[2]This document specifies protocol bindings with security characteristics for the XML Key Management Specification (XKMS).

[2]This document specifies protocols for distributing and registering public keys, suitable for use in conjunction with the W3C Recommendations for XML Signature [XML-SIG] and XML Encryption [XML-Enc]. The XML Key Management Specification (XKMS) comprises two parts — the XML Key Information Service Specification (X-KISS) and the XML Key Registration Service Specification (X-KRSS).

The XML Key Management Specification (XKMS 2.0) [XKMS] aims at providing a PKI independent interface to key management. XKMS services comprise discovery and validation of keys as well as support for certain aspects of the key life cycle management, including registration, reissuance and revocation.

XKMS employs XML Signature [XMLSIG] for the purpose of providing message security in the form of authentication and integrity. In addition, XKMS is based on the use of the <ds:KeyInfo> element as a means of transporting key information used as templates for the various operations it specifies.

This technical note addresses some of the issues related to the use of XKMS in conjunction with PGP [PGP].

The XML Key Management Specification (XKMS 2.0) is a W3C Recommendation that specifies protocols for distributing and registering public keys.

The XML Key Management Service (XKMS) Working Group has defined a Web Service to handle conventional PKI (public-key infrastructure) functions such as registration, revocation and status, as well as related functions such as retrieval.

This note provides a sample Web Services Description Language (WSDL) 1.1 description for an XKMS service. It is intended that XKMS developers use this as a "first draft" for developing their own version. Conversion to WSDL 2.0 should be fairly straightforward, once that specification completes its Last Call.

This document lists the design principles, scope and requirements for XML Key Management specifications and trust server key management implementations. It includes requirements as they relate to the key management syntax, processing, security and coordination with other standards activities.

This document extends the XML Key Management Specification [XKMS] protocol to encompass the bulk registration operations necessary for interfacing with such systems as smart card management systems.

X-BULK is defined in terms of structures expressed in the XML Schema Language [XML-Schema] and web services description language [WSDL].
