RFC 2528 PKIX KEA March 1999

Abstract

The Key Exchange Algorithm (KEA) is a classified algorithm for exchanging keys. This specification profiles the format and semantics of fields in X.509 V3 certificates containing KEA keys. The specification addresses the subjectPublicKeyInfo field and the keyUsage extension.

1. Executive Summary

This specification contains guidance on the use of the Internet Public Key Infrastructure certificates to convey Key Exchange Algorithm (KEA) keys. This specification is an addendum to RFC 2459, "Internet X.509 Public Key Infrastructure: Certificate and CRL Profile". Implementations of this specification must also conform to RFC 2459. Implementations of this specification are not required to conform to other parts from that series.

2. Requirements and Assumptions

The goal is to augment the X.509 certificate profile presented in Part 1 to facilitate the management of KEA keys for those communities which use this algorithm.

2.1. Communication and Topology

This profile, as presented in [RFC 2459] and augmented by this specification, supports users without high bandwidth, real-time IP connectivity,...
