ABSTRACT:
In a method for using the shared library in a tamper resistant microprocessor, the execution code of the shared library is protected because the shared library itself is processed as a task which has a single identifier, and the instruction key for encrypting/decrypting the shared library is recorded at a location within the microprocessor corresponding to that identifier.
