    "abstract": "Recently, Zhang, Li, and Guo have proposed a particular eavesdropping attack\n[Phys. Rev. A {\\bf 63}, 036301 (2001), quant-ph/0009042] which shows that my\nquantum key distribution protocol based on entanglement swapping [Phys. Rev. A\n{\\bf 61}, 052312 (2000), quant-ph/9911025] is insecure. However, security\nagainst this attack can be attained with a simple modification. In addition, a\nsimpler version of the protocol using four qubits is introduced.",
