Abstract
A smart card for use in connection with execution of a software program by a computer includes a microcontroller configured by a program stored in a smart card memory to verify information received from the computer during execution of the software program. The microcontroller is further configured to cause a signal to be stored in the smart card memory which is indicative of whether execution of the software program is certified as valid based on results of verifying the received information. Methods of using the smart card are also disclosed.
