The key fob is capable of transmitting only (not receiving) and is paired with a control unit in a vehicle or with any other control device. Use of the key fob and control unit IDs prevents unauthorized pairing and access to the operation key (OpKey) that is later used for communications between the devices. Elliptical curve cryptography (ECC) is used for strong security and efficient implementation. In the pairing process, device IDs are used for entity authentication and public key cryptography is used for easy key management. Symmetric encryption is used for fast normal operation and to accommodate key fob addition or revocation after key fob loss."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"One-way key fob and vehicle pairing","description":"Key fob and vehicle control unit identifiers (IDs) are used for entity authentication or trust transfer to achieve a secured initial pairing.
