Hi,<br>
<br>
adding an HMAC-based authenticator option to secure NDN content is a
good idea. <br>
It certainly makes sense for intranets and other intra-AS settings.
<br>
<br>
I believe that CCNx has introduced an HMAC option quite some time
ago.<br>
It might be worthwhile to check with PARC and not to reinvent the
wheel.<br>
<br>
Cheers,<br>
Gene<br>

<div>I am proposing to add an HMAC type, using SHA256 as the
hash function, to the signature types defined at <a
moz-do-not-send="true"
href="http://named-data.net/doc/NDN-TLV/current/signature.html">http://named-data.net/doc/NDN-TLV/current/signature.html</a>.
This will enable communication with symmetric keys, which
reduces the signing and verification load on
resource-constrained devices.</div>
<div><br>
</div>
<div>The proposal is attached. Please review it and reply with
any comments or suggestions.</div>
<div><br>
</div>
<div>Thanks,</div>
