The smart ocean is an influencer concept incorporating digitalized associated ocean and seaboard cities. The construction of an omni-bearing smart ocean requires urban resilience, and the application of smart means can greatly improve a city's emergency response capability in the face of dangerous events. Aviation security is a non-negligible point in the construction of the smart ocean. The automatic dependent surveillance-broadcast (ADS-B) in the aircrafts is used to broadcast and transmit navigating data, including the call sign of aircraft, altitude in the airspace, current heading of destination, and other locating messages. This paper studies ADS-B security threats such as distributed denial of service attacks and proposes the use of an encryption algorithm to process ADS-B plaintext to improve urban resilience of the smart ocean.
