<p class="MsoNormal">Dear All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My ESA colleagues have been elaborating on a key management scheme for BPSEC, including preliminary prototyping. They would like to present the concept, which builds on the
<a href="https://datatracker.ietf.org/doc/html/draft-burleigh-dtnwg-dtka-01">DTKA draft</a>, in order to receive any comment or feedback from the Security and DTN WGs.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Looking forward to discussing with you.<o:p></o:p></p>
