Provisioning of Symmetric Keys
charter-ietf-keyprov-04

Current developments in deployment of Shared Symmetric Key (SSK) 
  tokens have highlighted the need for a standard protocol for 
  provisioning symmetric keys.
  
  The need for provisioning protocols in PKI architectures has been 
  recognized for some time. Although the existence and architecture of 
  these protocols provides a feasibility proof for the KEYPROV work 
  assumptions built into these protocols mean that it is not possible 
  to apply them to symmetric key architectures without substantial 
  modification.
  
  In particular the ability to provision symmetric keys and associated 
  attributes dynamically to already issued devices such as cell phones 
  and USB drives is highly desirable. The working group will develop 
  the necessary protocols and data formats required to support 
  provisioning and management of symmetric key authentication tokens, 
  both proprietary and standards based.
  
  Input Documents
  ---------------
  
  The following Internet drafts have been proposed by their authors as 
  input documents:
  
  * Dynamic Symmetric Key Provisioning Protocol (M. Pei, S. Machani)
  * Portable Symmetric Key Container (A. Vassilev, J. Martinsson, M. 
  Pei, P. Hoyer, S. Machani)
  * Extensions to CT-KIP to support one- and two-pass key 
  initialization (M. Nystroem, S. Machani)
  
  Scope and Deliverables
  ----------------------
  
  The scope of the working group shall be to define protocols and data 
  formats necessary for provisioning of symmetric cryptographic keys 
  and associated attributes.
  
  The group shall consider use cases related to use of Shared Symmetric 
  Key Tokens. Other use cases may be considered for the purpose of 
  avoiding unnecessary restrictions in the design and ensure the 
  potential for future extensibility.
  
  The working group will produce the following deliverables:
  
  * Portable Symmetric Key Container
  * Dynamic Symmetric Key Provisioning Protocol
