Method for weakening process deviation influence in hardware Trojan detection

Abstract

The invention discloses a method for weakening process deviation influence in hardware Trojan detection. The method comprises the following steps of inserting m groups of circuit structures used for parameter correction in the link of designing an integrated circuit chip; delivering a design to a factory to implement tape-out production; testing the circuit structures used for the parameter correction by using a probe station and other instrument equipment, and implementing recording processing on collected typical characteristic parameters before the final packaging test loop; correcting the typical characteristic parameters of an emulator according to processing results, and implementing re-emulation on characteristic circuit performance parameters to establish a new base version for the chip; finally, implementing differencing between the actually measured data of the characteristic circuit performance parameters used for the hardware Trojan detection and the new parent, and comparing a difference value with a threshold value so as to judge whether hardware Trojan is planted into the integrated circuit chip or not. According to the method, when the two base versions are compared, the new base version after being subjected to parameter correction can reflect current chip characteristics much better, so that the influence of process deviation on the hardware Trojan detection is effectively weakened.

Description

technical field [0001] The invention effectively weakens the influence of process deviation on hardware Trojan horse detection and improves detection accuracy by inserting a circuit structure for parameter correction in the integrated circuit design stage. Background technique [0002] With the separation of integrated circuit design and manufacturing, and the use of a large number of IP cores, there are more and more risks in the outsourced manufacturing of integrated circuit chips, making integrated circuit chips vulnerable to attacks and implanted by others as hardware Trojan horses. Hardware Trojans refer to malicious tampering of original circuits during the design or manufacture of integrated circuits. Hardware Trojans pose a great threat to the security of integrated circuits, and it is urgent to carry out the detection of hardware Trojans. The side channel analysis method is currently a research hotspot in the field of hardware Trojan horse detection [1]. This metho...
