Responsive to receiving of a connection request from a connecting device, a pre-authentication message is sent to the connecting device, the pre-authentication message including a challenge value. A vehicle hash result is computed using a hash function taking the challenge value and the unique identifier of the vehicle as inputs. A device hash result is received from the connecting device. Responsive to a match of the vehicle hash result and the device hash result, additional hardware of the vehicle is activated to perform a secondary authentication of the connecting device. Responsive to a mismatch, authentication of the connecting device is rejected without activation of the additional hardware, thereby avoiding key-off load from the additional hardware in instances where pre-authentication of the connecting device fails."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Unauthorized device resource drain prevention","description":"Detection and prevention of resource drain from unauthorized wireless device connections is provided.
