Internet - Draft Usc / Isi

Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress." Abstract This document limits the KEY resource record to only DNS zone keys. The original KEY resource record used sub-typing to store both DNS zone keys and arbitrary application keys. DNS security keys and application keys differ in almost every respect and should not be combined in a single sub-typed resource record. This document removes application keys from the KEY record by redefining the Protocol Octet field in the KEY RDATA. Three existing application key sub-types are changed to historic, but the format of the KEY record is not changed. This document updates RFC 2535.
