Abstract
A key fob device, in one embodiment, includes a transceiver that receives and sends signals, a memory that stores a public key and a certificate of authenticity associated with the key fob device, and a processor coupled to the transceiver and memory. The processor is configured to execute instructions causing the key fob device to transmit the public key and the certificate of authenticity, execute a public key agreement protocol to generate a common secret encryption key, and receive an operation key encrypted with the common secret encryption key.
