In accordance with one example embodiment, a public key of a mobile device is computed using a shared password as performed in accordance with authentication acts of a password-authenticated key exchange protocol, and transmitted to at least one other mobile device of the group. A public value is computed as a function of a mobile device private key and of a public key of at least one other mobile device of the device group, in accordance with a group key establishment protocol. The public values of the mobile devices of the device group are used to compute a shared encryption key."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and devices for computing a shared encryption key","description":"Embodiments described herein are generally directed to methods and devices in which computing devices, and mobile devices in particular, establish a shared encryption key for a device group comprising","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8510561","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.
