+ <abstract>
+<p>
+Instant messaging (IM) is an increasingly popular mode of communication
+on the Internet. Although it is used for personal and private
+conversations, it is not at all a private medium. Not only are all of
+the messages unencrypted and unauthenticated, but they are all
+routedthrough a central server, forming a convenient interception point
+for an attacker. Users would benefit from being able to have truly
+private conversations over IM, combining the features of encryption,
+authentication, deniability, and forward secrecy, while working within
+their existing IM infrastructure.
+</p>
+<p>
+In this talk, I will discuss "Off-the-Record Messaging" (OTR), a widely
+used software tool for secure and private instant messaging. I will
+outline the properties of Useful Security and Privacy Technologies that
+motivated OTR's design, compare it to other IM security mechanisms, and
+talk about its ongoing development directions.

+Ian Goldberg is an Assistant Professor of Computer Science at the
+University of Waterloo, where he is a founding member of the
+Cryptography, Security, and Privacy (CrySP) research group. He holds a
+Ph.D. from the University of California, Berkeley, where he discovered
+serious weaknesses in a number of widely deployed security systems,
+including those used by cellular phones and wireless networks. He also
+studied systems for protecting the personal privacy of Internet users,
+which led to his role as Chief Scientist at Zero-Knowledge Systems (now
+known as Radialpoint), where he commercialized his research as the
+Freedom Network.
