate encryption scheme. We propose a caching mechanism that operates across the three devices, enabling interactive order-preserving encryption schemes on resource-constrained devices. Additionally, the system can use a high-level description of an IoT application to select automatically appropriate encryption for the data on corresponding tiers and their mathematical operations. This assists in fine-tuning and choosing the core parameters for underlying data structures.
