A METHOD OF CONFIGURING A NETWORK OF TIRE MONITORING DEVICES

Disclosed is a method of configuring a network of tire monitoring devices using an untrusted device. The method includes transmitting, by the untrusted device, first configuration data to a first tire monitoring device, and receiving, by the untrusted device, a first input verifying that the first configuration data has been loaded to the first tire monitoring device and matches expected first configuration data. The method includes transmitting, by the untrusted device, second configuration data to a second tire monitoring device, and receiving, by the untrusted device, a second input verifying that the second configuration data has been loaded to the second tire monitoring device and matches expected second configuration data. The method includes, after receipt of both the first input and the second input, transmitting, by the untrusted device, a command initialising generation of a cryptographic parameter by the first tire monitoring device, and causing the cryptographic parameter to be exchanged with the second tire monitoring device such that secure future communication is established between the first and second tire monitoring devices.
