Description

Automatic authentication method and system based on WIFI broadcast
Technical Field
The invention belongs to the field of security authentication, and particularly provides an automatic authentication method and system based on WIFI broadcasting.
Background
With the continuous research and development and popularization of new energy automobiles, more and more users have new energy automobiles, and the construction of matched charging and replacing facilities is more and more perfect. In order to prevent the charging and replacing facility from being illegally stolen by others, the charging and replacing facility needs to authenticate the new energy automobile. The authentication method of the charging pile on the electric automobile in the current market mainly comprises the following steps: physical lock, RFID card swiping, APP scanning/APP map clicking, WIFI communication authentication, fingerprint identification, iris identification and the like.
The WIFI communication authentication mainly comprises the steps that WIFI communication is established between the electric automobile and the charging pile, then the electric automobile sends an authentication request to the charging pile through the WIFI communication, the charging pile receives the authentication request of the electric automobile through the WIFI communication, and the charging pile carries out charging authorization on the electric automobile after the authentication is passed. The step of establishing WIFI communication comprises the following steps: 1. a WIFI client on the electric automobile sends a WIFI detection request; 2. a WIFI server on the charging pile receives a WIFI detection request and sends a WIFI detection response; 3, the WIFI client sends a WIFI authentication request; the WIFI server receives the WIFI authentication request and sends a WIFI authentication response; 5, the WIFI client sends a WIFI connection request; and 6, the WIFI server receives the WIFI connection request and sends a WIFI connection response.
Therefore, the WIFI communication authentication not only needs to process a complex WIFI connection interaction process, but also needs to inject related information such as SSID (service set identifier) and Password used for WIFI connection in advance to ensure that the WIFI connection between the electric automobile and the charging pile is successfully carried out, and then a specific authentication program can be executed. Since the electric vehicle and the charging pile acquire information (such as SSID and Password) of each other through wireless networking in most cases, network signals cannot be received when the charging pile and the electric vehicle are in an underground garage. Although the charging pile can be directly networked in an underground garage through a technical means (such as a wired network), it is difficult to technically ensure that the electric vehicle can also be networked at the moment, so that the vehicle cannot acquire related information (such as SSID (service set identifier) required by WIFI connection in real time at the moment, and normal authentication information interaction cannot be performed between the electric vehicle and the pile, so that power-up authorization cannot be performed in real time under the condition.

Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. For example, although the description describes the automatic authentication method based on WIFI broadcast in the present invention by taking the authentication of the charging pile to the electric vehicle as an example, it is obvious that the method of the present invention can also be used in other security authentication occasions, such as the authentication of the garage door to the vehicle, and those skilled in the art can make appropriate adjustments to the method of the present invention according to actual needs, and the adjusted scheme still falls within the protection scope of the present invention.
In addition, although the WIFI client on the electric vehicle sends the WIFI Probe Request (WIFI Probe Request) with the authentication Request information attached to the WIFI server on the charging pile described in the present application, this mode is not invariable, the WIFI client may be set on the charging pile, the WIFI server is set on the electric vehicle, the WIFI server on the electric vehicle sends the Beacon Frame (Beacon Frame) with the authentication Request information attached to the WIFI client on the charging pile, and the charging pile analyzes the authentication Request information attached to the Beacon Frame after receiving the Beacon Frame, and then performs the matching and determining operation. Such variations are not to be regarded as a departure from the basic principles of the invention and are intended to be included within the scope of the invention.
The automatic authentication system based on the WIFI broadcast comprises a first WIFI device arranged on a first target, a second WIFI device arranged on a second target and a control module. The first WIFI device sends a WIFI broadcast attached with authentication request information, and the second WIFI device receives the WIFI broadcast and the authentication request information. Depending on the content of the WIFI broadcast (i.e. in particular the WIFI probe request or the beacon frame), the first WIFI device may be a WIFI client (sending the WIFI probe request) or may be a WIFI server (sending the beacon frame). Preferably, the first object is an object to be charged with electricity, such as an electric device such as an electric automobile, an electric bicycle, or an electric motorcycle. More preferably, the first object is an electric vehicle. Or those skilled in the art may select other facilities as the first target according to the needs, such as a mobile phone often used with an electric vehicle, a car key, and other mobile terminals. Similarly, the second WIFI device may be a WIFI server (receiving a WIFI probe request) or a WIFI client (receiving a beacon frame) according to the content of the received WIFI broadcast. Preferably, the second object is a charging and replacement facility, such as a dc charging pile, an ac charging pile, a dc charger, an ac charger, a mobile charging vehicle, a mobile replacement vehicle or a replacement station. More preferably, the second object is a charging pile (a direct current charging pile, an alternating current charging pile or an alternating current and direct current charging pile). Or those skilled in the art can select other facilities as a second target according to needs, for example, an upper computer for performing unified management on a plurality of charging piles, and the like. Control module both can set up on filling electric pile, also can set up in the remote end that can communicate with filling electric pile, for example on backend server or the high in the clouds server. Also, the control module may be implemented as part of an existing system in a physical form, or may be provided as a separate dedicated module or device. Such variations are not to be regarded as a departure from the basic principles and scope of the invention.
