Patent ID: 7937596

Claim:
A method for protecting embedded cryptographic processing circuits, software and data, contained within an electronic equipment, comprising: monitoring with a first processing device embedded in said electronic equipment a plurality of parameter values generated by a plurality of sensors provided in said electronic equipment in accordance with a base operating profile; evaluating with said first processing device each of said plurality of parameter values to determine if it falls within a respective one of a plurality of predetermined ranges of acceptable values in accordance with said base operating profile; automatically using a modified operating profile in said first processing device in place of said base operating profile to perform said monitoring or evaluating step if one or more of said parameter values is determined in said evaluating step not to be within said respective predetermined range; and selecting said modified operating profile to include one or more defined variables which are different as compared to defined variables of said base operating profile, said defined variables selected from a group consisting of said plurality of predetermined ranges of acceptable values, the parameter values that are evaluated, and a rate at which said parameter values are evaluated.
