Fuzzing Test Method Based on Constraint-Conditions Priority for LTE-EPC Protocol

Through the analysis of LTE EPC protocol, This paper research the LTE protocol format and tries to find an effective method for security detection. This paper uses fuzzing test techniques to detect security issues in the LTE core network. In order to improve the efficiency of the fuzzing test, this paper proposes a new algorithm based on constraint-condition priority. Finally, this paper tested new algorithm based on OAI LTE core network system and chose a LTE protocol named DIAMETER. The newly proposed algorithm finds a problem with the DIAMETER protocol. By statistical data packet effective rate, it can be proved that the fuzzing test method based on constraint condition priority is effective
