Users can be authenticated by pieces of attributes rather than the whole identity. Attribute-based anonymous credential systems enable a user to prove possession of a given set of attributes to a verifier, without revealing information about other attributes. However, the challenge lies in how to securely prove the possession of attributes. In our paper, we propose a decentralized zero-knowledge protocol for attribute verification. There are three attribute verification modes, namely\n                    <jats:italic>1-out-of-n<\/jats:italic>\n                    ,\n                    <jats:italic>n-out-of-n<\/jats:italic>\n                    , and the\n                    <jats:italic>Combined Verification Mode<\/jats:italic>\n                    . The first two modes represent the \"OR\" and \"AND\" gates, while the Combined Verification Mode supports an OR of non-empty groups of AND attributes. We prove the security properties of the protocol in the security analysis. Meanwhile, we also outline some of the use-cases and applications of the proposed protocol, such as Internet of Things(IoT), federated learning and data validation.\n                  <\/jats:p>","DOI":"10.1007\/s10586-026-06646-0","type":"journal-article","created":{"date-parts":[[2026,10,22]],"date-time":"2026-10-22T18:32:01Z","timestamp":1792693921000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["VeriPriv: a privacy preserving attribute verification protocol for decentralized authentication"],"prefix":"10.1007","volume":"29","author":[{"given":"Mohammed","family":"Alshawki","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuping","family":"Yan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fatemeh","family":"Stodt","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christoph","family":"Reich","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Ligeti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,10,22]]},"reference":[{"key":"6646_CR1","doi-asserted-by":"crossref","unstructured":"Mirzamohammadi, S., Chen, J.A., Sani, A.A., Mehrotra, S., Tsudik, G.: Ditio: Trustworthy auditing of sensor activities in mobile & iot devices.
