Problems solved by technology

However, the capacity of quantum channels in literature [2] and literature [4] is only 1 bit per round of covert communication, which is obviously too small for efficient covert communication
Although the capacity of the quantum channel in [6] has been increased to 4 bits, it is still not large enough

[0147] 1. Application example of quantum steganography protocol

[0148] An example is used to further explain the quantum steganography protocol of the present invention. Suppose the secret message Alice wants to send to Bob is 100, and the sequence of messages generated by Alice is ... 000 100 …001 101 …010 110 …011 111 …100 000 …101 001 …110 010 …111 011 …(Since the two U k Represents 6-bit information, and the information is divided by every 6 bits). Assume 000 100 、001 101 、010 110 、011 111 、100 000 、101 001 、110 010 、111 011 The group numbers in the information sequence are No. 7, 10, 13, 16, 20, 25, 28 and 32, respectively. In S4, Alice sets m=7, 10, 13, 16, 20, 25, 28, and 32 to meet the consistency of the encoding shown in Table 1. If m=7, A' 6 B' 6 C' 6 will be |Ψ 1 >, A' 7 B' 7 C' 7 will be |Ψ 5 >. Correspondingly, the secret message 100 passes through A' 7 B' 7 C' 7 with A' 8 B' 8 C' 8 The entanglement exchange between them is trans...

Abstract

According to quantum steganography, the classical steganography and quantum secure communication are combined together, and the quantum steganography is popularized in the field of quanta. The quantum steganography aims to realize secret transmission of classified information by utilizing a quantum hidden channel. The invention provides a quantum steganography protocol based on gigahertz (GHZ) state dense coding and entanglement exchange. A hyper-quantum channel of the protocol is formed by establishing the hidden channel on a quantum secure direct communication (QSDC) protocol. The classified information is transmitted by combining the GHZ state dense coding and GHZ state entanglement exchange based on the original QSDC. The capacity of the hyper-quantum channel of the protocol reaches 6-bit per round in covert communication. In addition, the protocol has high imperceptibility and high safety.

Description

technical field [0001] The invention relates to the field of quantum security communication. The present invention designs a quantum steganographic protocol based on GHZ state dense coding and entanglement exchange, and establishes a hidden channel by combining GHZ state dense coding and GHZ state entanglement exchange to secretly transmit secret messages. Background technique [0002] Quantum steganography combines classical steganography and quantum secure communication, and is the promotion of classical steganography in the quantum field. The goal of quantum steganography is to use quantum hidden channels to realize the secret transmission of secret messages. Quantum steganography has important applications in high-security secret communication, quantum identity authentication, and providing alternative classical channels for quantum secure communication. Quantum steganography has become a new research branch in the field of quantum secure communication, and has attract...
