As tradition dictates, before I could defend my Ph.D. dissertation 22th November, I had to give a 45 minutes trial lecture. I was given only the title, and had 14 days to prepare. My title was:
"The development of security architecture in fixed and mobile telephone systems"
One of the toughest tasks was to interpret the title and limit the scope of the lecture. I discussed with my supervisors and co-researchers and received several tips and relevant references. Then started two intense weeks with study and preparation.
I was satisfied with the disposition and result, and felt comfortable presenting the lecture.
