I am interested in pursuing an area of computer security that is very likely already being studied by security professionals in industry and perhaps the military as well. Some of it is published, but I imagine some of it could also be unpublished work that companies and the military might not want to share with the public.
I could see my research group independently developing some unpublished techniques that probably are already in use in some form or another by existing companies who don't wish to share those to the public. In this case, is it acceptable for me to publish this as my own research, given that I have no affiliation to the company in question (assuming such a company does exist, which could very well be the case)? If I do publish, can I be in trouble for publishing work which these companies/military don't want the public to be aware of (but which I developed independently)?
