Techniques for implementing security on a small footprint device using a context barrier

一种小型注脚设备如智能卡，通过包含一个将多个程序的执行隔开的文本屏障，其能够安全地运行来自不相关的供货商的多个程序。该文本屏障进行安全检测以确定主体和对象是否在同一名字空间或存储空间中，或者用来确定请求的操作是否授权给准备被操作的对象。 A small footprint device, such as a smart card, can securely run multiple programs from unrelated vendors by the inclusion of a context barrier isolating the execution of the progra...

Summary:一种小型注脚设备如智能卡，通过包含一个将多个程序的执行隔开的文本屏障，其能够安全地运行来自不相关的供货商的多个程序。该文本屏障进行安全检测以确定主体和对象是否在同一名字空间或存储空间中，或者用来确定请求的操作是否授权给准备被操作的对象。 A small footprint device, such as a smart card, can securely run multiple programs from unrelated vendors by the inclusion of a context barrier isolating the execution of the programs. The context barrier performs security checks to see that principal and object are within the same namespace or memory space or to see that a requested action is authorized for an object to be operated upon.
