标准范围

IEC 62055-42:2022规定了在不使用符合IEC 62055-41标准的系统以及特定项目或国家要求需要不同安全机制的市场中智能预付费功能的令牌生成机制和令牌结构。本文档指定了令牌结构、认证和防重放机制、令牌操作模型和协议。本文档由STS协会密钥管理服务和IEC 62056中DLMS/COSEM安全模型中使用的密钥管理机制提供信息？6？2.参考用于支付计量系统的国际STS令牌标准(IEC 62055-41、IEC 62055-51和IEC 62055-52)，并且已经在适当的情况下根据十进制域中的令牌载体范围考虑了互通。IEC 62055-41令牌和本文档中描述的令牌不可互操作，但是它们的域被设计为互斥，以确保这两种令牌不会相互干扰。计量应用程序处理和功能、HAN接口命令和属性、WAN接口命令和属性超出了本文档的范围；然而，在这方面参考了其他标准。从仪表中审核和检索与资费、仪表读数、配置文件数据和其他法定计量信息相关的数据的机制不在本文件的范围内；然而，这被定义为任何整体计量解决方案的一部分。用于从仪表检索数据的这种接口可以使用合适的协议来定义，例如IEC 62056系列中定义的DLMS/COSEM。

IEC 62055-42:2022, specifies a token generation mechanism and token structure for smart prepayment functionality in markets where IEC 62055-41 compliant systems are not used, and where a different security mechanism is required by project-specific or national requirements. This document specifies token structure, authentication and an anti-replay mechanism, token operating model, and protocol.
This document is informed by the STS Association key management services, and by the key management mechanisms used within the DLMS/COSEM security model within IEC 62056？6？2. Reference is made to the international STS token standards (IEC 62055-41, IEC 62055-51 and IEC 62055-52) for payment metering systems, and interworking has been considered where appropriate in terms of token carrier ranges in the decimal domain. IEC 62055-41 tokens and those described in this document are not interoperable, however their domains are designed to be mutually exclusive to ensure the two kinds of tokens do not interfere with each other.
Metering application processing and functionality, HAN interface commands and attributes, WAN interface commands and attributes are outside the scope of this document; however, reference is made to other standards in this regard.
The mechanism for auditing and retrieving data from the meter relating to tariffication, meter readings, profile data and other legal metrology information is outside the scope of this document; however, this is defined as part of any overall metering solution. Such interfaces for retrieving data from a meter may be defined using suitable protocols such as DLMS/COSEM as defined in the IEC 62056 series.
