Abstract: Disclosed is a method for detecting decoying of a traffic alert and collision avoidance system on-board an aircraft targeted by decoying. The method includes a phase of establishing a trusted network including the steps of dividing the space into a plurality of zones; and of selecting a verifier in each zone. The method further includes a phase of validation including the steps of generating an interrogation [sent] to each verifier; [a step of] reception of a response to each interrogation and verifying the response; and [a step of] analysis of all the responses so as to either validate or not validate the aircraft suspected of decoying, as false traffic.

Abstract: Disclosed is a method of detecting spoofing of a traffic alert and collision avoidance system, known as a TCAS, the TCAS having a Mode A, a Mode C and a Mode S for communicating with surrounding aircraft. The method includes: querying a suspected spoofing aircraft via Mode S of the TCAS and receiving a response to this query; deducing from the response at least some data, known as Mode S data, relating to the suspected spoofing aircraft; and validating Mode S data by querying the suspected spoofing aircraft via Mode A or Mode C of the TCAS.
