The design + is presented as an extension of a privacy-friendly payment protocol with a + zero-knowledge scheme that cryprographically augments coins for this purpose. + Our scheme enables buyers to prove to be of sufficient age for a particular + transaction without disclosing it. Our modification preserves the privacy and + security properties of the payment system such as the anonymity of minors as + buyers as well as unlinkability of transactions. We show how our scheme can be + instantiated with ECDSA as well with a variant of EdDSA, respectively, and how + it can be integrated with the GNU Taler payment system. We provide formal + proofs and implementation of our proposal. Key performance measurements for + various CPU architectures and implementations are presented. +</p> +<h2>Download links</h2> +<ul> + <li><a href="/papers/esorics2022-age-restriction.pdf">PDF (English)</a></li> +</ul> + +{% endblock body_content %} @@ -28,6 +28,9 @@ langs_full: tr: Türkçe meetingnotes: newsposts: + - page: 2022-09.html + date: 2022-08-09 + title: "Zero-Knowledge Age Restriction for GNU Taler" - page: 2022-08.html date: 2022-06-26 title: "Datenschutzfreundliches digitales Bezahlen" @@ -39,13 +42,13 @@ newsposts: title: "GNU Taler Scalability" - page: 2022-05.html date: 2022-05-25 - title: "Who comes after us?
