This report, written in 2009 following the inaugural symposium of the DNSSEC Industry Coalition but unpublished until now, covers issues that remain important to ongoing DNSSEC deployment efforts. Written before the signing of the root zone, the “avoiding unintended consequences” section has been superseded by events, but the discussions of key distribution and use and key rollover remain as critical as ever for DNS and DNSSEC practitioners.  [Note that this PDF contains comment markup from symposium participants.]
