Findings
PKBU effectively prevents false binding updates.
PKBU mitigates man-in-the-middle attacks.
PKBU reduces susceptibility to DoS attacks.
Abstract
Mobile IPv6 control signalling messages generally act as informants to the home agent (HA) and the correspondent node (CN) regarding a mobile node's (MN's) new address when its network attachment point changes. Messages should be protected to avoid different security attacks. In the existing standard, control signalling messages between HA and MN are frequently authenticated with IKEv2 and X.509 certificates via IPSec. These signalling messages between MN and CN are so far protected by an effective but insecure protocol. A protocol that uses Binding Update Route Optimisation has security vulnerabilities that allow redirection of traffic by attackers. This traffic is intercepted and then false binding updates is sent along with packet eavesdropping and Denial of Service (DoS) that disrupts any communication. Due to lack of ineffective authentication procedures to ascertain the validity…
