Using Hardware-aided Trusted Execution Technology to Secure IoT Data Processing
Monday March 11, 2019 / 813 Rhodes / 11am – 12.30pm
Internet of Things intertwines the physical and cyber worlds and is designed to control critical aspects and functions of our daily life. With the rapid growth of IoT devices that usually operate on low power consumption mode with constrained resources and produce an enormous amount of sensitive data, the software-based cryptographic approach currently is often inadequate or even not applicable to meet a variety of requirements for secure IoT data processing. In this talk, I will introduce our recent work that exploits the advance of hardware-based trusted execution technology to build secure, performant and unified IoT data processing framework. The proposed framework enables a broad range of IoT application services. Specifically, we will target one of the fundamental data services, search function, to demonstrate its satisfactory performance with our implementation. In addition, we also consider the challenging service revocation problem and present solutions in a hostile environment where system resources are controlled by malicious adversaries. I will also discuss the insufficiency by using conventional “divide-and-conquer” strategy to compartmentalize/eliminate the individual threat and show the urgent need for innovative solutions with emerging technologies.
