ISO/IEC 24824-3:2008规定了对使用ISO/IEC 24824-1中的fast信息集规范序列化的XML信息集片段应用加密和完整性（单独或组合）。加密规范使用W3C建议的XML加密语法和处理。完整性规范使用了W3C建议W3C规范化XML版本1.0、W3C独占XML规范化版本1.0以及XML签名语法和处理。

ISO/IEC 24824-3:2008 specifies the application of encryption and integrity (either separately or in combination) to a fragment of an XML infoset that is serialized using the fast infoset specification in ISO/IEC 24824-1. The specification of encryption uses the W3C Recommendation XML Encryption Syntax and Processing. The specification of integrity uses the W3C Recommendations W3C Canonical XML Version 1.0, W3C Exclusive XML Canonicalization Version 1.0, and XML-Signature Syntax and Processing.
