STRAIT: Secure and Privacy-Customisable Data Transmission for Internet-of-Things

Technology Overview

The growth of smart, autonomous and connected devices in our everyday lives is also punctuated by the vulnerability of these systems towards malicious attacks, capturing sensitive private data or sending fraudulent, unauthenticated information. Furthermore, privacy-aware citizenry often contests the intrusion of such devices, thereby limiting their applicability. Therefore, future smart devices should also possess two important features namely, end-to-end security and customisable privacy. We intend to address this growing segment by presenting a secure sensing platform. Using our novel end-to-end security and customisable privacy technologies integrated with an advanced compressive sensing algorithm, we are able to secure the transmission and significantly reduce the volume of data to be transmitted. The entire platform is designed for a resource-constrained environment and can run on very low power/energy budget.
