Abstract : Computer system security has related to security of software or the information processed. The underlying hardware used for information processing has considered to as trusted. The emerging attacks from Hardware Trojans (HTs) violate this root of trust. The attacks are in the form of malicious modification of electronic hardware at different stages; possess major security concern in the electronic industries. An adversary can mount HT in a net of the circuit, which has low transition probability. In this paper, the improvement of the transition probability by using test points and weighted random patterns is proposed. The improvement in the transition probability can accelerate the detection of HTs. This paper implements weighted random number generator techniques to improve the transition probability. This technique is evaluated on ISCAS 85’ benchmark circuit using PYTHON and SYNOPSYS TETRAMAX tool. © 2019, ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering.
