The NICS Lab group participated with Nokia Spain (previously Alcatel Lucent España) in the development of a test bench for vehicular communications based on Bluetooth, to be used to validate different security protocols. This collaboration began in 2012 as part of a project of the INNPACTO progamme, financed by the Ministry of Economy and Competivity with the DEPHISIT project. In this first project, security aspects focused on ensuring the vehicle’s internal communications. Later, in 2016, this collaboration continued with financing from CDTI [Centre for Industrial Technological Development]. In this case work focused on vehicle to infrastructure communication, and in particular on the development of a secure connected traffic light that could adapt its operating cycle depending on the passage of emergency vehicles, and that would also inform regarding the time left until the change of status to enable vehicles to adapt their speed in accordance and reduce the emissions produced by excess consumption in cities due to traffic congestion.
