Abstract
Description
Technical Field
[0001] This invention relates to the technical field of charging pile information security protection system, specifically to a charging pile information security protection system based on multi-copy verification. Background Technology
[0002] With the increasing popularity of new energy vehicles, more and more charging stations are being deployed in parking lots and other areas. However, because charging stations are mostly deployed in public areas, they are vulnerable to cyberattacks and tampering with relevant critical data. This has a significant impact on the daily use of charging stations and charging safety.
[0003] To address the above issues, most solutions on the market are based on information encryption. However, as embedded devices, charging piles have limited computing power and cannot perform efficient and complex encryption calculations on data. Furthermore, complex encryption algorithms result in insufficient computing power for the charging pile operation and management platform, limiting the number of devices the platform can accommodate and increasing the production and maintenance costs of charging piles.
[0004] To address the challenges posed by the low computing power and limited storage space of charging piles, an information security protection system specifically designed for charging piles urgently needs to be developed. Summary of the Invention
[0005] The technical problem to be solved by this invention is to overcome the above-mentioned technical defects and provide an effective solution to information security problems caused by network attacks, etc. At the same time, this invention is a charging pile information security protection system based on multi-copy verification with low implementation cost and high reliability. This invention is compatible with information encryption-based security protection methods. On the basis of information encryption, it can use multiple copies for information verification to further enhance security, prevent tampering, and prevent repudiation.
[0006] To address the aforementioned technical problems, the present invention provides a charging pile information security protection system based on multi-copy verification, comprising a charging pile operation management platform and a charging pile cluster. The charging pile cluster consists of multiple charging piles deployed in adjacent areas. Each charging pile comprises a main communication device, an auxiliary communication module, a computing module, and a storage module. The main communication device communicates with the charging pile operation management platform. When the main communication device uploads complete information to the charging pile operation platform, the auxiliary communication module simultaneously broadcasts key information to surrounding charging piles. Upon receiving this key information, the surrounding charging piles store it in their local storage module. The charging pile operation management platform performs legal and reliable verification on the information from the main communication device. Adjacent charging piles broadcast data verification requests to their surroundings via the auxiliary communication module. Upon receiving the data verification request, the surrounding charging piles send the stored key information corresponding to the charging pile to the charging pile operation management platform for verification. The charging pile operation management platform verifies the multiple data copies received.
[0007] As an improvement, the main communication device consists of 2 / 3 / 4 / 5G / wifi modules.
[0008] As an improvement, the auxiliary communication module is composed of Zigbee / Bluetooth.
[0009] As an improvement, the charging pile operation management platform identifies data as abnormal or suspicious and sends a retransmission request to the suspicious charging pile. After receiving the retransmission request, the charging pile retransmits the data and broadcasts a data verification request to the surrounding area.
[0010] As an improvement, when the charging pile operation management platform fails to verify multiple sets of data, it identifies the corresponding charging pile as faulty, marks it, and notifies it. Based on the results of the charging pile operation management platform's verification of multiple sets of data, the cause of the charging pile fault can be further inferred.
[0011] As an improvement, if the charging pile malfunctions and information is lost due to failure to upload to the charging pile operation platform, a data verification request can be actively broadcast to the surrounding area through the auxiliary communication module.
[0012] As an improvement, the storage module stores key information broadcast from surrounding charging piles by entry. Key information entries include, but are not limited to, charging pile ID, charging gun ID, charging gun power information, and charging gun billing information. When new key information is received from surrounding charging piles, the information stored in the original entries will be overwritten.
[0013] As an improvement, the charging pile operation management platform maintains the neighbor relationship between the charging pile and surrounding charging piles in real time. If the charging pile can receive broadcast information from surrounding charging piles, a neighbor relationship exists. The neighbor relationship can be actively reported to the charging pile operation management platform or the charging pile operation management platform can send a request to the charging pile for query. When the charging pile operation management platform receives multiple copies of data, if the data comes from a charging pile that does not have a neighbor relationship, this copy will not participate in the verification.
[0014] The advantages of this invention compared to existing technologies are as follows: The charging pile operation management platform verifies the rationality and legality of data. For data deemed abnormal, it compares and verifies the data with the copy data stored in surrounding charging piles to identify information security issues. The data stored in surrounding charging piles is transmitted wirelessly, making it difficult to simultaneously launch a network attack on all surrounding charging piles within the wireless broadcast area and tamper with all copy data. This enhances the security protection capabilities of the surrounding charging pile copy data. The copy data can be used for data recovery, giving the charging piles a certain degree of fault tolerance. Each charging pile only maintains a few key pieces of information from surrounding charging piles, meeting the characteristics of small storage space for edge devices such as charging piles. It does not require complex encryption algorithms, meeting the low computing power requirements of edge devices such as charging piles. This invention can effectively solve information security problems caused by network attacks. Furthermore, this invention has low implementation cost, high reliability, and is suitable for clustered low-performance embedded devices such as charging piles. This invention is compatible with information encryption-based security protection methods and can further enhance security by using multiple copies for information verification on the basis of information encryption.

