適用范圍：ISO/IEC 11889 defines the Trusted Platform Module (TPM), a device that enables trust incomputing platforms in general. ISO/IEC 11889 is broken into parts to make the role of eachdocument clear. Any version of the standard requires all parts to be a complete standard.A TPM designer MUST be aware that for a complete definition of all requirements necessary tobuild a TPM, the designer MUST use the appropriate platform specific specification to understandall of the TPM requirements.Part 2 defines the principles of TPM operation. The base operating modes, the algorithms and keychoices, along with basic interoperability requirements make up the majority of the normativestatements in part 2.1.1 Key wordsThe key words “MUST,” “MUST NOT,” “REQUIRED,” “SHALL,” “SHALL NOT,” “SHOULD,”“SHOULD NOT,” “RECOMMENDED,” “MAY,” and “OPTIONAL” in this document’s normativestatements are to be interpreted as described in RFC-2119, Key words for use in RFCs to IndicateRequirement Levels.1.2 Statement TypePlease note a very important distinction between different sections of text throughout this document.You will encounter two distinctive kinds of text: informative comment and normative statements.Because most of the text in this specification will be of the kind normative statements, the authorshave informally defined it as the default and, as such, have specifically called out text of the kindinformative comment They have done this by flagging the beginning and end of each informativecomment and highlighting its text in gray. This means that unless text is specifically marked as ofthe kind informative comment, you can consider it of the kind normative statements.For example:Start of informative commentThis is the first paragraph of 1–n paragraphs containing text of the kind informative comment ...This is the second paragraph of text of the kind informative comment ...This is the nth paragraph of text of the kind informative comment ...To understand the standard the user must read the standard. (This use of MUST does not requireany action).End of informative commentThis is the first paragraph of one or more paragraphs (and/or sections) containing the text of thekind normative statements ...To understand the standard the user MUST read the standard. (This use of MUST indicates akeyword usage and requires an action).
