White paper: How should an RTOS work in a TrustZone for
Arm TrustZone technology is used on billions of applications processors to protect high-value code and data. Within Arm Cortex-A processors, software either resides in the secure world or the non-secure world; a switch between the two is accomplished via software referred to as the secure monitor. iOS Device Protection Review -1. TrustZone ARM TrustZone technology is a system-wide approach to security based on client and server computing platforms. TrustZone's hardware capability is represented at software layer by a two-world architecture: normal world and secure world (See Fig. 1). AMD Secure Technology: Ultimate Protection | AMD ARM® TrustZone®, a system-wide approach to security, runs on top of the hardware creating a secure environment by partitioning the CPU into two virtual “worlds.” Sensitive tasks are run on the AMD Secure Processor – in the “secure world” – while other tasks are run in “standard operation.” This helps ensure the secure storage security - ARM TrustZone's Secure/Normal world vs. OS's
Check Point: Qualcomm TrustZone flaws could be 'game over'
In TrustZone, there are two worlds, the Normal World, and the Secure World. Virtually all smartphone software as we know today still runs in Normal World. The Secure World is reserved for highly sensitive computations, and is used extensively by Knox for protecting enterprise confidential data. Embedded Security with Arm TrustZone - Mentor Graphics Software that is designated as secure world software has access to all of the hardware IP present in the SoC, while software that is designated as normal world software, can only access those hardware elements that are defined as normal or “non-secure”. As powerful as Arm TrustZone is, it needs additional software support to effectively
The TrustZone architecture provides a means for system designers to help secure systems, using the TrustZone Security Extensions, and Secure peripherals. Low-level programmers should understand the design requirements that are placed on the system by the TrustZone architecture, even if they do not use the security features. A Secure design
