【摘要】 智能卡操作系统(Chip Operating System,简称COS)是智能卡在软件层面的核心技术。其研究和开发对智能卡技术的发展和普及有很大的促进作用。国内各卡商大多开发基于Native的COS(卡操作系统)平台,致力于智能卡芯片的研制,从硬件到软件的自主研发,形成了早期初级COS,移植性、通用性、维护性不好,多为单文件系统、单一应用、单通道,没有考虑多应用的实现,如多应用文件系统的实现、不同应用之间文件隔离、映射,多种PIN管理,多通道实现等。而JAVA卡平台通用性好,但对硬件资源要求非常高,且在实现多文件系统上是一个弱项。本文研制的UICC COS平台,在整体设计上通过合理的层次化结构,使上层的应用与底层硬件分离,便于平台的移植操作、维护性好;在文件系统设计上,采用了通用的文件系统,使平台具有良好的通用性;在安全性上做了充分的设计;在应用设计上依靠多通道、多文件系统以及多级PIN的相关技术实现了多应用。提出了二次开发的创新设计,保障了COS层以上应用的合作开发的安全可实现;此外,在掉电保护方面也做了设计和实现,保障了用户数据在使用过程中的安全性和可靠性。本文针对以上设计进行了可靠的脚本测试和实网验证工作,成功实现了UICC SIM和USIM功能,COS能够正常登网、通讯,并实现了USIM卡的批量商用。更多还原

【Abstract】 The kernel technique of software is the operating system(abbr. COS). The powerful COS can greatly promote the card system to be acceptable and feasible.The telecommunication smart card based on the 2G, especially in China, various cards business mostly has own COS platform based on Native; Specially the domestic enterprise, devote to the smart card chip development, independently researches and develops from the hardware to the software, polymorphism becomes the early time face SIM primary COS, but the portability ,the versatility and the maintenance are not good, most of them are single document systematic, sole application, single channel, they have not considered the multi-applications the realization,such as realization between multi-application filing system , different application document isolation, mapping, kinds of PIN management, multichannel realization and so on,the JAVA card platform is good onversatility , but it is extremely high to the hardware resources request,it is weak in realizes on the multiple file system. In view of in the above situation, this article has provided a kind of new COS platform design proposal. This article develops the platform of UICC COS, in the overall design through the reasonable hierarchical structure, causes the upper formation the application and the first floor hardware separates, it is advantageous for the platform the transplant operation, the maintenance is good; In the filing system design, it has used the general filing system which enables the platform to have the good versatility; It has made the full design in the security; In depended upon the multichannel, the multiple files using the design in systematic as well as the multistage PIN correlation techniques has realized the multi-applications; Proposed re-development’s innovative designs, safeguarded above the COS level the application cooperation development security to be possible to realize; In addition, it also did in the power failure protection aspect has designed and realizes, has safeguarded the user data in the use process security and the reliability. This article has carried on the reliable script test and the solid net confirmation work in view of the above design, the success has realized UICC SIM and the USIM function, COS can ascend the net and communicate normally.更多还原
