ISO/TR 19038:2005为用户提供技术支持和细节，以安全高效地实施三重数据加密算法（TDEA）操作模式，增强数字数据的加密保护。其中描述的操作模式是针对加密和解密操作而规定的。本技术报告中描述的模式是使用ISO/IEC 18033-3中规定的三重DEA算法（TDEA）实现ISO/IEC 10116中规定的分组密码操作模式。 TDEA操作模式可用于批发和零售金融应用。ISO/TR 19038:2005的使用为产品的互操作性提供了基础，并促进了使用TDEA操作模式的应用标准的开发。本技术报告旨在与使用DEA的其他ISO标准一起使用。

ISO/TR 19038:2005 provides the user with technical support and details for the safe and efficient implementation of the Triple Data Encryption Algorithm (TDEA) modes of operation for the enhanced cryptographic protection of digital data. The modes of operation described therein are specified for both enciphering and deciphering operations. The modes described in this Technical Report are implementations of the block cipher modes of operation specified in ISO/IEC 10116 using the Triple DEA algorithm (TDEA) specified in ISO/IEC 18033-3. The TDEA modes of operation may be used in both wholesale and retail financial applications. The use of ISO/TR 19038:2005 provides the basis for the interoperability of products and facilitates the development of application standards that use the TDEA modes of operation. This Technical Report is intended for use with other ISO standards using DEA.
