Embodiment 1

[0056] figure 1 is a schematic flowchart of the method for verifying network data in Embodiment 1 of the present invention, refer to figure 1 , a method for verifying network data, comprising steps S101 to S104.

[0057] S101, generating a query request according to the data to be verified;

[0058] S102, send the query request to the DNS server, the DNS server parses the query request, obtains a data verification request, performs MD5 verification on the data verification request, generates an MD5 verification result, and generates an IPV6-compliant result according to the MD5 verification result The result of domain name resolution in the form of;

[0059] S103, receiving the domain name resolution result returned by the DNS server;

[0060] S104, calculate the local MD5 verification result, and compare and verify the domain name resolution result and the local MD5 verification result.

[0061] In this embodiment, the query request is an IPV6 domain name query request. ...

Embodiment 2

[0066] figure 2 is the structural block diagram of the network data verification device in the second embodiment of the present invention, refer to figure 2 , a network data verification device, comprising:

[0067] The request generation module is used to generate query requests according to the data to be verified;

[0068] The request sending module is used to send the query request to the DNS server, the DNS server parses the query request, obtains a data verification request, performs MD5 verification on the data verification request, generates an MD5 verification result, and checks according to MD5 As a result, a domain name resolution result in the form of IPV6 is generated;

[0069] The domain name resolution receiving module is used to receive the domain name resolution result returned by the DNS server;

[0070] The calculation and comparison module is used to calculate the local MD5 verification result, and compare and verify the domain name resolution result a...

Embodiment 3

[0073] image 3 is a schematic flowchart of the network data verification method in Embodiment 3 of the present invention, refer to image 3 , a method for verifying network data, comprising steps S201 to S205.

[0074] S201, receiving a query request sent by a client;

[0075] S202, parse the query request to obtain a data verification request;

[0076] S203, perform MD5 verification on the data verification request, and generate an MD5 verification result;

[0077] S204, generating a domain name resolution result conforming to the IPV6 format according to the MD5 verification result;

[0078] S205, the domain name resolution result is returned to the client, the client calculates the local MD5 verification result, and compares the domain name resolution result with the local MD5 verification result.

[0079] In this embodiment, step S204 specifically includes: according to the MD5 verification result, generating a domain name resolution result conforming to the IPV6 form...

Abstract

The invention discloses a network data verification method, comprising: generating a query request according to the data to be verified; sending the query request to a DNS server, and the DNS server analyzes the query request to obtain a data verification method; Verify the request, perform MD5 verification on the data verification request, generate the MD5 verification result, and generate a domain name resolution result conforming to the IPV6 form according to the MD5 verification result; receive the domain name resolution result returned by the DNS server; calculate the local MD5 Verifying the result, comparing and verifying the domain name resolution result and the local MD5 verification result. The invention also discloses a network data verification device and system. The present invention relates to the field of network security, a method, device and system for verifying network data. Compared with the data verifying in the prior art, links such as DNS query and TCP connection establishment are simplified, the interaction is simpler, the efficiency is higher, and the System consumption, providing concurrent processing capabilities.

Description

technical field [0001] The present invention relates to the field of network security, and in particular, to a method, device and system for verifying network data. Background technique [0002] In the process of Internet data transmission, it will be affected by various interferences, such as impulse interference, random noise interference and human interference, which will cause data errors. Data verification is a verification operation to ensure the integrity of the data. Usually, a specified algorithm is used to calculate a check value for the original data, and the receiver uses the same algorithm to calculate the check value once. If the check value obtained by the two calculations is the same, the data is complete. [0003] At present, the commonly used data verification method is the MD5 verification method, which checks the correctness of the data by performing a hash operation on the received transmission data. The calculated hash value is compared with the hash ...
