Due to economic development and improved quality of life, electricity demand has rapidly increased. However, the power grids in major cities have become outdated, leading to uneven power distribution and frequent power outages. SGs can adjust distribution strategies based on consumers\u2019 real-time electricity demands, which requires continuous transmission of consumer electricity data within the grid. If the privacy and security of these data cannot be ensured, consumers\u2019 habits will be exposed, and unnecessary waste may occur. In this article, we propose a key distribution process based on QKD, enabling entities within the SG to encrypt and authenticate each other\u2019s data, ensuring the security and privacy of communication channels and transmitted data.<\/jats:p>","DOI":"10.3390\/cryptography9020028","type":"journal-article","created":{"date-parts":[[2025,4,29]],"date-time":"2025-04-29T11:00:54Z","timestamp":1745924454000},"page":"28","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["A Quantum Key Distribution for Securing Smart Grids"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-3367-6317","authenticated-orcid":false,"given":"Iuon-Chang","family":"Lin","sequence":"first","affiliation":[{"name":"Department of Management Information Systems, National Chung Hsing University, Taichung 402, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ko-Yu","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Management Information Systems, National Chung Hsing University, Taichung 402, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nan-I","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Information Management, Lunghwa University of Science and Technology, Taoyuan 33306, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5502-8033","authenticated-orcid":false,"given":"Min-Shiang","family":"Hwang","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Information Engineering, Asia University, Taichung 41354, Taiwan"},{"name":"Department of Medical Research, China Medical University Hospital, China Medical University, Taichung 40402, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,29]]},"reference":[{"key":"ref_1","first-page":"901","article-title":"Research on Data Security and Privacy of Smart Grids","volume":"26","author":"Hwang","year":"2024","journal-title":"Int.
