For example, various vehicle-to-everything (V2X) transmissions may be unencrypted, and a vehicle may be expected to periodically change one or more identifiers it uses for various communication services. Privacy may be enhanced, for example, via encryption key roll-over, as well as roll-over of one or more other identifiers associated with a UE that may potentially be used by an observer to track the UE. The UE may transmit a message that includes an updated lower layer identifier (e.g., a layer-2 (L2) identifier) to another UE in a V2X unicast communications link, which may trigger a change in identifiers of a set of identifiers and an updated security context. All or a portion of the message may be encrypted."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Roll-over of identifiers and keys for unicast vehicle to vehicle communication links","description":"Methods, systems, and devices for wireless communications are described that improve privacy in wireless communications, such as communications by a user equipment (UE), which may in some cases be a v","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11265707","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.
