PhD Thesis in IT Security

This is what a business in Sweden was looking for in their book cover design

I need a design for the cover of my PhD thesis in software security. The design should incorporate a simple graph with four nodes since it represents one of my research results. I like the color orange and would probably like it as a base color for the design.
I already have the university's official template, formatted for Adobe InDesign (.indd uploaded here, not with my title or abstract since I can't edit it). They also provide a poor man's PowerPoint template (.ppt uploaded here _with_ my title and abstract, so please use the text info from the .ppt in your design).
The .indd template uses a paid font and has the university's official logo in light blue. They can switch to the paid font themselves if I can't provide a design with it. Having them change the font gives us less control but might be an option. Please indicate if you've used the right font or not. Read more
