Arm TrustZone technology is a system-on-chip (SoC) and CPU system-wide approach to security with hardware-enforced isolation to establish secure end points and a device root of trust. Investigation of MBED Operating system with Trustzone as Also, perform MBED with TrustZone operations and system performance. On the security side, trust zone is to be investigated to see if it is suitable to be used in cellular IoT system. The outcome would be to understand how a cellular IoT system would be affected in the relation to adding this trust zone features. Working towards Mbed TLS 3.0 - Tech Updates - Mbed TLS

Trusted Firmware

System-Wide Security for IoT Devices TrustZone technology for Arm Cortex-M processors enables robust levels of protection at all cost points for IoT devices. The technology reduces the potential for attack by isolating the critical security firmware, assets and private information from the rest of the application.

TrustZone use case and trend (FFRI Monthly Research Mar 2017) Apr 17, 2017 Side-channel attack on ECC key import and - Mbed TLS Vulnerability. The scalar multiplication function in Mbed TLS accepts a random number generator (RNG) as an optional argument and, if provided, uses it to protect against some attacks, including a previous attack by the same authors.. It is the caller's responsibility to provide a RNG if protection against side-channel attacks is desired; however two groups of functions in Mbed TLS itself fail Arm Mbed Cloud Services The Arm Mbed Security platform has trust managed from the cloud but enforced by the device based on Arm® TrustZone®, which separates secure and non-secure worlds in hardware, and keeps non-secure software blocked from accessing secure resources directly.
