Quantum asymmetric cryptography with symmetric keys
Fei Gao, Qiao-Yan Wen, Su-Juan Qin +1
Based on quantum encryption, we present a new idea for quantum public-key cryptography (QPKC) and construct a whole theoretical framework of a QPKC system. We show that the quantum…
Revisiting the security of quantum dialogue and bidirectional quantum secure direct communication
Fei Gao, Fen-Zhuo Guo, Qiao-Yan Wen +1
From the perspective of information theory and cryptography, we analyze the security of two quantum dialogue protocols and a bidirectional quantum secure direct communication (QSDC…
Cryptanalysis of the Hillery-Buzek-Berthiaume quantum secret-sharing protocol
Su-Juan Qin, Fei Gao, Qiao-Yan Wen +1
The participant attack is the most serious threat for quantum secret-sharing protocols. We present a method to analyze the security of quantum secret-sharing protocols against this…
Consistency of shared reference frames should be reexamined
Fei Gao, Fen-Zhuo Guo, Qiao-Yan Wen +1
In a recent Letter [G. Chiribella et al., Phys. Rev. Lett. 98, 120501 (2007)], four protocols were proposed to secretly transmit a reference frame. Here We point out that in these…
