Data access method on the basis of IP protection

Abstract

The present invention relates to a data access method on the basis of IP protection including the steps as follows: inspecting whether times of inconsistence of designated field content in a received network data packet arrives to a preset threshold value or not so as to obtain a judging result; locking the IP transmitting the network data packet when the judging result exceeds the preset threshold value, and no more processing the network data packet transmitted by the IP in the schedule time; unlocking the IP when the schedule time ends and the IP transmits the correct packet. The method can avoid that a malicious client transmits some probe packets so as to obtain the relevant information of a server, and can reduce the attack speed on the basis of IP.

Description

technical field [0001] The invention relates to a method for a server to deal with client data access, specifically an IP-protected data access method suitable for embedded applications, and belongs to the technical field of data communication. Background technique [0002] When an embedded device provides a server application, since the CPU load capacity of the embedded device is limited, the resources available for client access are also limited. As more and more clients are connected to the embedded device, the response speed of the CPU of the embedded device will decrease significantly, and the response to the client's request will become slower and slower. If a new CPU is replaced, the hardware cost will be increased, and it is unrealistic to replace the CPU for a device that has already been put into production. The CPU response of the embedded device is too slow and the customer experience is not good. At the same time, if there is a malicious client constantly send...

Problems solved by technology

If a new CPU is replaced, the hardware cost will be increased, and it is unrealistic to replace the CPU for a device that has already been put into production. The CPU response of embedded devices is too slow and the customer experience is not good

At the same time, if there is a malicious client constantly sending IP data packets to detect the information of the embedded device, then because the embedded device needs to process too many data packets, it will also occupy a large amount of CPU running time, which will cause other Tasks cannot update information, and equipment alarms, power information, etc. cannot be updated in real time, which will also lead to poor customer experience