Further, a WIFI client on the electric automobile can send authentication request information through a WIFI detection request; the WIFI server on the charging pile can receive the WIFI detection request and the authentication request information which are sent together. Alternatively, the WIFI server on the electric vehicle can send the authentication request information through the beacon frame; and the WIFI client on the charging pile can receive the beacon frame and the authentication request information which are sent together. The control module can match the received authentication request information with prestored legal authentication information and judge whether the charging pile should pass the authentication request of the electric automobile according to the matching result.
Furthermore, when the received authentication request information is matched with at least one of the pre-stored legal authentication information, the control module enables the charging pile to pass the authentication request of the electric vehicle; and when the received authentication request information is not matched with the pre-stored legal authentication information, the control module enables the charging pile to reject the authentication request of the electric automobile.
As a supplementary explanation and a preposition scheme of the invention, the WIFI client and/or the WIFI server may be activated when the charging gun on the charging post is inserted into the charging port of the electric vehicle and/or when the charging gun is pulled out of the charging post. Of course, those skilled in the art may select other activation timings and activation modes as needed, or set the color of the WIFI client and the WIFI server to remain activated.
The automatic authentication method based on the WIFI broadcast of the present invention is described in detail below with reference to the accompanying drawings and the electric vehicle and the charging pile.
As shown in fig. 1, the automatic authentication method based on wireless broadcast of the present invention mainly includes: step S110, the electric automobile sends authentication request information through a WIFI detection request; step S120, the charging pile receives the WIFI detection request and the authentication request information; step S130, the charging pile matches the received authentication request information with prestored legal authentication information; and step S140, judging whether the charging pile should pass the authentication request of the electric automobile or not according to the matching result.
Specifically, in step S110, when the charging gun is pulled out of the charging pile, the WIFI server on the charging pile is activated; when the rifle that charges inserts electric automobile's charging mouth, the WIFI customer end on the electric automobile is activated. More specifically, the authentication request information is added into a Vendor Specific field of the WIFI probe request, and the electric vehicle sends a WIFI probe request message with the authentication request information through the WIFI client. As an example, the method for adding the authentication request information to the packet of the WIFI probe request may be specifically implemented by the following procedures:
Figure BDA0001205874040000141
wherein the Vendor Specific mark Specific supplier, RSA is an asymmetric encryption algorithm
Method (Rivest-Shamir-Adleman).
Although a specific manner of adding the authentication request information to the WIFI probe request message is described herein, this manner is not limiting, and those skilled in the art may select other manners as needed as long as the authentication request information can be sent out while broadcasting the WIFI probe request message. Further, as an example, the authentication request information may include, but is not limited to, a vehicle frame number (VIN code) of the electric vehicle, an engine number (motor number), a battery number, a dedicated identification code preset and stored in the electric vehicle, or other numbers that can identify the identity of the electric vehicle. Changes and modifications in the information content do not depart from the basic concept of the present invention and thus fall within the scope of the present invention.
Specifically, in step S120, the charging pile receives, through the WIFI server, a packet of the WIFI detection request added with the authentication request information, and parses the authentication request information from the packet. Also as an example, the specific parsing process may be implemented by the following steps:
acquiring the information EnData of the Vendor Specific.
The original Data is obtained as RSA _ DESCRYPT (PubKeyRSA, EnData).
Virtual _ key _ charge ═ AES (SecretKeyAES, MD5(saltCode + timetag + vinCode)) is calculated according to a method agreed in advance.
Among them, AES is a symmetric Encryption algorithm (Advanced Encryption Standard).
