  Abstract

We propose a quantum entity authentication protocol that allows communication members to authenticate each other without third parties. Existing authentication protocols perform mutual object authentication under the control of a trusted third party for security and efficiency reasons. However, it is challenging to implement a trusted third party, and even if such a third party is implemented, there is always a risk that the trusted third party becomes a malicious node during the protocol execution and steals authentication keys of communication members. The protocol proposed in this paper is entirely safe from insider attacks by third parties because it allows mutual authentication between communication members without a third party by using remote Bell state preparation scheme. In addition, because the proposed protocol uses only two Bell states ｜Φ±AB that can be generated and measured by linear optics, the advantage is that it can be easily implemented in real hardware.
