Abstract
A method for secure wireless communication executed by at least one processor of a device. A registration certificate is transmitted to the device by a host, the registration certificate including a Long Term Device Key (LTDK) and being generated by a registration server in response to the registration of the host as authorized to connect to the device. In response to receiving a request for securing a Bluetooth connection between the device and the host, the device transmits the LTDK to the host. The device receives, from the host, a connection certificate including connection data for establishing the connection between the host and the device. The connection certificate is signed by a private Long Term Host Key (LTHK) of the host, where the LTHK of the host and the LTDK of the device form a cryptographic Long Term Key pair. The device validates the connection certificate using the LTDK of the device to determine whether the host is authorized to connect to the device. If the host is authorized, then the device establishes a shared secret with the host enabling the encryption of data transmitted over a wireless channel between the device and the host.
