The circuitry also performs with a verifier, an interactive protocol for proving knowledge of (L−1) secret keys si that satisfy yi=F(si). The circuitry receives L challenges from the verifier, arbitrarily selects (L−1) challenges from the L challenges received. The circuitry also generates, by using the secret keys si, (L−1) responses respectively for the (L−1) challenges selected, and transmits the (L−1) responses generated."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Authentication device, authentication method, and program","description":"An authentication device includes circuitry that holds L (L≧2) secret keys si (i=1 to L) and L public keys yi that satisfy yi=F(si) with respect to a set F of multivariate polynomials of n-th order (n","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9602285","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.
