ISO/IEC 21277:2018定义了测试方法，以测量ISO/IEC 18000-63和ISO/IEC 29167（所有部分）中规定的用于项目管理的射频识别（RFID）设备（标签和询问器）加密套件的性能。 这些测试方法根据特定应用程序/服务所需的一组用例要求，根据加密套件结果测量加密套件系统性能（标签和询问器）。这些试验方法用作ISO/IEC 18046-1的扩展，但可以单独使用。 加密套件的性能在加密套件、标签和询问器的加密套件实现以及特定询问场景中的加密套件结果之间可能存在很大差异。标签加密功能需要时间和精力才能成功完成。 所需的加密强度和方法会影响所需的时间和能量。因此，本文件将“加密套件性能”定义为“相对于可用射频功率，在给定读取距离下完成加密结果的最短时间”。本文件提供了评估测量结果的指南。 测试方法不测量加密能力，包括加密强度、适用性和鲁棒性。它们既不测量随机生成器的性能，也不处理密钥管理。

ISO/IEC 21277:2018 defines test methods to measure the performance of crypto suites of radio frequency identification (RFID) devices (tags and interrogators) for item management as specified in ISO/IEC 18000？63 and ISO/IEC 29167 (all parts). These test methods measure the crypto suite system performance (tags and interrogators) against the crypto suite outcomes as required by the desired set of use case requirements for a specific application/service. These test methods are used as an extension of ISO/IEC 18046？1 but can be used in a standalone manner. Crypto suite performance can vary substantially between crypto suites, implementations of a crypto suite for tags and interrogators and crypto suite outcomes in specific interrogation scenarios. Tag crypto functions require time and energy to complete successfully. The desired crypto strength and method influence the time and energy required. "Crypto suite performance" is therefore defined in this document as "the shortest time to complete a crypto outcome at a given read distance in relation to the RF power available". This document provides guidelines in the evaluation of the measurement results. The test methods do not measure crypto capabilities which include crypto strength, suitability and robustness. They neither measure random generator performance nor deal with key management.
