Talos: Encrypted Query Processing for the Internet of Things

摘要: The Internet of Things, by digitizing the physical world, is envisioned to enable novel interaction paradigms with our surroundings. This creates new threats and leads unprecedented security privacy concerns. To tackle these concerns, we introduce Talos, a system that stores IoT data securely in Cloud database while still allowing query processing over encrypted data. We this encrypting set cryptographic schemes such as order-preserving partially homomorphic encryption. In order achieve constrained devices, Talos relies on optimized algorithms accelerate encryption 1 2 orders magnitude. assess feasibility low-power devices without accelerators quantify its overhead terms energy, computation, latency. With thorough evaluation prototype implementation, show practical can provide high level reasonable overhead. envision an enabler secure applications.
