Abstract: A method of configuring a network of tire monitoring devices using an untrusted device is provided. An untrusted device transmits first configuration data to a first tire monitoring device, and then receives 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 untrusted device transmits second configuration data to a second tire monitoring device, and receives 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 untrusted device transmits a command initializing generation of a cryptographic parameter by the first tire monitoring device, and causes 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.

Abstract: A method of performing a configuration procedure for first and second tire pressure monitoring devices. The method includes loading the first tire pressure monitoring device with first configuration data, and subsequently transmitting, from the first tire pressure monitoring device, a first configuration data signal which encodes the first configuration data. The method includes subsequently loading the second tire pressure monitoring device with second configuration data, and subsequently ending the configuration procedure without transmitting a second configuration data signal which encodes the second configuration data.

Abstract: A method of communicating configuration data of a tire pressure monitoring device configured to be affixed to a wheel in use. The method includes, at the tire pressure monitoring device, receiving a request to confirm configuration data, and responsive to receipt of the request to confirm configuration data, transmitting a configuration data signal which encodes the configuration data. The configuration data signal is configured to be received and understood by a human.

Abstract: A communication system for an aircraft comprises a communication interface with the outside of the aircraft and an avionics domain of which the security level is the highest of the communication system. It also comprises a communication domain to which is connected the communication interface and of which the security level is lower than the security level of the avionics domain. A barrier of a first type is arranged to filter the information coming from the communication interface so as to allow the information to pass into the communication domain only if the information corresponds to an authenticated communication. A barrier of a second type is arranged to filter information transmitted from the communication domain to the avionics domain, carrying out at least a syntactic filtering of the information.
