Chinese Scientists Integrate Quantum Technology into E-commerce
Beijing, The Gulf Observer: Chinese scientists have achieved a groundbreaking milestone by devising an e-commerce strategy that facilitated the world’s inaugural five-user online trading experience through the integration of quantum technology. This innovation addresses the existing vulnerability of e-commerce messages, safeguarded by conventional encryption algorithms, to potential hacking by advanced quantum computing systems. The development marks a significant stride in fortifying the security infrastructure of online transactions and exemplifies China’s pioneering efforts in applying quantum technology to real-world applications.
Therefore, some cryptologists have tried to use quantum entanglement to securely distribute unhackable quantum states among multiple parties to guard against identity theft and payment fraud.
However, a feasible quantum algorithm that prevents message senders from denying offers they have already made in transactions has not been developed previously.
Researchers at Nanjing University and Renmin University of China created an e-commerce protocol based on a new quantum digital signature (QDS) that generates correlated bit strings among multiple remote parties for signatures via quantum law.
They proposed a QDS approach that combined quantum secret sharing and one-time universal hashing to ensure transaction integrity, authenticity, and, in particular, non-repudiation.
In an experiment, the team demonstrated a five-user quantum network using the protocol, according to the study published on Saturday in the journal Science Advances.
The quantum network can ensure that contract signing and payments are executed fast and accurately, eliminating the need for a trusted third party to be identified in advance.
“Our work contributes to the further development of e-commerce in the quantum era by providing a practical and efficient solution with enhanced security,” said Yin Hualei, an associate professor from Renmin University of China.
