Abstract

The present invention relates to the field of communication technology, in particular to a power service encryption method and device based on a quantum satellite key network, wherein the method includes obtaining an encryption request for power service data; extracting at least two quantum keys from a quantum key buffer; Quantum keys generated by at least two terminals are stored in the key buffer, and the extracted quantum keys are generated by at least two terminals; the power service data is encrypted according to the extracted quantum keys. By using quantum keys generated by different terminals to encrypt power business data, the security of power business data transmission can be improved due to the characteristics of quantum keys themselves and the combination of quantum keys generated by different terminals; The speed and continuity of the key are different, and the quantum key buffer is used to store the quantum key, which provides conditions for the combination of quantum keys generated by different terminals to encrypt power service data.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a power service encryption method and device based on a quantum satellite key network. Background technique [0002] To ensure the security of data transmission, the data is encrypted before data transmission between terminals. Among them, the data transmitted by electronic equipment is collectively referred to as power business data. The power business data mentioned are data generated by video conferencing, administrative telephone calls, dispatching, and power trading. [0003] In the prior art, when encrypting power service data, an asymmetric cipher is generally used to encrypt the data. For example, the asymmetric cryptographic system represented by the RSA algorithm uses two different keys, one as a public key and the other as a secret key; anyone can use the public key to encrypt the plaintext message to be transmitted, and use The secret key decrypts the encryp...
