  • Abstract:
  • IPv6, as the foundation for future internet and IT growth, offers features like a vast address pool, extendable headers, enhanced security, and mobility. A critical component of IPv6 is the Neighbor Discovery Protocol (NDP), which facilitates address resolution, router discovery, and duplicate address detection within local-link networks. However, NDP's trust-based design makes it vulnerable to attacks such as Denial of Service (DoS) on Duplicate Address Detection (DAD), Address Resolution attacks, Router Advertisement (RA) attacks, and Redirect attacks. To address these vulnerabilities, this study introduces an NDP security mechanism (NDPsec) utilizing Ed25519 digital signatures to authenticate IPv6 hosts and prevent unauthorized network access. Compared to existing mechanisms like Secure NDP (SeND), Match-Prevention, and Trust-ND NDPsec demonstrates superior performance, achieving 144% faster processing, over 50% reduced traffic overhead, and enhanced resilience against network attacks in experimental evaluations.
