电子收费.专用短程通信的应用接口定义

[中文适用范围]： 本文件规定了使用专用短程通信（DSRC）的电子收费（EFC）系统中的应用程序接口。 EFC 应用接口是 EFC 应用处理接口到 DSRC 应用层，如图 1 所示。本文档包括以下内容规范： — EFC 属性（即 EFC 应用信息），也可用于其他应用程序和/或接口； — EFC属性和（硬件）组件（如集成电路卡）的寻址程序； — EFCap应用功能，即通过相关服务的定义对动作进行进一步限定，分配相关的ActionType值，以及动作参数的内容和含义； — EFC 交易模型，定义了任何 EFC 交易的共同要素和步骤； — 接口的行为，以确保 EFC-DSRC 应用程序接口级别的互操作性。图 1 — EFC 应用程序接口 这是一个接口标准，遵循开放系统互连 (OSI) 理念（参见 ISO/IEC 7498-1），因此它主要不关注接口两侧要实现的实现选择。本文档提供特定于安全的功能作为占位符（数据和功能），以实现安全的 EFC 交易。然而，安全策略的规范（包括特定的安全算法和密钥管理）仍然由 EFC 运营商自行决定和控制，因此超出了本文档的范围。 [外文原描述]： This document specifies the application interface in the context of electronic fee collection (EFC) systems using dedicated short-range communication (DSRC). The EFC application interface is the EFC application process interface to the DSRC application layer, as can be seen in Figure 1 . This document comprises specifications of: — EFC attributes (i.e. EFC application information) that can also be used for other applications and/or interfaces; — the addressing procedures of EFC attributes and (hardware) components (e.g. integrated circuit(s) card); — EFC application functions, i.e. further qualification of actions by definitions of the concerned services, assignment of associated ActionType values, and content and meaning of action parameters; — the EFC transaction model, which defines the common elements and steps of any EFC transaction; — the behaviour of the interface so as to ensure interoperability on an EFC-DSRC application interface level. This is an interface standard, adhering to the open systems interconnection (OSI) philosophy (see ISO/IEC 7498 - 1 ), and it is as such not primarily concerned with the implementation choices to be realized at either side of the interface. This document provides security-specific functionality as place holders (data and functions) to enable the implementation of secure EFC transactions. Yet the specification of the security policy (including specific security algorithms and key management) remains at the discretion and under the control of the EFC operator, and hence is outside the scope of this document.
