| Abstract: | The security of the quantum secure deterministic communication
scheme {\it Chin. Phys.} {\bf16} (2007) 2549] is reexamined. A
security loophole is pointed out. Taking advantage of this loophole,
an eavesdropper can steal all the secret messages without being
detected by an intercept-and-resend attack strategy. Furthermore, a
possible improvement on this protocol is presented. It makes the
modified protocol secure against this kind of attack. |
