Abstract
A system is provided that includes a wireless communication device (or end device), a vehicle having a central module, and a key provisioning server. The key provisioning server is communicatively coupled to the wireless communication device and the central module via wireless connections. The central module can establish a wireless connection with the wireless communication device to initiate a current communication session. When the wireless connection is established with the central module, the wireless communication device communicates a request message to request temporary security information (e.g., public key and/or a digital certificate). The key provisioning server can then provide, in response to the request message, the temporary security information to the wireless communication device and/or the central module. The temporary security information can then be used to encrypt communications between the wireless communication device and the central module.
