If the key consist of perfectly random bits and is not reused, then this is actually an implementation of a one time pad, not a block cipher. – Maarten Bodewes. Oct 1, 2013 at 19:39. If this were an algorithm rather than an example it might be a block cipher. But it might just as well be a one time pad, or something else.
