Smart-Zone - A design for Memory efficient & secure DNN inference on TrustZone-enabled Consumer IOT devices



Trusted Execution Environments (TEEs) & Regular Execution Environments (REEs) in modern OS systems.


Approaches tried so far - task offloading & model partitioning


Core problem of safe & efficient model inference is not solved as each of above approaches are vulnerable and inefficient.


Smart-Zone architecture proposed here solves these problems using new design


How Smart-Zone design works


Performance results - Smart-Zone improves inference speed by 3.13 times while reducing power consumption by 66.5%.
