Information based on the reusable identification handle and based on the reusable credential is transmitted to a potential peer. First information based on a reusable identification handle for the second user is received, and second information based on a reusable credential for the second user is received. A first comparison of a combination of the first information and the second information is performed with the matching reference to determine whether the second user's credentials match the first users matching reference. A second comparison of the first information with information published on a revocation list is performed to determine whether the second user's credentials have been revoked from usage. Based on the first comparison and the second comparison, a determination is made whether or not to verify the association of second user with the first user."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Revocation of credentials in secret handshake protocols","description":"According to a general aspect, a computer-implemented method for a first user to verify an association with a second user through a secret handshake protocol includes maintaining information about a r","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8533464","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
