Safety verification method based on session connection and network device

Abstract

The present invention relates to a safety verification method based on session connection and a network device. The method comprises the steps of: generating first return information according to a session connection establishing instruction sent by a client; generating first combination information according to the first return information and first pre-stored passwords; according to the first combination information, combining a preset algorithm to calculate and obtain first verification information; determining whether second verification information generated by the client according to thefirst return information is matched with the first verification information or not; and if the second verification information generated by the client according to the first return information is matched with the first verification information, sending session connection establishing success information, or else, sending session connection establishing failure information. The safety verificationmethod based on session connection and the network device can perform effective verification that whether an identity of the client is valid or not in the session connection so that it is effectivelyavoided that invalid clients without built-in first pre-stored passwords establish session connection with the network device by means of modes such as network attack, identity disguising and the like, and the safety is high.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of information security verification, and in particular, relate to a session connection-based security verification method and network equipment. Background technique [0002] In the process of technological evolution towards smart home and Industry 4.0, more and more home appliances and industrial equipment are required to become network equipment with interconnection functions, such as refrigerators, air conditioners, printers, etc. Most of the network devices that implement the interconnection function use the TCP / IP communication protocol, which makes it easy for the client and network devices based on this communication protocol to communicate with each other. [0003] For example, when a network printer is running in a network environment, it can only establish a session (Session Connection) connection with one client. If a client running intelligent printing control software ...

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that the following problems exist in the prior art: due to the high openness of the TCP / IP communication protocol, there are relatively large potential safety hazards, such as network attacks, client requests to connect with disguised identities, etc.
