Quantum Entanglement Establishment between two Strangers
  This paper presents the first quantum entanglement establishment scheme for strangers who neither pre-share any secret nor have any authenticated classical channel between them. The proposed protocol requires only the help of two almost dishonest third parties (TPs) to achieve the goal. The security analyses show that the proposed protocol is secure against not only an external eavesdropper's attack, but also the TP's attack.
