<div dir="ltr"><div>Dear colleagues,</div><div><br></div><div><br></div><div>Yesterday, JNSA had a meeting to discuss issues around</div><div>XAdES in OPC. Here is a quick summary (I will prepare </div><div>a longer version).</div><div><br></div><div>1) DSig version: 1.1?</div><div><br></div><div>1.1 only</div><div><br></div><div>2) Canonicalization algorithms?</div><div><br></div><div>Must support 1.0, 1.1, and ExcC14N without comments,</div><div>should support 1.0, 1.1, and ExcC14N with comments,</div><div><br></div><div>3) XAdES Version: EN or TS? (EN only)</div><div><br></div><div>EN only</div><div><br></div><div>4) Which spec from ETSI?</div><div><br></div><div>Part 1 of XAdES as well as AdES</div><div><br></div><div>5) New relationship type for XAdES EN digital signatures part?</div><div><br></div><div>No. Implementations should be able to distinguish new and </div><div>old XAdES signatures.</div><div><br></div><div>6) SignatureTime of OPC?</div><div><br></div><div>Do not use SignatureTime for display or validation when there is</div><div>a time stamp. Clearly show to users whether a time stamp or SignatureTime</div><div>is used.</div><div><br></div><div><br></div><div>Regards,</div><div>Makoto</div><div><br></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">2015-12-20 16:13 GMT+09:00 MURATA Makoto <span dir="ltr"><<a href="mailto:eb2m-mrt@asahi-net.or.jp" target="_blank">eb2m-mrt@asahi-net.or.jp</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Folks,</div><div><br></div><div><span>JNSA</span> and the Japanese mirror plan to provide a detailed proposal for</div><div>the <span>intrudction</span> of <span>XAdES</span> into <span>OPC</span>.
