ABSTRACT:
This invention relates in general to object-oriented encapsulated enforcement mechanisms. In particular, a hardware independent object encapsulation enforcement mechanism is disclosed herein. The object encapsulation enforcement mechanism of the present invention uses encryption technology to ensure that data controlled by an object is accessed solely through use of the object's method programs. When an object is instantiated, the virtual address used to refer to the object is encrypted before it is returned to the instantiating application program. When access to a previously instantiated object is requested, the object encapsulation enforcement mechanism decrypts the presented object address and passes the address to the identified method program, thereby ensuring that only object method programs have access to data controlled by the object.
