Abstract

The invention relates to a characteristic value processing method for hardware Trojan detection without a clean circuit board for comparison. A system is established for processing characteristic values acquired for hardware Trojan detection, and accordingly abnormal data are detected without the clean circuit board for comparison. Moreover, the method provides two selectable detection schemes which are a model-free detection scheme and a model detection scheme respectively, wherein the model-free detection scheme includes the steps of circularly calling various parameters (including distance functions and a classification method) by the aid of an unsupervised clustering method to obtain a clustering-based strategy highest in evaluation function, and then classifying, the model-free detection scheme is high in speed, and the precision already meet primary demand; and the model detection scheme uses a unsupervised neural network algorithm which is low in speed but high in precision, serves as an selection of the detection schemes but is not necessary, and is applicable to situations high in requirement on precision.

Description

technical field

[0001] The invention relates to a method for processing characteristic values ​​of Trojan horse detection, in particular to a method for processing characteristic values ​​of hardware Trojan horse detection. Background technique

[0002] Currently, there are four hardware Trojan detection methods: physical inspection, functional testing, built-in self-test and bypass analysis techniques. These four schemes, when detecting hardware Trojans, all need to use a golden board, that is, a clean circuit board as a contrast, so that circuits containing hardware Trojans can be detected. But this method makes the cost need to be greatly improved, because obtaining a clean circuit board requires a lot of manpower and material resources. Contents of the invention

[0003] The present invention mainly solves the technical problems existing in the prior art; it provides a hardware Trojan detection eigenvalue processing method that can detect whether the circuit board is ...
