Quantum cryptography without public announcement of bases
We give a simple variation of the basic ideas of the BB84 quantum cryptographic scheme leading to a method of key expansion. A secure random sequence (the bases sequence) determines the encoding bases in a proposed scheme. Against incoherent attacks by Eve, using the bases sequence repeatedly is proven to be safe by quantum mechanical laws. (C) 1998 Elsevier Science B.V.
