Approximate Computing (AC) techniques trade accuracy for performance improvement and energy efficiency, being increasingly attractive in various computation-intensive applications such as imaging processing, audio recognition, information search, and artificial intelligence. However, recent literature indicates that the utilization of AC techniques may raise new and unique security concerns. This project investigates hardware (HW) and software (SW) integrated methods to secure AC systems.
