Abstract:

   SRv6 is being rapidly deployed and is currently primarily used in
   trusted-domain backbone networks.  However, we have also observed
   that SRv6 is beginning to extend toward end-user devices, e.g., in
   SD-WAN deployments.  SD-WAN can be deployed in third-party clouds or
   at customer sites, causing the physical boundary of SRv6 to become
   blurred.  This introduces certain security risks, such as packet
   injection and path manipulation attacks.  Section 6 of
   [I-D.draft-ietf-spring-srv6-security] identifies these risks as well,
   including Section 6.2.1 on Modification Attacks and Section 6.2.3 on
   Packet Insertion.  This proposal mitigates these risks by enhancing
   the HMAC mechanism defined in [RFC8754].
