<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I don’t think it’s a problem to point to an orange book. According to the publication guidelines yellow book, we have the following rules (with respect to normative references):<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Normative Track Documents and Experimental Specifications<o:p></o:p></p>
<p class="MsoNormal">1) The list shall include publications whose provisions are required for implementing the specifications contained in the document.<o:p></o:p></p>
<p class="MsoNormal">2) If normative references exist, the text used to introduce the list shall be as follows:<o:p></o:p></p>
<p class="MsoNormal">The following publications contain provisions which, through reference in this text, constitute provisions of this document. At the time of publication, the<o:p></o:p></p>
<p class="MsoNormal">editions indicated were valid. All publications are subject to revision, and users of this document are encouraged to investigate the possibility of applying the<o:p></o:p></p>
<p class="MsoNormal">most recent editions of the publications indicated below. The CCSDS Secretariat maintains a register of currently valid CCSDS publications.<o:p></o:p></p>
<p class="MsoNormal">3) The list shall not include the following:<o:p></o:p></p>
<p class="MsoNormal">– materials that are not publicly available;<o:p></o:p></p>
<p class="MsoNormal">– publications to which only informative reference is made;<o:p></o:p></p>
<p class="MsoNormal">– publications that provided only source material in the development of the Recommended Standard, Practice, or Experimental Specification.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Let me however say that I think it would be better to have a pointer to a blue rather than an orange book. Given the fact that here we are “just” dispositioning RIDs and the interoperability testing in not even started (I’m also not sure
whether another agency review might be necessary before the interoperability), I expect that the publication of the BPsec won’t happen before Q1 next year and maybe at that time the BPv7 blue will be there and could directly point to the blue. But as said
formally speaking we can point to the orange.<o:p></o:p></p>

<p class="MsoNormal"><span lang="EN-GB" style="font-family:Aptos">Regarding #16: for me it would be fine to refer to the Orange Book but I am not sure about the rules. Alternatively, there could be a statement that CCSDS BPSEC is applicable to the IPN naming
scheme (old one, I suppose) and that for future naming scheme definitions in CCSDS BPSEC applicability needs to be explicitly stated. I think it is worth considering BPSEC in the multi-destination context (maybe already done and it is just fine but I don’t
really know). <o:p></o:p></span></p>

is confusing. A better term is to say cipher-based authentication when using a symmetric key algorithm to provide authentication, <paragraph break> Using a dual-mode AEAD algorithm supports only cipher-based authentication (i.e., for BCB). For BIB, various
authentication algorithms can be used.<o:p></o:p></span></p>
