IEC/TS 60870-5-7:2013（E）描述了作为IEC 60870-5-101和IEC 60870-5-104的扩展，用于实现安全认证的IEC/TS 62351-5的消息和数据格式。本基本标准的目的是允许任何IEC 60870-5-101/104应用协议数据单元（APDU）的接收器验证APDU是否由授权用户传输，以及APDU是否在传输过程中被修改。它提供的方法不仅可以验证发起APDU的设备，还可以验证个人用户（如果该功能由遥控系统的其余部分支持）。 本规范还将与IEC/TS 62351-3的定义以及IEC 60870-5-104配套标准一起使用。

IEC/TS 60870-5-7:2013(E) describes messages and data formats for implementing IEC/TS 62351-5 for secure authentication as an extension to IEC 60870-5-101 and IEC 60870-5-104. The purpose of this base standard is to permit the receiver of any IEC 60870-5-101/104 Application Protocol Data Unit (APDU) to verify that the APDU was transmitted by an authorized user and that the APDU was not modified in transit. It provides methods to authenticate not only the device which originated the APDU but also the individual human user if that capability is supported by the rest of the telecontrol system. This specification is also intended to be used, together with the definitions of IEC/TS 62351-3, in conjunction with the IEC 60870-5-104 companion standard.
