    "abstract": "In this paper we investigate the security of a quantum cryptographic scheme\nwhich utilizes balanced homodyne detection and weak coherent pulse (WCP). The\nperformance of the system is mainly characterized by the intensity of the WCP\nand postselected threshold. Two of the simplest intercept/resend eavesdropping\nattacks are analyzed. The secure key gain for a given loss is also discussed in\nterms of the pulse intensity and threshold.",
