Abstract
An integrated circuit, having a security supervision system, comprising a plurality of functional circuit blocks interconnected to collectively performing data processing tasks, one or more communication adaptors, having: (i) a hardware interconnection to the functional circuit blocks, whereby the communication adaptor senses the state and/or activity of the functional circuit block; (ii) memory storing definitions of state and/or activity of functional circuit block and actions for each definition; and (iii) processing circuitry comparing the state and/or activity of the functional block with each definition, such that when state and/or activity of the functional block corresponding to a stored definition is detected, perform the corresponding action. The memory stores a definition of state and/or activity characteristic of insecure operation of the functional circuit block and a corresponding action to partially disabling the functional circuit block and/or (ii) causing a message to be transmitted to a destination off the integrated circuit.
