BRICS: Blockchain-based Resilient Information Control System
Tiffany Hyun‐Jin Kim, Joshua Lampkins · 2018
This paper introduces a system for providing integrity, authenticity, and privacy of data transactions for resource-limited Internet of Things (IoT) smart devices using blockchain (BC) and Multi-Party Computation (MPC). In particular, we introduce two mechanisms: one provides privacy and integrity protections on the data being collected by the smart devices, such as medical records or diagnostic data, and the other provides authenticity and integrity of data going into the smart devices, such as software updates. Our experimental results indicate that our proposed mechanisms incur small overhead in terms of storage, communication, and computation, indicating their feasibility to IoT devices with limited storage, computational, and communicational capabilities.
