7/14/2003IETF57 PANA enabling IPsec based Access control draft-mohanp-pana-ipsec-00.txt Mohan Parthasarathy Tahoe Networks - Presented by Hannes Tschofenig

7/14/2003IETF57 Enabling IPsec Access control PANA protocol - used to authenticate the client. PANA protocol - also capable of sending Protection-capability-AVP (with PANA-Bind- Request) asking (enforcing) the client to use L2 or L3 cipher. But PANA protocol does not specify the details on how the L2/L3 SAs are established etc. This draft essentially discusses the details of using IPsec as the L3 cipher.

7/14/2003IETF57 Pre-requisites for using IPsec PANA client (PaC) should learn the IP address of the enforcement point (EP) during the PANA exchange. PaC learns that the network uses IPsec for securing the PaC-EP link. PaC has already acquired an IP address and PAA knows about the IP address of the PaC before the exchange starts.

7/14/2003IETF57 IKE/IPsec details At the end of a successful authentication, a PANA SA is established between PaC and PAA (assuming the underlying EAP method is capable of generating a Master Key (MK)). IKE pre-shared key is derived from the PANA SA (TBD). EP securely receives the following from PAA: - IKE pre-shared key - IP address of PaC - PANA session id

7/14/2003IETF57 IKE/IPsec details (contd..) Manual keying not supported. IKE is used to establish IPsec SAs. Both Aggressive mode and Main mode is easy to support. In main mode, PaC and EP uses the IP address as the client identifier. In Aggressive mode, PaC and EP use the PANA session id as identifier - part of ID_KEY_ID payload.

7/14/2003IETF57 IKE/IPsec details (contd..) After Phase I SA is established, quick mode exchange is performed to setup an IPsec SA. Quick mode IPsec SA is an ESP transport mode SA used in conjunction with IP-IP tunnel interface (IP-IP transport mode SA). IPsec tunnel mode SA also can be used.

7/14/2003IETF57 IPv4/IPv6 Details Draft has specific examples on SPD entries, IPsec processing details for both IPv4 and IPv6. In IPv4, the SPD entries are very simple. All of the traffic is tunneled to the security gateway (EP). In IPv6, there are a few exceptions. EP is the security gateway – a router. Implies hop count is decremented by 1. This won’t work for RD/ND messages which assume nhop count = 255.

7/14/2003IETF57 IPv4/IPv6 details (contd..) As IPsec selectors are not capable of expressing bypass rules for ND/RD messages: - Use just fe80::/10 as the on-link prefix i.e., all other packets are sent to the default router. - Bypass IPsec for packets destined to fe80::/10. All packets are tunneled to the link-local address of the EP.

7/14/2003IETF57 Double IPsec If the PaC uses IPsec for secure remote access, there will be separate SPD entries for protecting the remote network traffic. Packets will be protected twice. Once for the remote network and once for the local network. This case of iterated tunneling is discussed in RFC2401 (IPsec).

7/14/2003IETF57 Open Issues IKE pre-shared key derivation from PANA SA. Use IPsec tunnel mode to describe the IPsec details instead of IP-IP transport mode.

7/14/2003IETF57 Question to WG Should we make this a WG I-D?
