XML WS-Man / CIM Affiliation
Proposal to leverage WS-Management transport protocol specifications for the
message transport protocol. The proposal also include a means to affiliate the
1619.3 objects and operations model to CIM to provide a method of
mechanically binding the 1619.3 object model to the transport protocol via the
CIM Binding and WS-CIM Mapping specifications.

Resources Required to implement KM Client
WS-Management stack with WS-Eventing, including XML parser and HTTP 1.1
compatible protocol implementation = 65KB optimized code size. TLS 1.0
package with server side certificate support = 68KB optimized code size. Entire
secure web service interface runs in approximately 150KB RAM.

Code for the included sizing info was written in ANSI-C and requires libc and
uses NetX TCPIP stack running in ThreadX. Another implementation only had
libc as a dependency.

Many systems vendors and silicon eco-system component providers have
products available today that implement the WS-Management protocol. The
opportunity to align the 1619.3 key management protocol with these
implementations will increase the likelihood of adoption of 1619.3 as it will be
incremental capability on existing infrastructure.

Not sure what the criteria is for measuring execution speed but several
implementations have demonstrated the ability to handle at least dozens of
request/response transactions per second.
For our purposes, XML SOAP defines a way to pass strongly typed data on a
remote procedure call through HTTP(s). The interfaces to the service are
defined in a WSDL file.

Resources required to implement KM Client
We have a statically linked library that is ~470KB (including libxml2 and libcurl);
however, I am sure this could be much smaller

xml SAX/DOM (libxml2 for instance) (if parsing yourself, need library to handle
non-ASCII processing), sockets/ssl or perhaps HTTPs (openssl/curl for instance)

No hard numbers; it seems like messages can be more compact than ws-man,
but larger than binary (obviously).
The SKSML protocol is designed to be used by applications at “Layer 7 of the
application stack” and provides rich capability for defining policies and security of
the payload. However, since it is just another client-server protocol, it can be
used in other layers of the application stack, as needed.

Resources required to implement KM Client
4475187 bytes for Java-based Symmetric Key Client Library (SKCL)

9450324 bytes for Java-based Symmetric Key Services (SKS) server

Java-based StrongKey 1.0 SKS implementation requires the following for the
- RDBMS with JDBC driver
- Java Development Kit
- J2EE Application Server
- Web Services Developer Pack
Java-based StrongKey 1.0 SKCL implementation requires the following for the
- Web Service Security libraries
- Web Service Libraries

SKSML was not designed for small footprint devices such as disk-drive firmware.
It is a heavy protocol (which requires mandatory digital signatures and encryption
using XML Signature/XML Encryption) and was created for PDAs, Laptops,
Desktops & Servers. However, it is recommended that storage manufacturers
can use SKSML between their Management Consoles and the KM server, and the
1619.3 protocol between the MC and the device and use the best of both
protocols for bridging two different environments.
XML (raw)
Extensible Markup Language (XML) is a simple, very flexible text format derived
from SGML (ISO 8879). Using raw XML as a messaging format uses a simple
request and response mechanism to perform all key management functions (i.e.
generate, get, store, etc...)

nCipher KMS toolkit

XML is the standard messaging format for web services as well as many other
service based protocols

Resources required to implement KM Client
Not all Cryptographic Units and/or endpoints have the ability to support XML
messaging due to limited processing power.
Varies based on implementation. Currently none available.

Would potentially require development as an open source project

Specific tools will have specific OS and system requirements that may or may not
be supported by all vendors without custom development

Based on custom messaging performance will tend to be better using targetted
XML messaging versus other formats that may have non-applicable overhead
(SOAP, WSman, etc…)
BINARY (Fixed structure)
Fastest due to complete customization to specific application.
Binary TLV
Binary format constrained by a Tag, Length and Value field.

None defined

nCipher KDP+ protocol

KDP protocol built into existing security devices such as HSM's and off the shelf
encryption chips.

No relevent standards that exist today
Varies by implementation requirements

Varies by implementation requirements

Can be embedded directly into silicon and/or software solutions where the KM
Client and Cryptographic Unit are one and the same

Usually fast due to customization for a specific application
Binary ASN.1 DER
DER is a particular way to encode an ASN.1 structure in an unambiguous way. An
alternative, BER, may be suitable for many of the applications being considered
by P1619.3.

Vendors of commericial ASN.1 products also sell test software -
http://www.asn1.com/products/asn1step.html, for example
As close to ubiquitous as possible - virtually any application of cryptography uses
ASN.1, along with BER and DER encoding.

Depends on the compiler

Probably perferable to XML in most embedded applications

Relatively fast
