BS ISO/IEC 18328-3:2016规定了通过支持APDU的物理接口与外部世界通信的卡IC中支持必要安全功能的应用程序的逻辑接口。此应用程序支持使用电子设备。这涉及到处理数据和处理附加设备本身所需的命令、数据结构和安全机制的设计。附加设备的处理始终由IC卡控制。外部输入或输出应由现有接口管理。 本文档不涉及卡和接口技术的物理特性，而只涉及逻辑方面。COS或应用程序控制未限制的其他设备的数据管理不在本文件范围内。警告、字体、颜色等管理数据“信任评估”的编码要求定义在本文件范围内。COS或设备驱动程序（如有）使用的逻辑内部接口功能的描述也是本文档的一部分。 由于相关技术可能会迅速发展或采用，本文档定义了支持扩展和改编的命令和结构。交叉引用:ISO/IEC 7816-4ISO/IEC 7816-6ISO/IEC 8825-1ISO/IEC 8859-1购买时可用的所有现行修订版均包含在本文件的购买中。

BS ISO/IEC 18328-3:2016 specifies the logical interface of an application supporting the necessary security features in a card-IC which communicates with the external world by a physical interface supporting APDUs. This application supports the usage of electronic devices.This involves the design of commands, data structures and security mechanisms which are required to handle the data and handling the additional devices itself. The handling of the additional devices is always controlled by the card-IC. External inputs or outputs shall be managed by the existing interfaces. This document deals not with physical characteristics of the card and interface technology, but only with the logical aspects. Management of data for additional devices that is not subdued by the COS or application control is out of the scope of this document.Definitions of coding requirement for "trust assessment" of the managed data like warning, font, colour etc. is in the scope of this document. A description of the logical internal interface functionality used by the COS or by device drivers, if any, is also part of this document.Due to the fact that relevant technologies may evolve or be adopted very fast, this document defines commands and structures supporting extensions and adaptations.Cross References:ISO/IEC 7816-4ISO/IEC 7816-6ISO/IEC 8825-1ISO/IEC 8859-1All current amendments available at time of purchase are included with the purchase of this document.
