Mobile core network uses Signaling System No. 7 (SS7) as its signaling system. SS7 takes charge of call setup, roaming, teardown messages, database queries and so on, and becomes the important goals of the attackers or the stealers as there is a large number of user’s information, such as identity, location, and service, contained in signaling messages. The use of MTPsec at MTP3 layer in SS7 protocol stack is a good solution to provide secure protection for signaling messages in 3G core network.
