I’ll be the first to admit that I obsess over security. My internship in college dealt with Unix security. I’ve created encrypted protocols for wireless data communication. And for my master’s thesis, I created a highly virus-resistant computer architecture (AHVRC – aka Aardvark). I wrote it in 1993. I put it up on the web in 1999.

So, what to my wondering eye did appear a few days ago? None other than the latest installment of Apples “iOS Security” document.

Personally, I like reading Apple documentation. But then again, I read owner’s manuals. Anyway …

So, I find myself reading iOS Security and keep thinking, “that’s what I would have done.” Wait, that’s what I did do.

I was casting about for a thesis topic and my department chair noted that no one was doing anything in secure architectures. So I spent a chunk of time thinking and put a little 124 page missive together. Now gentle reader, you having taken it upon yourself to read a few pages in begin thinking, “this can’t be serious, it’s got animals instead of sub-systems.” True, true. The master level is supposed to have a certain level of awe and wonder associated with it. Boring. Here’s a little secret. In a traditional master’s program, you devote the equivalent of three courses to the research and writing of a document (thesis). The point of the thesis and its defense demonstrates mastery of the discipline. The defense is done publicly. Anyone may attend. You must advertise it to the student body. Some number of professors, typically in your discipline and of your choosing, make up the group who decide if you and your work are up to snuff. Question may be asked in any area of your studies, but primarily the discussions will revolve around your thesis. Hence, being called a defense. Once the professors have had at you, the gallery gets their shots.

You already knew that didn’t you. Well, that’s not the secret.

The secret is that the defense is conducted within the context of the thesis. They attack, but you get the build the world. Think of it as a duel. You get to choose the weapons.

Nothing warms the cockles of my heart more than to see the distinguished faculty discussing a highly technical matter in the context of dolphins, gophers and kinkajous.

I even applied (with Rose-Hulman generously funding) for a patent. Had I had more patience and a more informed examiner at USPTO, I probably would have a patent for the work.

I’m not sure if the developers at Apple ever read my thesis or referenced my patent filing. I do find the similarities in the two architectures interesting.

I hope everyone who reads this posting takes the opportunity to read both documents. Apple’s because they present the state-of-the-art in application security model implementation. Mine, because I think I’m pretty well pleased with myself about it.
