Apologies to those who don't think this excellent paper by Rogaway has 
anything to do with ICANN. I think it does and wanted to draw it to your 
attention in case you do not usually look at papers on cryptography.  I 
am indebted to the EPIC advisors list for drawing my attention to it and 
to its importance.  It has a broad scope, but frames many of the 
troubling issues in balancing security and privacy rather well, and 
holds important lessons for us working on those issues here at ICANN.
