测量设备无关的可认证量子安全直接通信协议
Measurement-Device-Independent Certified Quantum Secure Direct Communication Protocol
摘要
Abstract
Quantum Secure Direct Communication(QSDC)protocol ensures the confidentiality of transmitted information,while such protocols heavily depend on high-precision devices,which leads to increased resource consumption costs.This study proposes a measurement-device-independent QSDC protocol with identity authentication functionality.In this protocol,the communicating parties achieve bidirectional identity authentication and secure communication with the assistance of a semi-honest third party,who is responsible for the preparation of quantum states and all measurement tasks.The communicating parties only need to perform specific unitary operations on the quantum states based on their private information,without relying on measurement devices or possessing the ability to generate quantum states.Security analysis shows that the protocol can resist various common attacks,including intercept-measure-resend attacks,fake-particle attacks,double-CNOT attacks,and entangled measurement attacks.Compared with other authenticated QSDC protocols,the proposed protocol features a high quantum bit rate and does not require shared key assistance,thereby exhibiting strong practicality.Finally,to verify the practical feasibility of the protocol,circuit simulation is conducted on the IBM Quantum Platform,and the results confirm the protocol's correctness and effectiveness.关键词
