This study provides a simple variation of the protocol of quantum key expansion proposed by Hwang. Some weaknesses relating to the step of public discussions for error detection are analyzed and an attack strategy, allowing the eavesdropper to get partial information about the used bases, is put forward. Using the One-Time Pad cipher, we propose a possible scheme which is secure against the presented attack.
