Description
Background
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
