Embodiment Construction

[0019] A safe and efficient quantum key service method, such as figure 1 shown, including the following:

[0020] According to the requirements of the application system, the proxy server applies for the quantum key from the quantum key service system; the quantum key service system applies for the quantum key from the QKD node, and encrypts the arranged quantum key data to the proxy server, and the proxy server passes the security The interface injects the quantum key into the application system.

[0021] Specifically include the following steps:

[0022] Step 1: According to the requirements of the application system, the initiator proxy server A initiates a session request to the responder proxy server B; proxy server A and proxy server B perform authentication based on the pre-shared key between them; after mutual authentication is completed, negotiate The parameters needed to apply for the quantum key (including at least the data format, group number and length of the q...

Abstract

The invention discloses a safe and high-efficient quantum key service method. The method aims at solving flexibility, safety and efficiency problems of a cross-domain service of a quantum key from a QKD network to a traditional secret communication network. A special interface is adopted to realize real-time access and adaption of the quantum key; cross-domain isolation is adopted to realize physical safety of quantum key processing; and a centralized layout and distributed encryption ferry is adopted to realize a safe and high-efficiency service of the quantum key. In the invention, through deploying a quantum key service system on a QKD node, based on the traditional secret communication network, a safe and high-efficiency quantum key service is provided for a user in an area range; and simultaneously the safety, flexibility and efficiency problems of the quantum key service are solved. Based on high safety, convenient application access and a flexible service mode, a good application prospect is possessed in fields of party, government, industrial control, finance, military and the like.

Description

technical field [0001] The invention relates to a safe and efficient quantum key service method. Background technique [0002] Quantum key distribution (QKD) is a new type of online security distribution technology for random keys. It is based on the quantum uncertainty principle and the non-cloning theorem. key distribution. QKD has significant advantages in improving the security and real-time performance of key distribution. Encouraged by relevant national industrial policies and against the background of rapid development of cyberspace security technology, the development of the quantum communication industry with QKD network deployment and fusion application system construction as the main body has entered a period of rapid development. Since the QKD network is relatively independent in terms of technical system, it is difficult to achieve the same channel transmission with the traditional secure communication network in the fiber channel, and it is difficult to secur...
