Embodiment 1

[0048] This embodiment provides a handshake method based on a quantum terminal, which can be used in a handshake device. Such as figure 2 As shown, the handshake method includes the following steps:

[0049] In step S11, the first communication terminal and the second communication terminal respectively obtain security keys from the quantum terminal, generate respective master keys and required key pairs, and store the master keys in the Session object.

[0050] When the first communication terminal and the second communication terminal are respectively connected to the corresponding first quantum terminal and the second quantum terminal, the first quantum terminal and the second quantum terminal perform key negotiation to generate a shared key, and the first communication The end obtains the security key (that is, the shared key) from the first quantum terminal, and the second communication end obtains the security key (that is, the shared key) from the second quantum termi...

Embodiment 2

[0057] This embodiment provides a handshake method based on a quantum terminal, which can be used in a handshake device. Wherein, the first communication terminal is connected with the first quantum terminal, and the second communication terminal is connected with the second quantum terminal. In this embodiment, the communication protocol between the first communication terminal and the second communication terminal is selected from but not limited to Transport Layer Security (TLS for short). Such as image 3 As shown, the handshake method includes the following steps:

[0058] In step S21, the first communication terminal and the second communication terminal respectively obtain security keys from the quantum terminal, generate respective master keys and required key pairs, and store the master keys in the Session object.

[0059] The first quantum terminal and the second quantum terminal respectively generate keys, and after key negotiation, form a shared key, which is use...

Embodiment 3

[0080] This embodiment provides a handshake method based on a quantum terminal, which can be used in a handshake device. In this embodiment, the communication protocol between the first communication terminal and the second communication terminal is selected from but not limited to Transport Layer Security (Transport Layer Security, TLS for short). Such as Figure 4 As shown, the method includes the following steps:

[0081] In step S31, the first communication terminal sends a first greeting message to the second communication terminal.

[0082] The first communication terminal sends the first greeting message (ClientHello) to the second communication terminal. The ClientHello message includes the communication protocol version supported by the first communication terminal itself, the encryption algorithm suite, and the random key used when generating the master key. Number, the use of this random number can add some random factors to generate the master key, so as to ensure ...

Abstract

The invention discloses a handshake method and device based on a quantum terminal. The handshake method based on the quantum terminal comprises the following steps: a first communication terminal anda second communication terminal obtain security keys from the quantum terminal respectively, generate respective main keys and required key pairs respectively, and save the main keys in the Session objects respectively; and after the first handshake of the first communication terminal and the second communication terminal is completed, and when the handshake is carried out again, the first communication terminal and the second communication terminal obtain the main keys from the respective Session objects to generate the respective key pairs. According to the invention, the first communicationterminal and the second communication terminal obtain the security keys from the quantum terminal, and save in the Session objects after generating the main keys; and when the Session is needed for reuse, the first communication terminal and the second communication terminal obtain the respective main keys from the Session objects respectively without the communication with the quantum terminal,therefore, the load on the quantum communication line is reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a quantum terminal-based handshaking method and device. Background technique [0002] As human society enters into informatization, people communicate more and more frequently, people's demand for information is increasing day by day, and the acquisition and release of information has penetrated into everyone's daily life. But at the same time, various incidents of information leakage and illegal access to information continue to occur, which makes information security increasingly the focus of attention. [0003] The development of quantum mechanics since the 20th century has enabled human beings to study matter into the microscopic field, and discovered two major principles of quantum mechanics, namely, the principle of quantum uncertainty and the principle of quantum non-cloning. The principle of quantum indeterminacy shows that the quantum state of a position cannot b...
