The citation key is the abbreviation the user has to input when using the \cite{...} command. It can be almost anything you want it to be (letters, numbers, dashes, underscores -- I'd avoid other punctuation), but if you're preparing something for others to use, it's best to make it something that a user would find easy to remember. Common styles are author-year or author-shorttitle, e.g., knuth-texbook or knuth1984. I wouldn't make a citation key consist only of numbers -- that's too hard to remember.
