"Dynamic Symmetric Key Provisioning Protocol (DSKPP)", Andrea Doherty, Mingliang Pei, Salah Machani, Magnus Nystrom, 25-Feb-08. ( bytes)

DSKPP is a client-server protocol for initialization (and configuration) of symmetric keys to locally and remotely accessible cryptographic modules. The protocol can be run with or without private-key capabilities in the cryptographic modules, and with or without an established public-key infrastructure. Two variations of the protocol support multiple usage scenarios. With the four-pass variant, keys are mutually generated by the provisioning server and cryptographic module; provisioned keys are not transferred over-the-wire or over-the-air. The two-pass variant enables secure and efficient download and installation of pre- generated symmetric keys to a cryptographic module. This document builds on information contained in [RFC4758], adding specific enhancements in response to implementation experience and liaison requests. It is intended that this document or a successor version thereto will become the basis for subsequent progression of a symmetric key provisioning protocol specification on the standards track.

"Portable Symmetric Key Container", Philip Hoyer, 22-Apr-08. ( bytes)

This document specifies a symmetric key format for transport and provisioning of symmetric keys (for example One Time Password (OTP) shared secrets or symmetric cryptographic keys) to different types of crypto modules such as a strong authentication device. The standard key transport format enables enterprises to deploy best-of-breed solutions combining components from different vendors into the same infrastructure. This work is a joint effort by the members of OATH (Initiative for Open AuTHentication) to specify a format that can be freely distributed to the technical community. The authors believe that a common and shared specification will facilitate adoption of two- factor authentication on the Internet by enabling interoperability between commercial and open-source implementations.

"Symmetric Key Package Content Type", Sean Turner, Russ Housley, 25-Feb-08. ( bytes)

This document defines the symmetric key format content type. It is transport independent. The Cryptographic Message Syntax can be used to digitally sign, digest, authenticate, or encrypt this content type.
