摘　　要：简要介绍智能卡操作系统的基本概念及操作系统的文件结构;以接触式51智能卡为例,说明补丁在智能卡操作系统中的应用,并针对当前补丁下载方法的不足,提出一种操作系统的补丁管理机制,以实现发卡后可以实时更新卡片应用程序,或者修改卡片操作系统中存在的问题.文中给出具体的实例,并进行分析,给出实现方法和步骤,同时验证了此补丁下载方法的可行性.本文中提出的补丁管理机制,较一般的补丁下载具有很强的灵活性,可以一次下载多个补丁,并方便对多个补丁进行管理.This paper briefly introduces the basic concept of the smart card operating system, and the file structure. Taking the contact smart card for example, the paper introduces application of patch in smart card operating system. And for the problems of the traditional method to download patch, it designs a patch management mechanism of the operating system in order to achieve the real-time update of the application process of the card after it is issued, to meet the needs of new users or modify the BUG existing in the COS. The paper gives specific examples and analysis, and the methods and steps of downloading patchs, tben verify the feasibility of this method. This patch management mechanism is flexible than other common patch mechanism, and more than one patch can be downloaded at the same time, also it is Convenient for management of a number of patchs.
