  abstract = {The debate over ``exceptional access''---the government's
		  ability to read encrypted data---has been going on for many
		  years and shows no signs of resolution any time soon. On
		  the one hand, some people came it can be accomplished
		  safely; others dispute that. In an attempt to make
		  progress, a National Academies study committee propounded a
		  framework to use when analyzing proposed solutions. We
		  apply that framework to the CLEAR protocol and show the
		  limitations of the design.},
