Example Embodiment

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described through specific embodiments and drawings below.

[0036] The network authentication scheme adopted by the present invention is composed of a device end (or called a device terminal, a client) and a server end (or called an authentication server). The communication link between the device side and the server side adopts asymmetric encryption algorithm for encrypted transmission, the device side uses public-key encrypted transmission, and the server side uses private-key encrypted transmission. The device side and server side should have the files shown in Table 1 below:

[0037] Table 1. Files on the device side and server side

Abstract

The invention relates to a network authentication method and system based on data link encryption transmission. The method is characterized in that the network link data are encrypted by the asymmetric algorithm and then transmitted, which avoids network monitoring and input; the network identity information is the specific device hardware and software information and has the uniqueness; a network key and the identity information are updated during starting the network authentication, in order to limit the ageing cycle of the network transmission key and the identity information; the symmetric encryption algorithm is carried out for random authentication, namely, real-time authentication, and thereby, the difficulty at breaking the data monitoring is raised, and transferring the device to other place to operate after the identity is authenticated successfully is effectively prevented. With the adoption of the method and system, the link can be effectively prevented from being monitored, and authentication files are prevented from releasing and spreading; once the authentication files are released and used and a legal user feeds back timely, a server can timely find out the device network information of a device end.

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...
