摘要

GPRS隧道协议(GTP)缺乏固有的安全性，使得GPRS网络存在安全漏洞。提出了一种防止网络计费过高的新方案。该方案只需要GTP防火墙的动态内存来存储一些信息流(如隧道ID)。它不需要像某些现有解决方案那样在Gi端口上与额外的防火墙一起工作。

Firewall Based Scheme to Prevent GPRS Overbilling

The lack of inherent security in the GPRS tunneling protocol (GTP) leaves security vulnerabilities in GPRS networks. A novel scheme to defend the network against overbilling is proposed. The scheme only requires a dynamic memory in a GTP firewall to store some information flow such as tunnel ID. It needs not work jointly with an extra firewall at the Gi port as in some existing solutions.
