           IP Storage: IPsec Requirements Update for IPsec v3
                  draft-ietf-storm-ipsec-ips-update-00

Abstract

   RFC 3723 includes requirements for IPsec usage with IP Storage
   protocols (e.g., iSCSI) based on IPsec v2 (RFC 2401 and related
   RFCs).  This document updates those requirements to IPsec v3 (RFC
   4301 and related RFCs) and updates implementation requirements to
   reflect developments in cryptography since RFC 3723 was published.

1.  Introduction

   RFC 3723 [RFC3723] includes requirements for use of IPsec with IP
   Storage protocols (e.g., iSCSI) based on IPsec v2 (RFC 2401 [RFC2401]
   and related RFCs).  This document updates those requirements to
   include IPsec v3 (RFC 4301[RFC4301] and related RFCs) to reflect
   developments since RFC 3723 was published.  IP storage protocols can
   be expected to operate at high data rates (multiple Gigabits/second);
   the requirements in this document are strongly influenced by that
   expectation, and hence may not be appropriate for other IPsec usage
   that does not involve high data rates.

   In addition to the IPsec v2 requirements in RFC 3723, IPsec v3, as
   specified in [RFC4301] and related RFCs (e.g., IKEv2 [RFC5996]),
   SHOULD be implemented for use of IPsec with IP storage protocols.
   Retention of the mandatory requirement for IPsec v2 provides
   interoperability with existing implementations, and the strong
   recommendation for IPsec v3 encourages implementers to move forward
   to that newer version of IPsec.

   Cryptographic developments since the publication of RFC 3723
   necessitate changes to the encryption transform requirements for
   IPsec v2, as explained further in Section 2.2; these updated
   requirements also apply to IPsec v3.
