The first instance of the function results in the client obtaining a root secret key and the MAS obtaining a corresponding root public key. The method includes authenticating the client to the MAS by performing a first portion of a second instance of the distributed threshold oblivious pseudo-random function. The second instance of the function results in the client obtaining the root secret key. Information stored by the client, the first secret key, and a second secret key generated by a support authentication server are inputs to at least one of the first and second instances of the distributed threshold oblivious pseudo-random function."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Password-authenticated public key establishment","description":"A method for cryptographic key provisioning includes, via a main authentication server (MAS), generating a first secret key and registering a client by performing a first portion of a first instance o","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11296875","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.
