Abstract

The embodiments of the present application relate to the field of communication transmission security technology, and in particular to a method, device, and mobile terminal for detecting security holes in an air interface protocol. The method for detecting security holes in an air interface protocol includes the steps of: acquiring mutation data generated by a fuzz test task, acquiring a service message of an air interface protocol, modifying the service message based on the mutation data, sending the modified service message to a base station, and monitoring the status of the base station and recording a security hole log according to the status of the base station.
