[0052] Such as figure 1 As shown, it is a schematic diagram of an encrypted transmission method provided by an embodiment of the present invention; see figure 1 , figure 1 Include the following steps:

[0053] S101. The first terminal sends an encryption start request to the second terminal.

[0054] It should be noted that, in this embodiment, the first terminal and the second terminal may be converted to each other under one condition.

[0055] S102. The second terminal receives the encryption start request, and returns encryption response information to the first terminal.

[0056] After receiving the encryption start request, the second terminal determines whether to agree to encrypted transmission with the first terminal, and then sends the encrypted response information to the first terminal. It can be understood that the returned encrypted corresponding information includes not only the second terminal's The confirmation information may also include some communicati...

[0075] Such as figure 2 As shown, it is a quantum encryption method provided by the embodiment of the present invention. The quantum encryption method is applied in the process of quantum encryption transmission. The quantum encryption method includes: the first application layer of the first terminal obtains the first quantum from the key server The key information is sent to the first kernel, and the first quantum key information is configured to the first kernel through a preset encryption algorithm, and the first quantum key configuration information corresponding to the first kernel is updated; The key configuration information is returned to the first application layer and sent to the second application layer of the second terminal; the second application layer sends the corresponding first quantum key configuration information to the second kernel, and the corresponding The configuration information of the first quantum key is decrypted.

Abstract

The embodiment of the invention provides an encryption transmission method and a quantum encryption method. In the encryption transmission method, a first terminal and a second terminal communicate with each other to determine an encryption transmission protocol; when the quantum key is adopted to encrypt a pure genus, the quantum key is respectively acquired from the key server for encryption transmission confirmation; Encryption verification between the first terminal and the second terminal is completed by sending quantity keys to the two terminals through the key server, so that the problem that mutual encryption verification between the two terminals is intercepted is avoided, and the security of encryption verification is improved; The quantum encryption method is applied to the encryption transmission method, the quantum encryption method adopts a quantum key to encrypt and decrypt in the encryption transmission process between a first terminal and a second terminal, and adoptsthe quantum key to encrypt and decrypt, so that the decoding process of a data packet is more difficult, and the security of encryption transmission is improved.

Description

technical field [0001] The invention relates to the technical field of communication, and more specifically, to an encrypted transmission method and a quantum encryption method. Background technique [0002] Under the existing IPSEC (Internet Protocol Security) system, during the link establishment process, the key used to encrypt data will be generated later, and the key period is the time set by the user (usually more than a few hours, if The setting time is short, which will lead to frequent key generation and increase the system burden), in view of the fact that the computer capacity is becoming more and more powerful, theoretically there is a risk that the traditional encryption key will be cracked. [0003] Quantum key: Utilizing the "quantum non-cloning theorem, quantum indivisibility" feature, the key encrypts information, which is currently the only known distribution method that cannot be eavesdropped or deciphered. Combined with traditional IPSEC, it not only uti...
