TrustZone is a system-wide hardware isolation achieved by separating the CPU into the Normal World and the Secure World. The Normal World contains and executes the main operating system, also called the Rich OS (e.g. Android, GNU/Linux, etc.), which the user primarily interacts with and which performs all the non-sensitive tasks.
Trust.Zone has three paid packages – monthly, 3-monthly, and yearly. There is also a free package that offers 1GB for 3 days. You can access 108 locations and get unlimited bandwidth. Once you’ve exhausted the trial, you’ll need to move to a paid plan. A Trusted Execution Environment (TEE) is an environment where the code executed and the data accessed is isolated and protected in terms of confidentiality (no one have access to the data) and integrity (no one can change the code and its behavior). REE, like jailbreaking on iOS or rooting on Android. Second, the TEE has higher privilege than REE, which enables it to monitor and check the REE’s running status, like scanning all the REE memory for intrusion detection, integrity enforcement and so on. One challenge is the semantic gap between TEE and REE since TEE can only access the TrustZone hardening is a crucial point in order to obtain good security properties and slow down the reverse engineering and exploitation process. Nonetheless, several classic hardening points, listed below, are not applied: Both implementations have many debugging strings present in production.

TrustZone technology is tightly integrated into the A7 processor and extends throughout the system via the AMBA AXI bus and specific TrustZone System IP blocks. This system approach means that it is possible to secure peripherals such as secure memory, crypto blocks, keyboard, screen and sensors to ensure they can be protected from software attack.

Jun 01, 2019 · As described in Fig. 1, ARM TrustZone is an ARM processor-based security extension designed to provide the TEE to devices.By orchestrating the TrustZone hardware components, it enables system on chip (SoC) designers to divide the system into two environments: the REE and the TEE.

[PATCH v2 0/9] staging: ccree: add Arm TrustZone Arm TrustZone CryptoCell 700 is a family of cryptographic hardware accelerators. It is supported by a long lived series of out of tree drivers, which I am now in the process of unifying and upstreaming. This is the first drop, supporting the new CryptoCell 712 REE. The code still needs some cleanup before maturing to … In TrustZone terminology, this entire environment is referred to as the Rich Execution Environment (REE). By contrast, the TrustZone virtual core hosts and runs a Trusted Execution Environment (TEE) in the “Secure World” (SWd). In practice, TrustZone virtual cores are implemented by fast context switching performed inside the Secure Monitor.
