ABSTRACT:
Disclosed is a method and apparatus to increase the security of an integrated circuit, the integrated circuit including at least one microprocessor, one or more security sensors to detect abnormal conditions of operation, and registers accessible by the microprocessor which store a state of a respective sensor. The microprocessor reads the contents of a register only at the end of a random period where the duration of the random period is determined by a number generated by a random number generator.
