| Abstract: | As the neural system of telecommunication network,the security problem of signaling system 7(SS7) becomes more serious.The main security threats of SS7 are listed in this paper,analyse the security flaw due to lack of authentication and how the attckers make use of the management messages of the MTP3 layer to attck the SS7 network,then propose security solution to protect MTP3 layer in SS7,using Key Exchange protocol and Authentication Header protocol,by which the security of SS7 network is enhanced. |
