Questioning What You Think You Know

Abstract A great deal of the trust we think we can place (or not) in our computing systems is based on exerperience with the ones we commonly use. However, those computing systems continue to be victimized by a variety of failures and attacks. Perhaps some of the "common knowledge" on which we base our designs is itself faulty? Perhaps we are employing concepts that should be re-examined?

I intend to provoke the audience with this talk to question some assumptions related to computer architecture, the definitions of security, and how best to build trusted systems. In particular, we should question if the current methods of defining security are appropriate, how we might better design a system to be secured, and whether we understand the appropriate tradeoffs when paying for heightened trust.

Trusted Computing Rants, Regrets, and Research

Abstract How do we build trustworthy hardware, and how can we use that to increase the trustworthiness of broader distributed computation? These questions have followed me through a variety of venues in my career so far: academia, government, start-up, large industry, and academia again. This talk presents some things I've learned, some things I wish I had done differently, and some things I'd still like to do.

Online Trust: A Decade of Researching Users' Inferences

Abstract Over the past 10 years the question of what makes people trust websites, companies, and other people online has been a recurrent theme. It has been discussed by human-computer interaction specialists (or, to pick today's term, user experience professionals), economists, security experts, and market researchers.

The question is - what can we learn from the combined efforts?

Rather than trying to answer this question outright, I'll look at how the discourse has evolved over this time. While we are still talking about 'online trust', the concerns and goals of our research may have changed.

As an example, in the nineties many studies were conducted to identify the cues that lead users to place trust in e-commerce sites and use their credit cards online. Today we are faced with the reality of phishing attacks (whose designers may well have had a close look at those early publications) and we wonder how we can create systems with reliable cues that allow users instant and correct inferences. Another example are reputation systems, where much effort is spent on safeguarding them against malicious attackers, but only recently the discussion has begun on provisions to avoid the escalation of the accidental mundane transgressions that are so common in our everyday encounters.

My view in tracing these developments will be a user-centred one. I'm more interested in people's perceptions of trustworthiness than in system attributes. I'll draw on my own academic research in e-commerce, online gaming, and online advice - as well as that of others in the field.
