This document provides guidance to designers of Authentication,
Authorization, and Accounting (AAA) key management
protocols. The guidance is also useful to designers of systems and
solutions that include AAA key management protocols. Given the
complexity and difficulty in designing secure, long-lasting key
management algorithms and protocols by experts in the field, it is almost
certainly inappropriate for IETF working groups without deep expertise in
the area to be designing their own key management algorithms and
protocols based on Authentication, Authorization, and Accounting (AAA)
protocols. The guidelines in this document apply to documents requesting
publication as IETF RFCs. Further, these guidelines will be useful to other
standards development organizations (SDOs) that specify AAA key management. This document specifies an Internet Best Current Practices for the
Internet Community, and requests discussion and suggestions for
improvements.
