Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0040] The embodiment of the present application discloses a security protection method for electricity consumption information collection based on quantum keys. The key ciphertext issued by the key online distribution device is received by the electricity consumption information collection terminal. The ciphertext obtained by encrypting the decryption key with the key; the electricity consumption information collection terminal uses the quantum key to decrypt the ciphertext of the k...

Abstract

The present invention provides a quantum encryption-based electricity use information acquisition security protection method and system. The method includes the following steps that: an electricity use information acquisition end receives a key ciphertext distributed by a key online distribution device, wherein the key ciphertext is a ciphertext which is obtained by encrypting a decryption key through using a quantum key; and the electricity use information acquisition end decrypts the key ciphertext through using the quantum key so as to obtain the decryption key. With the method of the present invention adopted, the real-time performance of key transmission is improved, and the security of the update of the decryption key is guaranteed.

Description

technical field [0001] The present application relates to the field of communications, and in particular to a quantum encryption-based security protection method and system for electricity consumption information collection. Background technique [0002] In the information age, the security and confidentiality of electricity consumption information has gradually been paid attention to. In order to ensure the safe transmission of electricity consumption information, in the existing electricity consumption information collection system, an encryption key and a decryption key are respectively distributed to the electricity consumption information sending end and the electricity consumption information collection end, and the electricity consumption information sending end uses the encryption key The electricity consumption information is encrypted, the encrypted electricity consumption information is transmitted on the network, and the electricity consumption information collec...
