description The invention discloses a vehicle-mounted application system communication security detection method and system. The method comprises the following steps: acquiring and storing a plurality of groups of communication data of a to-be-detected vehicle-mounted application system; analyzing the plurality of groups of communication data to obtain a modulation mode and a coding mode of communication of the vehicle-mounted application system; according to a protocol reverse analysis method, analyzing protocol grammar and voice of the communication data to obtain a feature field corresponding to the output parameter in each data frame; modifying a feature field of each data frame in the communication data to obtain a test data set; modulating, coding and equally-spaced splicing the test data set to generate a test signal; according to the method, the test signal is converted from the real data frame of the vehicle-mounted application system, the data pertinence is higher, the test result is more rational, a tester is
