Abstract

The invention discloses a method for updating and using a secret key in a power grid SSL VPN. The method conducts double network combination on a quantum secret key distribution network and a power system dispatching data network, and aims to apply an unconditionally secure quantum secret key to a power grid in a double network combination mode, and the safety of power data transmission is guaranteed. The specific method that the two networks are combined is provided, three modes that the quantum secret key is applied to the power grid SSL VPN are achieved, and specific communication processes in the network after combination are achieved. The method for updating and using the secret key in the power grid SSL VPN has the advantages of being convenient and practical, saving in cost, and meanwhile capable of enhancing the safety of transmitting data.

Description

technical field

[0001] The present invention relates to the fields of communication and quantum cryptography, in particular to a method for updating and using keys in SSL VPN of a power grid. A class of usage methods. Background technique

[0002] With the development of business, the scale of power system dispatching data network is getting larger and larger, and there are various types of data that need to be processed. Almost all provinces, cities and towns have established corresponding subnets. An effective communication mechanism is needed between subnets and between subnets and the main station to ensure data security. It not only ensures the confidentiality of information between base stations, but also ensures the isolation between different services and identity authentication between different users. According to this demand, the technology commonly used at present is virtual private network technology (VPN), which establishes virtual tunnels between base stati...
