| 摘要: |
| 七号信令网络由于缺乏安全机制而存在诸多安全漏洞。通过分析攻击者如何利用MTP3层的网络管理消息对七号信令网实施攻击,提出用密钥交换协议和认证头协议对MTP3层进行安全保护,从而实现了信令节点间的相互认证和对消息的完整性保护,增强了七号信令网络的安全性。 |

| Analysis of Secure Strategy Based on MTP3 Layer in SS7 Networks |

| Abstract: |
| There are several security leaks in signaling system 7(SS7)networks for the lack of security mechanism.After analysing how the attacker makes use of the management messages of the MTP3 layer to attck the SS7 network,the key exchange protocol and authentication header protocol are proposed to provide mutual authentication between signaling points and integrity protection of messages,and the security of SS7 network is enhanced. |