[0015] Figure 1 It consists of system hardware modules.
[0016] Figure 2 This is a system diagram.
[0017] Figure 3 This is a system flowchart. Detailed Implementation
[0018] The present invention will now be described in further detail with reference to the accompanying drawings.
[0019] Combined with appendix Figure 1-3 As shown, a charging pile information security protection system based on multi-copy verification includes a charging pile operation management platform and a charging pile cluster. The charging pile cluster consists of multiple charging piles deployed in adjacent areas. Each charging pile consists of a main communication device, an auxiliary communication module, a computing module, and a storage module. The main communication device communicates with the charging pile operation management platform. When the main communication device uploads complete information to the charging pile operation platform, the auxiliary communication module simultaneously broadcasts key information to surrounding charging piles. After receiving this key information, the surrounding charging piles save it as a copy in their local storage module. The charging pile operation management platform performs legal and reliable verification on the information from the main communication device. Adjacent charging piles broadcast data verification requests to their surroundings through the auxiliary communication module. After receiving the data verification request, the surrounding charging piles send the stored key information corresponding to the charging pile to the charging pile operation management platform for verification. The charging pile operation management platform verifies the multiple data copies received.
[0020] The main communication device consists of 2G / 3G / 4G / 5G / Wi-Fi modules, and the auxiliary communication module consists of Zigbee / Bluetooth. The charging pile operation management platform identifies data as abnormal or suspicious and sends a retransmission request to the suspicious charging pile. After receiving the retransmission request, the charging pile retransmits the data and simultaneously broadcasts a data verification request to the surrounding area. After receiving the data verification request, the surrounding charging piles send the stored key information corresponding to the suspicious charging pile to the charging pile operation management platform. If the charging pile operation management platform fails to verify multiple data sets, it identifies the corresponding charging pile as faulty, marks it, and notifies the user.
[0021] When a charging pile malfunctions and its information is lost due to failure to upload to the charging pile operation platform, it can proactively broadcast a data verification request to surrounding charging piles via an auxiliary communication module. Upon receiving the data verification request, surrounding charging piles will send the stored key information corresponding to the lost charging pile to the charging pile operation management platform. The charging pile operation management platform will verify multiple data copies. If verification fails, the corresponding charging pile is considered to be malfunctioning, and the lost data cannot be recovered. If verification is successful, the corresponding copy of the data will be adopted and used by the charging pile operation management platform.
[0022] The charging pile operation management platform maintains the neighbor relationship between the charging pile and the surrounding charging piles in real time. If the charging pile can receive the broadcast information of the surrounding charging piles, a neighbor relationship exists. The neighbor relationship can be actively reported to the charging pile operation management platform or the charging pile operation management platform can send a request to the charging pile for query. When the charging pile operation management platform receives multiple copies of data, if the data comes from a charging pile that does not have a neighbor relationship, this copy will not participate in the verification.
[0023] Take the system consisting of three charging piles (A, B, and C) and a charging pile operation and management platform as an example.
[0024] like Figure 2 As shown, under normal main communication conditions, each charging pile transmits information to the operation management platform through its main communication module. This information includes, but is not limited to: charging pile ID, current current, current voltage, current billing information, status information of the vehicle being charged, and subsequent power supply demand information. Key information is broadcast through the auxiliary communication module, including, but not limited to: charging pile ID, charging gun ID, charging gun power information, and current billing information of the charging gun. When new key information is received from surrounding charging piles, the original information will be overwritten.
[0025] like Figure 3The diagram shows the system flowchart. After a charging pile generates data, it uploads the complete data to the charging pile operation management platform and broadcasts key data to surrounding charging piles. Upon receiving the broadcast, surrounding charging piles save the key data as a copy, overwriting the original copy. The charging pile operation management platform verifies the data's validity and legitimacy. If verification passes, the data is saved, processed, and sent back. If verification fails, the platform requests the suspicious charging pile to retransmit, and simultaneously broadcasts a verification request message to surrounding charging piles. Upon receiving this message, surrounding charging piles upload their stored copy data to the platform for verification. The platform receives multiple copies of charging pile data and filters them. If the copy data does not originate from a nearby charging pile, it will not be used for verification. If multiple data verifications fail, the platform considers the corresponding charging pile abnormal, marks it, and notifies relevant maintenance personnel. Based on the results of multiple data verifications by the charging pile operation management platform, the cause of the charging pile anomaly can be further inferred. If the data reported by the suspicious charging pile is consistent with the copy data, but neither is reasonable or legal, it may be a hardware or software failure of the suspicious charging pile. If the copy data is consistent, but the data reported by the suspicious charging pile is inconsistent with the copy data, it may be a main communication failure of the suspicious charging pile, posing a risk to information security. If the copy data is inconsistent, it may be a system failure of the charging pile cluster, not just a single point of failure of the suspicious charging pile.
[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
