Abstract:
1. A method for unsolicited identity authentication of an ADS-B system comprising the steps of: (a) generating an authentication secure code by inputting said ADS-B transmitter system's specific data, ID and secret-key in secure processing in said ADS-B transmitter system; (b) transmitting an ADS-B message comprising said ADS-B transmitter system's specific data, ID and secure code from said ADS-B transmitter system; (c) receiving at least one of said ADS-B messages transmitted from said at least one ADS-B transmitter system at an authentication monitoring system; (d) determining said at least one ADS-B transmitter system's secret-key independently at said authentication monitoring system; (e) generating an authentication secure code by inputting said ADS-B transmitter system's specific data, ID and said ADS-B transmitter system's secret-key in secure processing in said authentication monitoring system; (f) comparing said authentication monitoring system-generated secure code and said ADS-B transmitter-generated secure code using comparison processing for each of said at least one ADS-B transmitter system at said authentication monitoring system; and (g) authenticating said ADS-B transmitter system's identity where the output of said comparison processing is said authentication monitoring system-generated secure code and said ADS-B transmitter-generated secure code are the same,
