comment What does working in cybersecurity look like?
@AlanSimonin: I'm not sure there is such thing as an MSc in "general CS". But for what it's worth, I had an MSc in theory of programming/formal methods, and I did my PhD in security (from a formal methods aspect though). The best in your case would be to first find a topic you'd be interested in for your PhD, and then to contact a potential advisor to discuss the possibilities.

@Jacco : If you look for the title of the papers on Google, you can directly get the versions the authors put on their webpage.

comment Open Problems in Security?
Thanks, you make a very good point by relating security problems to more "traditional" software problem. However, correct me if I'm wrong, but it seems that most problems you mention are not really open, but just hard. For instance, the halting problem is not open: we know that it's undecidable to know whether a program (including security programs) stops or not. Similarly, we know that in general, because of aliasing, an assignment may have a different effect according to the context. Unless you were thinking about something more specific, which would be very interesting to discuss!

@logicalscope Thanks, but as I mention above, I'm more interested in research topic, that is "open problem in the sense that there might exist a solution, but we don't know it yet", rather than "hard problems that we can't solve efficiently".

@RoryAlsop Thanks! I hope too, I was actually talking with some colleagues, and we realized that we couldn't think immediately at some known open problems, so that's why I hope some people here can hep :)

@RoryAlsop Yes, I actually cite this question already in my question, and I'm rather interested in theoretical/research problems, while it seems (but I might be wrong) that this question focuses more on concrete implementation problems. It also seems that the answers given for this question show unsolvable problems rather than open ones.

Well, actually, I'm more interested in non-crypto problems, as they already have quite well defined problems. Thanks for pointing this out, I will update my question!
