MVAM: Multi-variant Attacks on Memory for IoT Trust Computing. (arXiv:2301.04591v1 [cs.CR])

With the significant development of the Internet of Things and low-cost cloud
services, the sensory and data processing requirements of IoT systems are
continually going up. TrustZone is a hardware-protected Trusted Execution
Environment (TEE) for ARM processors specifically designed for IoT handheld
systems. It provides memory isolation techniques to protect trusted application
data from being exploited by malicious entities. In this work, we focus on
identifying different vulnerabilities of the TrustZone extension of ARM
Cortex-M processors. Then design and implement …
