Train service data processing method and system based on quantum key

Abstract

The invention provides a train service data processing method and system based on a quantum key, and the method comprises the steps: a locomotive client receives a business data processing request from a locomotive, and then calls an SATA password module to enter a business data encryption starting process; the SATA cryptographic module automatically judges whether effective static session key pairs and application key pairs exist or not, if not, entering an SATA cryptographic module self-checking mode, if yes, encrypting service data and subjecting to signature operation, wherein the encrypted first encrypted data are sent to the locomotive server side from the locomotive client side, and the locomotive server calls the quantum security service platform to decrypt the first encrypted data and returns the decrypted data ciphertext to the locomotive server, and the locomotive server correspondingly processes the business data. According to the invention, data encryption transmission of train operation production data from a train end to a business background is realized, so that comprehensive password protection is provided for locomotive operation control, state acquisition and sensitive data transmission.

Description

technical field [0001] The invention belongs to the field of quantum encryption, and in particular relates to a quantum key-based train service data processing method and system. Background technique [0002] At present, the current situation of network information security is becoming increasingly severe, and security threats are gradually shifting from destroying to stealing data. Relevant national laws and regulations are gradually improving, supervision is more stringent, and data security-related standards and management methods are being formulated. As the core technology and basic support of information security technology, cryptography is also a key technology for protecting data security. The existing cryptographic technology, along with the threat brought by the development of quantum computing, has attracted widespread attention to quantum secure communication technology and applications. Among them, quantum key distribution and quantum random number generator t...
