S-DV: A new approach to Secure Distance Vector routing protocols
Abdelaziz Babakhouya, Yacine Challal, Abdelmadjid Bouabdallah, Saïd Gharout · 2006
The distance vector (DV) routing protocols (e.g., RIP) have been widely used in the Internet. These protocols are vulnerable to a variety of attacks since they were designed without security aware. In this paper, we propose a new approach called S-DV to secure distance vector routing protocols. The main idea is to designate some trusted routers, which we called S-DV routers, which collaborate in consistency checking of routing update messages. These routers maintain also a security metric which is used to forward data traffic through a secure route. Our threats analysis and comparison show that S-DV offers a deterministic detection of malicious routing updates with reduced overhead compared to S-RIP
