    "abstract": "This paper provides a simple variation of the basic ideas of the BB84 quantum\ncryptographic scheme leading to a method of key expansion. A secure random\nsequence (the bases sequence) determines the encoding bases in a proposed\nscheme. Using the bases sequence repeatedly is proven to be safe by quantum\nmechanical laws.",
