Defending Real-Time Systems through Timing-Aware Designs
… defense strategy for the CAN bus that utilizes TrustZone on state-of-the-art ARMv8-M microcontrollers. The second reduces the runtime cost of control-flow integrity (CFI), a popular system security defense technique, by correctly modeling when a real-time system performs I/O, and exploiting the …

The Art of SRAM Security: Tactics for Remanence-based Attack and Strategies for Defense
… subjected to inspections by authorities. 3. UntrustZone utilizes long-term data remanence to exfiltrate secrets from on-chip SRAM. An attacker application must be able to read retained states in the SRAM upon power cycles, but this needs changing the security privilege. Hardware security …
