As electronic systems become increasingly complex and globally distributed, the risk of malicious modifications or unauthorized alterations to hardware components continues to grow.<\/jats:p>\n                  <jats:p>In this survey, we provide a comprehensive exploration of detection and mitigation strategies for invasive hardware tampering across multiple levels of the hardware stack. We consider threats at various granularities\u2013from individual on-board integrated circuits (ICs), to Printed Circuit Board Assemblies (PCBAs), and up to complete end-user devices. Our focus centers on three primary categories of invasive tampering: hardware Trojans, counterfeit components, and physical manipulations. A key emphasis of this survey is on hardware security techniques that leverage alterations in electrical characteristics induced by tampering. These include changes in power delivery network (PDN), signal trace, and other low-level electrical pathways. Such variations often serve as sensitive indicators of physical intrusions or modifications and are particularly useful for monitoring hardware integrity throughout its lifecycle\u2013from manufacturing and deployment to maintenance and eventual decommissioning. We examine both golden-reference-based and golden-free detection approaches, highlighting their operational principles, design tradeoffs, and applicability in different threat scenarios. Furthermore, we survey evaluation methodologies and metrics used to assess the effectiveness, scalability, and robustness of these techniques.<\/jats:p>\n                  <jats:p>This article aims at providing a unified and up-to-date overview of detection research framework based on electrical characteristic variation, offering critical insights for researchers and practitioners working to safeguard hardware systems against invasive tampering and supply chain threats.<\/jats:p>","DOI":"10.1145\/3779441","type":"journal-article","created":{"date-parts":[[2025,12,10]],"date-time":"2025-12-10T11:34:17Z","timestamp":1765366457000},"page":"1-31","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["From ICs to Device: A Survey on Hardware Tampering Detection via Power Delivery Network and Signal Trace"],"prefix":"10.1145","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-5636-9520","authenticated-orcid":false,"given":"Minqing","family":"Sun","sequence":"first","affiliation":[{"name":"Shanghai Jiao Tong University","place":["Shanghai, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-3871-041X","authenticated-orcid":false,"given":"Lanqi","family":"Ding","sequence":"additional","affiliation":[{"name":"Shanghai Jiao Tong University","place":["Shanghai, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0099-1911","authenticated-orcid":false,"given":"Huifeng","family":"Zhu","sequence":"additional","affiliation":[{"name":"Washington University in St Louis","place":["St. Louis, United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8791-0597","authenticated-orcid":false,"given":"Yier","family":"Jin","sequence":"additional","affiliation":[{"name":"University of Science and Technology of China","place":["Hefei, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0083-5281","authenticated-orcid":false,"given":"An","family":"Zou","sequence":"additional","affiliation":[{"name":"Shanghai Jiao Tong University","place":["Shanghai, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2026,1,28]]},"reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10207-023-00801-z"},{"key":"e_1_3_1_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00521-021-06115-2"},{"key":"e_1_3_1_4_2","series-title":"Lecture Notes in Computer Science","doi-asserted-by":"crossref","first-page":"29","DOI":"10.1007\/3-540-36400-5_4","volume-title":"Proceedings of the Cryptographic Hardware and Embedded Systems.","volume":"2523","author":"Agrawal D.","year":"2003","unstructured":"D.
