A method and apparatus for protecting computer software from unauthorized execution or duplication using a hardware key is disclosed. The apparatus comprises a means for communicating with the computer to receive command messages from the computer in the hardware key and to provide response messages to the computer, a memory for storing data for translating command messages into response messages enabling software execution, and a processor coupled to the interface port for translating command messages into response messages using the data stored in the memory. The processor further comprises a memory manager, for logically segmenting the memory storing the data into at least one protected segment, and for controlling access to the protected segment.
