I'm not active in the field right now, so I can't give specifics (the comment was more borne out of frustration with people putting in so much effort 'reinventing the wheel' in an academic sense).
But if I was you, I'd start with Knuth (he, as another commenter mentioned, covers hashes in great detail), head to the references, and then use Google Scholar to find well-cited recent articles that reference the important papers mentioned there.
