Abstract: With the development of chip technology and the business expansion among operators,mobile cell smart card will be the direction of the multi-application platform.This article focuses on the research and design which contains file systems,security mechanisms,and pairs of channel communication management based on the multi-application request.Finally,one kind of multi-application Chip Operating System(COS) structure is designed and a simple experiment is implemented based on RF_SIM cards,the design has higher stable and safety and has some value for other researchers to design multi-application COS.

Key words: chip operating system, security mechanism, dual channel

摘要: 随着芯片技术的发展以及运营商之间的业务扩展,手机智能卡将会向多应用平台方向发展。就是在多应用要求下,重点对文件系统、安全机制和双通道通信管理进行研究与设计。最后基于RF_SIM卡设计了一种多应用COS(智能卡操作系统)结构和实现了一个简单原型,具有较高的稳定性和安全性,对其他研究人员设计多应用COS有一定的借签价值。
