IESG Note

Section 4.4.4.2 states, "All implememtations within the IPSEC DOI MUST support ESP_DES...". Recent work in the area of cryptanalysis suggests that DES may not be sufficiently strong for many applications. Therefore, it is very likely that the IETF will deprecate the use of ESP_DES as a mandatory cipher suite in the near future. It will remain as an optional use protocol. Although the IPsec working group and the IETF in general have not settled on an alternative algorithm (taking into account concerns of security and performance), implementers may want to heed the recommendations of section 4.4.4.3 on the use of ESP_3DES.

1. Abstract

The Internet Security Association and Key Management Protocol (ISAKMP) defines a framework for security association management and cryptographic key establishment for the Internet. This framework consists of defined exchanges, payloads, and processing guidelines that occur within a given Domain of Interpretation (DOI). This document defines the Internet IP Security DOI (IPSEC DOI), which instantiates ISAKMP for use with IP when IP uses ISAKMP to negotiate security associations.

For a list of changes since the previous version of the IPSEC DOI, please see Section 7.

2. Introduction

Within ISAKMP, a Domain of Interpretation is used to group related protocols using ISAKMP to negotiate security associations. Security protocols sharing a DOI choose security protocol and cryptographic transforms from a common namespace and share key exchange protocol identifiers. They also share a common interpretation of DOI-specific payload data content, including the Security Association and Identification payloads.

Overall, ISAKMP places the following requirements on a DOI definition:

o define the naming scheme for DOI-specific protocol identifiers o define the interpretation for the Situation field o define the set of applicable security policies o define the syntax for DOI-specific SA Attributes (Phase II) o define the syntax for DOI-specific payload contents o define additional Key Exchange types, if needed o define additional Notification Message types, if needed

The remainder of this document details the instantiation of these requirements for using the IP Security (IPSEC) protocols to provide authentication, integrity, and/or c...
