Abstract

I’d planned to talk about usability and maintainability – in my view, likely to be the two most important research topics in security over the next five years. As everybody’s talked about usability, I will talk a bit more about maintainability.

In the old days we always considered that security was about bootstrapping. Once Alice and Bob could be induced to share a key, job done: we go off down the pub and the following day we write the paper. This is a bit like software engineering 30 years ago where people just studied the waterfall model. But the real world nowadays is different. Nobody’s interested in waterfall; everybody’s interested in evolutionary development, extreme programming and so on. The maintenance is the product - because almost all your costs fall at points in the system development lifecycle other the first one.
