Keynote: Usable Security: Happy 20th Birthday! Time to grow up.

Prof. Angela Sasse will reflect on what knowledge can be gathered from the research that has been published on Usable Security and Privacy, and what tangible changes this knowledge has made to user experience of security. She will review how usable security and privacy has often been misunderstood as a path to make users adhere to security and privacy rules that experts deem necessary, which explains why user sentiments towards security remains largely negative. However, she is optimistic that user-centered design will help understand user requirements for security and identify their preferred ways of achieving it.
