ISO/IEC 11889-1:2015定义了可信平台模块（TPM）的体系结构元素，TPM是一种能够在一般计算平台上实现信任的设备。一些TPM概念在TPM本身的上下文中得到了充分的解释。其他TPM概念将在TPM如何帮助在计算平台中建立信任的上下文中进行解释。当描述TPM如何帮助建立对计算平台的信任时，ISO/IEC 11889-1:2015为平台要求提供了一些指导。然而，ISO/IEC 11889的范围仅限于TPM要求

ISO/IEC 11889-1:2015通过使用加密技术说明了平台环境中的TPM安全和隐私技术。 它包括TPM如何实现不同加密技术的定义。ISO/IEC 11889的范围不包括密码分析或关于不同算法在特定使用情况下适用性的指南

ISO/IEC 11889-1:2015中的TPM要求是通用的，涵盖完整性保护、隔离和保密等概念。定义特定的功能强度或保证级别超出了ISO/IEC 11889的范围。这种方法限制了ISO/IEC 11889本身提供的保证，但它确实允许对定义的TPM体系结构元素进行调整，以满足不同的实施和特定于平台的需求。

ISO/IEC 11889-1:2015 defines the architectural elements of the Trusted Platform Module (TPM), a device which enables trust in computing platforms in general. Some TPM concepts are explained adequately in the context of the TPM itself. Other TPM concepts are explained in the context of how a TPM helps establish trust in a computing platform. When describing how a TPM helps establish trust in a computing platform, ISO/IEC 11889-1:2015 provides some guidance for platform requirements. However, the scope of ISO/IEC 11889 is limited to TPM requirements.

ISO/IEC 11889-1:2015 illustrates TPM security and privacy techniques in the context of a platform through the use of cryptography. It includes definitions of how different cryptographic techniques are implemented by a TPM. The scope of ISO/IEC 11889 does not include cryptographic analysis or guidance about the applicability of different algorithms for specific uses cases.

TPM requirements in ISO/IEC 11889-1:2015 are general, covering concepts like integrity protection, isolation and confidentially. Defining a specific strength of function or assurance level is out of scope for ISO/IEC 11889. This approach limits the guarantees provided by ISO/IEC 11889 itself, but it does allow the TPM architectural elements defined to be adapted to meet diverse implementation and platform specific needs.
