Abstract
With the acceleration of the construction of quantum communication
networks, scholars have proposed different quantum communication protocols
for different application scenarios. However, few scholars pay attention to the risk
assessment process before communication. In this paper, we propose a novel
quantum risk assessment model based on quantum teleportation technology with
two three-qubit GHZ states. Only by using Bell states measurements (BSMs) and
two-qubit projective measurements (PJMs), the communicators can recovery any
arbitrary two-qubit state. This protocol can transmit two-dimension risk assessment factors with better security performance. On the one hand, more sufficient
evaluation factors allow the two communicating parties to more objectively evaluate the risk level of communication with the other party, and on the other hand, it
also improves the qubit efficiency of the protocol. Moreover, we introduce the
third party in this scheme can be semi-trusted, which must be full-trusted in
our previous work. This change can reduce the dependence of the communication
parties on the third-party organization and improve the privacy of communication.
The security analysis shows that this scheme can resist internal and external
attacks, and the quantum circuit diagrams also prove that our protocol is physically easier to implement.
