摘　　要：首先介绍了一种实现多COS功能的新型智能卡概念UCard及其体系结构与基本特征.接着在分析了发卡商对UCard安全性的要求后,给出了UCard安全性的三个目标:COS安全地分配到独立的存储空间中;运行的COS不能访问到其他COS数据;运行结束的COS的信息不能被以后的COS获取到.然后围绕这三个目标详细论述了UCard在发卡时、COS运行时及运行结束后的安全性问题、原理及可能的实现.UCard is a new card to realize the function of multi-COS. Its architecture and basic characteristics were described. By analyzing issuers′ requirements of UCard security, three goals of UCards security were presented: a. each COS should be assigned to an independent memory space safely; b. the running COS has no access to the date of any other COS; c. the data of preceding-running COS can not be obtained by subsequent COS. When UCard is issued or one COS is running or ended, their security problems, theories and potential realization were also dealt with.
