Electric power communication method and device

Abstract

The invention discloses an electric power communication method and device. The method comprises the following steps that cache servers are arranged in different levels of safety operation areas, and each server in the safety operation areas is connected to the corresponding cache servers; USB (Universal Serial Bus) ports of the server and the cache server are connected to an internal security encryption chip for encryption, and a BIOS (Basic Input Output System) is arranged, so that a system is only started from the security encryption chip at the appointed USB port; the server sets authorization for a user terminal according to the user type; a USB port of the user terminal is connected to the internal security encryption chip for encryption, and the BIOS is arranged, so that the system is only started from the security encryption chip at the appointed USB port; when the server detects an access request of a user, the server carries out user authentication; after the authentication is successful, the server carries out access, search and change on data according to instructions sent by the user terminal; and the data is stored into the cache server and is sorted in the cache server according to the addressed times. The method and the device are used for realizing the secure transmission of electric power data, are good in universality and are suitable for occasions with higher requirements for data security of electric power departments.

Description

technical field [0001] The invention relates to the field of computer information security, in particular to an electric power communication method and device. Background technique [0002] The traditional technical solutions to realize computer information security are mainly divided into two categories: one is software technical solutions. This is the most widely used technology at present, using security protection software to achieve computer information security. This technical solution has the advantages of low cost and flexible development, but there are also some shortcomings: (1) After the system is reinstalled, the software needs to be reinstalled; (2) ) The software is easy to be uninstalled, causing the computer to be in an unprotected state; (3) There are loopholes in the software, Trojan horses and viruses will attack the security protection software, stop the protection process, and make the security protection invalid. The other type is hardware technology s...

Problems solved by technology

This is the most widely used technology at present, using security protection software to achieve computer information security. This technical solution has the advantages of low cost and flexible development, but there are also some shortcomings: (1) After the system is reinstalled, the software needs to be reinstalled; (2) ) The software is easy to be uninstalled, causing the computer to be in an unprotected state; (3) There are loopholes in the software, Trojan horses and viruses will attack the security protection software, stop the protection process, and make the security protection invalid

The other type is hardware technology solutions, such as hard disks with encryption chips and secure U disks. This solution has the advantages of high security and difficulty in cracking, but there are also some shortcomings: high hardware cost, poor compatibility, and poor versatility

[0005] The above two methods need to use special information security equipment for information security control, the hardware cost is high, and the compatibility and versatility are poor
