Abstract

The invention discloses a quantum key transmission control method. The method comprises steps as follows: a sending-end service application terminal and a receiving-end service application terminal negotiate to acquire various parameters of quantum keys; the sending-end and receiving-end service application terminals send key requests to first and second quantum key management terminals respectively and acquire the quantum keys; the sending-end and receiving-end service application terminals use the quantum keys to perform encryption, decryption and the like on user services or data, so that safe communication services are provided. The invention further provides the corresponding quantum key management terminals, the corresponding service application terminals and a corresponding quantum key transmission control system. With the adoption of the method and the system, the high efficiency and the consistency of application and acquisition of the quantum keys by the service application terminals can be guaranteed, the universality is good, and the method and the system can be applied to communication processes of different service application terminals and quantum key management terminals.

Description

technical field [0001] The present invention relates to the field of quantum security communication, and in particular provides a quantum key transmission control method, system, quantum key management terminal and service application terminal. Background technique [0002] With the rapid development of network technology, a large amount of sensitive information needs to be transmitted through the network, and people need to protect sensitive information from being lost or attacked. Encryption is one of the important means to ensure information security. For classical communication, the most commonly used encryption technology currently uses complex mathematical algorithms to change the original information, such as AES, 3DES, RSA, MD5, SHA-1 and so on. [0003] The existing classical encryption system is based on computational complexity. With the advancement of mathematics and the continuous improvement of computer speed, it may be deciphered, but it is not absolutely rel...
