【摘要】：智能卡是电子商务中信息脱离宿主机保存的轻便型载体,在载体中信息的处理脱离了网络的开放环境,它在电子商务市场等方面的应用逐渐普及。智能卡操作系统(Chip Operation System, COS)是外界信息与智能卡内部交流的中间件,它只为上层应用提供功能接口,没有向用户独立展示业务的能力。本文的目的是实现一个能够作为电子商务市场应用平台的新型智能卡操作系统。本文根据现有的状况对系统进行了详细的需求分析,主要是功能点的提取和模块划分。在此基础上,从系统的硬件架构和软件架构对系统进行了概要分析,硬件平台详细说明了支持该系统的芯片存储器组成结构,然后针对软件系统的各个功能模块进行了详细设计,对其中重要模块的功能做了流程说明和要点实现,最后对项目进行了测试并给出了相关的展示成果。智能卡操作系统开发使用了嵌入式开发技术,内部命令按照ISO7816的APDU (Application Protocol Data Unit,数据传输单元)组织。本人在整个项目中参与了需求分析、系统设计、设计运行到推广应用的全过程,其中主要的工作包括通信组件的通信模式、命令解释组件、文件系统自定义数据文件、安全管理组件、PATCH补丁机制和数据备份与恢复的分析、设计、实现和测试等工作。目前已有多个应用均采用该COS作为后端信息处理平台并得到了不错的反响。系统性能稳定、业务支持力强,减少了拓展新业务的周期,降低了开发组同时的工作压力,减少了研发延迟的现象,得到了用户积极的反馈。
[Abstract]:Smart card is a portable carrier of electronic commerce, in which the information is stored away from the host, and the processing of information in the carrier is divorced from the open environment of the network. The smart card operating system chip Operation system (COSs) is the middleware for the internal communication between the external information and the smart card, and it only provides the functional interface for the upper application. The purpose of this paper is to implement a new smart card operating system which can be used as the application platform of e-commerce market. On the basis of this, the hardware and software architecture of the system are analyzed briefly, and the structure of the chip memory supporting the system is explained in detail by the hardware platform. Then, the function modules of the software system are designed in detail, and the functions of the important modules are described and implemented. Finally, the project is tested and the related results are presented. The embedded development technology is used in the development of the smart card operating system. The internal command is organized according to ISO7816's APDU Application Protocol Data Unit. I participated in the whole process of requirement analysis, system design, design and application, including the communication mode of communication components. Command interpretation component, file system custom data file, security management component PATCH patch mechanism and data backup and recovery analysis, design, At present, many applications have adopted the COS as the back-end information processing platform and got a good response. The system has stable performance, strong business support, and reduces the period of expanding new business. It reduces the working pressure of the development team at the same time, reduces the phenomenon of R & D delay, and gets positive feedback from the users.
