摘要
PROBLEM TO BE SOLVED: To provide structure for securely performing a plurality of programs from unrelated vendors by including a context barrier for isolating execution of the programs in small area devices, such as smart cards.SOLUTION: A context barrier performs security checks for checking whether principal and an object are within the same context, or a requested action is authorized for the object to be operated. Each program or a set of programs is performed in a separate context. However, one context can access to all program modules without the constraint of the context barrier.
