We present a new quantum key distribution (QKD) scheme using EPR pairs and Bell state measurement, accompanied by quantum one-way function. The security of our scheme derives from BB84 protocol, and several other features make our QKD scheme fairly suitable for QKD network designs. So we then apply a modified version of our QKD scheme to construct a QKD network, allowing secure key distribution among...
In this paper, we propose a secure user authentication protocol with nonentanglement-based QKD on jammable public channels between two parties, Alice and Bob. First, via an arbitrator (Trent), the protocol provides both quantum authentication and quantum key distribution. Second, due to the registration to the trusted third party and the initial bit string of Alice (or Bob), used for reversing the...
