Abstract
Systems and method are disclosed for performing profiling on a secure device. In embodiments, a plurality of counters are established. Each counter may be related to a different type of message. When the secure device receives and/or processes a message, it determines the type of message and adjusts a counter related to the determined message type. A ratio may be computed between the different counters. When the ratio deviates from a threshold, the secure device may be performing illegitimate operations, and one or more countermeasures are deployed against the illegitimate secure device.
