Abstract
Method and apparatus for performing access censorship in a data processing system (10). In one embodiment, a digital data processing system (10) has a sub-system (34) that can be protected against intrusions, yet is still accessible and/or alterable under certain defined conditions. In a non-volatile storage portion (48) of the data processing system (10), censorship information is stored to enable an access control mechanism. Access control information (42) to selectively disable the access control mechanism is programmably generated. Additional access control information (44) can be employed to reprogram a data processing system (10) containing access protected data in a secure mode.
