Paper Abstract

The notion of the deliberate error randomization (DER) for the Y-00 quantum stream cipher was introduced by Yuen [arXiv:quant-ph/0311061v6], and concrete schemes of DER were proposed by the author for the phase shift keying Y-00 quantum stream cipher (PSK-Y00) [Proc. SPIE 6305, 630508 (2006)]. In this paper, it is shown that one of our DER schemes, which was referred to as Model B in the literature, is applicable to the intensity shift keying Y-00 quantum stream cipher (ISK-Y00) and the brute-force search complexity Q in the case of ISK-Y00 is enhanced by installing DER as well as in the case of PSK-Y00.
