摘要
ARM TrustZone[1]是一种基于硬件的安全特性，可以为软件提供高特权和隔离的执行环境。这种隔离是由硬件保证的，通常认为硬件比软件更值得信赖。因此，执行环境也称为可信执行环境(TEE)。TrustZone技术于2002年提出，但直到2009年苹果发布iPhone 5s才得到广泛应用。在iPhone 5s中，苹果利用TrustZone来保护其Touch ID，这确保了即使iOS完全被攻破，用户的指纹数据仍然是安全的。2017年，谷歌将TEE作为任何带有指纹扫描仪的安卓设备的强制性要求。如今，几乎所有的手机和平板电脑都配置了TEE。同时，ARM在ARM64和ARMv8-M中集成了TrustZone，以支持更广泛的平台，包括服务器和物联网设备。
ARM TrustZone [1] is a hardware-based security feature that can provide software with a high-privilege and isolated execution environment. Such isolation is ensured by hardware, which is usually considered as more trustworthy than software. Thus the execution environment is also known as trusted execution environment (TEE). TrustZone technology was proposed in 2002, but did not get widely used until 2009, when Apple released iPhone 5s. In iPhone 5s, Apple leveraged TrustZone to protect its Touch ID, which ensures that even if the iOS is fully compromised, the user's fingerprint data can still be safe. In 2017, Google made TEE a mandatory requirement on any Android devices with a fingerprint scanner. Nowadays, almost all mobile phones and tablets have TEE deployed. Meanwhile, ARM integrates TrustZone in ARM64 and ARMv8-M to support a broader range of platforms including servers and IoT devices.
