I suppose we may want to amend HamWAN's official Mission statement
to better reflect the recent work in developing software and
networking standards. The stuff we released so far in this realm
is:<br>

Without Encryption</a><a href="http://hamwan.org/Standards/Network%20Engineering/Authentication/SSL%20without%20Encryption.html" target="_blank"><br>
</a></li>
<li><a href="http://hamwan.org/Standards/Network%20Engineering/Authentication/SSL%20without%20Encryption.html" target="_blank">SSL

</li>
<li><a href="http://hamwan.org/Labs/Open%20Peering%20Policy.html" target="_blank">Open
Peering Policy</a></li>
<li><a href="http://hamwan.org/Standards/Network%20Engineering/High%20Availability.html" target="_blank">High
Availability</a></li>
<li><a href="http://hamwan.org/Standards/Network%20Engineering/Cell%20Site%20Configuration/Servers.html" target="_blank">Some
other Server suggestions</a></li>
<li><a href="http://hamwan.org/Standards/Network%20Engineering/Point%20to%20Multipoint%20Authentication.html" target="_blank">Point
to Multipoint Authentication</a></li>
<li><a href="http://hamwan.org/Standards/Network%20Engineering/Quality%20of%20Service.html" target="_blank">Quality
of Service</a><br>
</li>
</ul>
Some of these are better than others. Many of these need more
work. Specifically, only the SSH solution is "finished", I think.
The unpublished work going on right now is focused on automation and
robustness of network services. I got some good engagement in the
previous thread I sent out on distributed filesystem implementations
(most of it in private email), and that left me with a few options
to verify in the lab and on the HamWAN network. This identity
thread doesn't quite have the same expert engagement though, so the
quest continues.<br>
<br>
At the inevitable risk of offense, I don't see what ARETF offers to
be leveraged. Having surfed the site, forum and github repo, it's
pretty much empty. What this work requires is active, dedicated
engineers who have a deep understanding of how things work in this
space. Show me where THOSE people are, and I'll happily join the
group.<br>
<br>
Why can't ARETF's mission be executed within HamWAN? We have a
small but growing set of engineers who are well versed in the
digital world. We also have the added benefit of real-world use
cases, so you don't fall into the pit of designing-for-everybody on
your first iteration.<br>
<br>
Having said all that, I don't think the entirety of what's needed to
service emcomm (and likely even ham) users can be implemented in
HamWAN's current organizational model. Motivating said skilled
engineers to execute consistently and on-time (or even at all) has
been one major impediment to success. Lately I've been studying the
viability of remunerating engineering work in this problem space.
The most surprising finding to date is that some folks have a
philosophical opposition to getting paid for their work product in
this problem space. Feel free to contact me privately (goes for
anyone) if you're interested in this latest viability study of mine.<span class="HOEnZb"><font color="#888888"><br>

amateur radio, we want to be able to use all of the
security features above except for privacy. It's a
common misconception in the US that FCC part 97
prevents the use of encryption and therefore most
security features aren't available to us. However,
what part 97 actually prohibits is "messages encoded
for the purpose of obscuring their meaning." It's
important to keep this distinction in mind when
developing best practices and communicating them to
users who may not understand the difference.</p>

many technologies already support these features
without privacy which means we don't need to start
from scratch. Unfortunately, privacy is the one
thing most people think of when it comes to
security. Therefore, our use-cases don't tend to be
well documented or understood. That's what I hope
we get a chance to fix.</p>

No, not that kind of identity. Digital
identity. Used to inform networks and
computers about who you are. In my brief
research on this, Wikipedia has listed a few
systems:<br>
<ol>
<li>SAML</li>
<li>OAuth</li>
<li>OpenID</li>
<li>CAS</li>
</ol>
<p>There are of course other systems, such as
X509 certificates, or just plain old trusted
keys or fingerprints. The question is,
which of these systems are appropriate for
use on Part 97 airwaves?<br>
</p>
<p>The big P97 restriction we have is no use
of secrecy or encryption. Early on we
realized this means any system which relies
on shared secrets (such as passwords) is not
going to work well. One system that does
work really well is public/private key based
authentication. SSH key authentication and
TLS client certificate authentication work
really well because of this. However, those
systems are not without problems. Both of
them need to have the encryption option
turned off, which requires a custom ssh
client and server for SSH, and is nearly
impossible to do with any modern web browser
for TLS. Other applications that use TLS
will also have the same challenge.<br>
</p>
<p>I'd like to identify some acceptable
identity systems for web browsers and web
applications. It would be great if they
could also be used for email clients
(Thunderbird, Evolution, KMail, etc), and
other applications like file shares.<br>
</p>
<p>I haven't looked into security tokens at
all yet, but those may work. That is, to
plug a token into USB or tap it via NFC
(cell phone case), and have yourself
identified.<br>
</p>
<p>Is anyone aware of which systems may be
compatible with Part 97 and work in a
user-friendly way?<span class="m_-5655051895472301058m_3457861431838574063HOEnZb"><font color="#888888"><br>
