A network authentication method and system based on data link encrypted transmission

Abstract

The invention relates to a network authentication method and system based on data link encrypted transmission. The network link data is encrypted and transmitted using an asymmetric algorithm to prevent network monitoring and injection. The network identity information is specific device hardware and software information, which is unique. During the start-up process of network authentication, the network key and identity information will be updated to limit the time limit for network transmission key and identity information. In addition, random authentication through symmetric encryption algorithm, that is, network real-time authentication, increases the difficulty of data being monitored and cracked, and effectively prevents the device from being transferred to other places for operation after successful identity authentication. The present invention can effectively prevent the link from being monitored, and prevent authentication files from being leaked and used; if the authentication file is leaked and used, the server can timely discover the device network information of the device terminal through timely feedback from legal users.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a network authentication method and system based on data link encrypted transmission. Background technique [0002] With the development of computer software and hardware, in order to better protect the intellectual property rights of computer software and hardware products, manufacturers often use various encryption and authentication technologies to ensure that the products are used legally, avoid piracy and hotlinking, and effectively protect the legitimate rights of developers. rights and interests. The current popular software and hardware protection methods are as follows: [0003] Serial number protection: When the user wants to obtain the right to use a certain software, he needs to register relevant information with the relevant software company, and enter the corresponding information in the software according to a series of registration steps, such as...

AI Technical Summary

Problems solved by technology

[0007] 1. The storage and use of the serial number or registration file itself is not safe, and the authentication information is stored on the same storage medium as the relevant software, which is easy to be stolen by hackers

Both the serial number and the registration file are local authentication methods, and are easy to be cracked and copied through data analysis methods such as memory images

[0008] 2. The algorithm of the software dog has been fixed after leaving the factory, and there are situations such as theft and loss. The encrypted data is easy to be intercepted locally, and the memory image is cracked, etc.
