How much security does Y-00 protocol provide us ?
Tsuyoshi Nishioka, Toshio Hasegawa, Hirokazu Ishizuka, Kentaro Imafuku, Hideki Imai
abstract: New quantum cryptography, often called Y-00 protocol, has much higher
performance than the conventional quantum cryptographies. It seems that the
conventional quantum cryptographic attacks are inefficient at Y-00 protocol as
its security is based on the different grounds from that of the conventional
ones. We have, then, tried to cryptoanalyze Y-00 protocol in the view of
cryptographic communication system. As a result, it turns out that the security
of Y-00 protocol is equivalent to that of classical stream cipher.