Specifically, in step S130, the charging pile matches the authentication request information analyzed in step S120 with the pre-stored legal authentication information. As an example, the matching process may be performed by the following three determinations:
whether the vin _ code in the Data is in the locally saved VehicleVinCode;
whether the timestamp in Data is within n seconds of the current time (n can be configured to be 3s, 5s, 10s, etc.);
whether the virtual _ key _ vehicle in the Data is the same as the calculated virtual _ key _ charge.
And when the three judgments are all satisfied, the authentication is passed, otherwise, the authentication is not passed.
Similarly, although a specific message parsing and information matching manner is described herein, this manner is not limited, and a person skilled in the art may select another manner as needed as long as the authentication request information in the message added to the WIFI probe request can be parsed out and effectively compared. In addition, the analysis of the authentication request information and the matching of the analyzed authentication request information and the prestored legal authentication information are executed by the control module; when the control module is arranged on the charging pile, the analysis and matching operation is executed locally; when the control module is arranged on a remote end, such as a background server or a cloud server, the parsing and matching operations are performed on the remote end. Accordingly, the legal authentication information can be stored locally, namely on the charging pile, or can be stored at a remote end.
Specifically, in step S140, when the authentication request information matches the valid authentication information, the charging pile is allowed to provide a charging service for the electric vehicle; and when the authentication request information is not matched with the legal authentication information, the charging pile is not allowed to provide the charging service for the electric automobile.
As can be understood by those skilled in the art, in the preferred technical scheme of the invention, the electric vehicle sends the message of the WIFI detection request added with the authentication request information through the WIFI client, the charging pile receives the message through the WIFI server, and then the charging pile matches the received authentication request information with the pre-stored legal authentication information through the control module arranged at the local or remote end. When the received authentication request information is matched with the pre-stored legal authentication information, the charging pile passes the authentication request of the electric automobile; otherwise, the charging pile refuses the authentication request of the electric automobile.
Because the object to be charged and replaced carries the authentication request information while sending the WIFI detection request, the object to be charged and replaced can also ensure that the object to be charged and replaced can send the authentication request information to the charging and replacing facility without establishing WIFI connection, so that the charging and replacing facility can quickly authenticate the object to be charged and replaced, authentication can be realized under the condition that the object to be charged and replaced cannot be networked (SSID (service set identifier) and passsword information of WIFI (wireless fidelity) are not required to be injected through a network), meanwhile, the information sending step of the whole WIFI authentication process is greatly simplified, and the charging and replacing experience of a user is improved.
Those skilled in the art can understand that the technical solution of the present invention described above with reference to fig. 1 is based on the active scanning WIFI establishing mode, but the present invention is obviously not limited to this mode, and the technical solution of the present invention can also be applied to the passive scanning WIFI establishing mode. Specifically, in a passive scanning WIFI establishing mode, a WIFI server arranged on the electric vehicle actively broadcasts a Beacon Frame (Beacon Frame), similar to the active scanning mode, authentication request information can be added into a vendor specific field of the Beacon Frame (Beacon Frame), a WIFI client arranged on the charging pile scans and receives the Beacon Frame sent by the WIFI server, and then the authentication request information is analyzed from the vendor specific field of the Beacon Frame and is compared, matched and judged with legal authentication information.
Referring to fig. 2, as shown in fig. 2, the method for automatically authorizing an object to be charged based on WIFI broadcast of the present invention includes: step S210, the electric automobile sends authentication request information through a WIFI detection request; and step S220, the electric automobile accepts charging or is refused to charge according to the matching result of the authentication request information and the pre-stored legal authentication information.
It should be noted that, the above has described in detail the steps of adding the authentication request information to the WIFI probe request, parsing the authentication request information from the WIFI probe request, and matching the authentication request information with the valid authentication information, so that the details are not repeated here.
Referring next to fig. 3, as shown in fig. 3, the method for authorizing a charging and swapping facility based on WIFI broadcasting of the present invention includes: step S310, the charging pile receives a WIFI detection request with authentication request information; step S320, the charging pile matches the received authentication request information with prestored legal authentication information; step S330, according to the matching result of the authentication request information and the pre-stored legal authentication information, the charging pile determines whether to provide the charging service.
Similarly, the above has described in detail the steps of adding the authentication request information to the WIFI probe request, parsing the authentication request information from the WIFI probe request, and matching the authentication request information with the valid authentication information, so that the details are not repeated here. However, it should be noted that, here, the step of "the charging pile matches the received authentication request information with the pre-stored legal authentication information" may also be performed at the charging pile or at a remote end.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
