Secure communication method, device and system based on quantum random number

The invention belongs to the technical field of nuclear power, and particularly relates to a secure communication method, device and system based on quantum random numbers. According to the method disclosed by the invention, an asymmetric encryption mode is applied, an encryption public key of each client side is adopted to encrypt the issued quantum key, and the quantum key is decrypted through an encryption private key of the client side, so that the quantum key does not appear in a transmission channel in a plaintext in the whole issuing and transmission process, and the quantum key cannot be transmitted in the transmission channel. The probability that the quantum key is stolen is greatly reduced, and the quantum key is absolutely random and unpredictable, so that safe encryption and decryption operation can be carried out even in an unsafe network environment. 本公开属于核电技术领域，具体涉及基于量子随机数的安全通信方法、装置及系统。本公开的方法运用非对称加密方式，采用每个客户端的加密公钥对下发的量子密钥进行加密，并通过客户端的加密私钥对量子密钥进行解密，这样，量子密钥在整个下发传输过程中均未明文出现在传递通道内，大大降低了量子密钥被窃取的概率，加
