Method of configuring a network of tire monitoring devices

A method of configuring a network of tire pressure monitoring devices using an untrusted device, the method comprising:

• transmitting, by the untrusted device, respective configuration data to the tire pressure monitoring devices;
• receiving, by the untrusted device, respective inputs verifying that installed configuration data matches expected configuration data;
• and
• after receiving the respective inputs, transmitting, by the untrusted device, a command initializing generation of a cryptographic parameter by at least one of the tire pressure monitoring devices, and causing the cryptographic parameter to be exchanged with the other tire pressure monitoring devices such that secure future communication is established between the tire pressure monitoring devices,
• wherein the tire pressure monitoring devices are installed with the respective configuration data, and respective inputs verifying that the installed configuration data matches expected configuration data are received by the untrusted device, sequentially prior to transmission of the command, with configuration data transmitted to a tire pressure monitoring device and verified via the respective input prior to transmission of configuration data to a next sequential tire pressure monitoring device.
