MINImathsizesmallTEE—A Lightweight TrustZone-Assisted TEE for Real-Time Systems

While trusted execution environments (TEEs) provide industry standard security and isolation, TEE requests through secure monitor calls (SMCs) attribute to large time overhead and weakened temporal predictability. Moreover, as current available TEE solutions are designed for Linux and/or Android ini...
