IoT networks generally face security problems of privacy leakage and message denial. To protect the privacy of IoT data and users, this paper first introduces a controlled verification model for IoT networks and then proposes an identity-based undeniable signature (ID-US) scheme. This controlled verification model establishes a secure IoT data-sharing channel with blockchain technology, which reduces data tampering and inconsistency. This ID-US scheme is constructed with lattice cryptography, which can provide strong resistance to quantum attacks. Meanwhile, the undeniable and identity mechanisms ensure that the signed message cannot be denied. Next, the security proof in the random oracle model shows that this ID-US can achieve soundness and unforgeability. The Scyther test results show that there are no attacks by verifying 11 points of attacks from the perspectives of the KGC, signer, and verifier. Moreover, the efficiency analysis and performance analysis of the key size, time consumption, energy consumption, and transaction latency have been performed, and the results show that the ID-US scheme is more efficient than similar schemes in the recently published literature, and the controlled verification model can protect IoT data privacy and support secure IoT data sharing with the undeniable property.<\/jats:p>","DOI":"10.3390\/s26196205","type":"journal-article","created":{"date-parts":[[2026,9,30]],"date-time":"2026-09-30T13:01:19Z","timestamp":1790773279000},"page":"6205","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Privacy-Preserving Identity-Based Undeniable Signatures from Lattices with Controlled Verifiability for IoT Networks"],"prefix":"10.3390","volume":"26","author":[{"given":"Jing","family":"Cheng","sequence":"first","affiliation":[{"name":"Engineering Training Center, Zhengzhou University of Light Industry, Zhengzhou 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"}]},{"given":"Rui","family":"Lu","sequence":"additional","affiliation":[{"name":"College of Software Engineering, Zhengzhou University of Light Industry, Zhengzhou 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1455-2714","authenticated-orcid":false,"given":"Chaoyang","family":"Li","sequence":"additional","affiliation":[{"name":"College of Software Engineering, Zhengzhou University of Light Industry, Zhengzhou 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"}]},{"given":"Haseeb","family":"Ahmad","sequence":"additional","affiliation":[{"name":"Department of Computer Science, National Textile University, Faisalabad 37610, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"supervision","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]},{"given":"Shujun","family":"Liang","sequence":"additional","affiliation":[{"name":"College of Software Engineering, Zhengzhou University of Light Industry, Zhengzhou 450001, China"},{"name":"Research Institute of Industrial Technology, Zhengzhou University of Light Industry, Zhengzhou 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"4163","DOI":"10.1016\/j.jksuci.2021.03.006","article-title":"A review of IoT network management: Current status and perspectives","volume":"7","author":"Aboubakar","year":"2022","journal-title":"J.
