摘要:
This invention concerns a method to control the access to objects (5) stored in a memory space of a computer system by a subject (3) stored in a program space of said system. The subject wants to perform an operation on said objects (5). The method according to the invention controls the access to said objects (5) via a dynamic attribute (8) linked to said subject (3) whose value is updated according to the present and previous status(es) of the subject. This invention also concerns the access control device implementing the method described above.
