Secure transmission device for calculating checksum according to classification

Abstract

The invention discloses a secure transmission device for calculating checksum according to classification, which comprises the following steps: S1, before use, directly connecting Ethernet ports P0 of a secure transmission device STD-C and a secure transmission device STD-S to a management platform, wherein the Ethernet ports P0 adopt predefined management IP addresses and ports, and an administrator sends a management command; and when the Ethernet port P0s receive a configuration message in an agreed format sent by the administrator, carrying out configuration. According to the secure transmission device for calculating the checksum according to the classification, the huge cost caused by adding a special high-performance firewall or introducing a large-scale router and increasing a large number of secure operation and maintenance personnel is overcome. According to the method and the system, the security can be outsourced to an enterprise with unique technology and capability as an independent service to ensure the security of a complex network of the enterprise, so that the risk of huge loss caused by attack of the enterprise is reduced at reasonable cost.

Description

technical field [0001] The invention relates to the technical fields of embedded equipment and communication, in particular to a secure transmission device for calculating checksums by classification. Background technique [0002] With the evolution of the market and the advancement of technology, the concept of client and server has become more and more general, requesting services and responding to services. This mechanism is used in many occasions. Of course, as the data becomes more and more important, the request and response mechanism is subject to more and more attacks. [0003] The most important attacks are: 1) Identity forgery attacks, for example, forging the identity of a mobile phone / account, logging in to the system, thereby stealing user money or committing fraud; 2) Illegal access attacks, for example, using special equipment to On the dedicated line link, introduce illegal equipment, attack large enterprises and implant Trojan horses, and then blackmail; 3)...

AI Technical Summary

Problems solved by technology

At present, large-scale routers or firewalls can solve the problem of internalization of clients and servers, but few of them can solve the problems of identity forgery attacks or illegal access attacks in a targeted manner. They simply encrypt data or use VPN channels

However, many simple service programs often do not restrict this. They are the biggest source of vulnerabilities in the system, and they are also the points that attackers hope to break through.

[0007] In short, the technical personnel of enterprises and institutions lack theoretical training and experience in dealing with system attacks. Even if there are a large number of viruses and Trojan horses in various systems, the system is being accessed and logged in maliciously, and important data of the enterprise is maliciously tampered with, they are at a loss. ignorance
