In the prior art, when a service company desires to write vehicle service information into an electronic car identifier to manage vehicle services related to a car corresponding to the electronic car identifier, the vehicle service information that is not processed is directly written into the electronic car identifier, as described above, various vehicle service information may be written into the electronic car identifier, and may include service information corresponding to vehicle services handled by different service companies, such as insurance service information corresponding to an insurance company, parking lot service information corresponding to a parking lot, and the like, while the vehicle service information is directly written into the electronic car identifier, which results in low security of the service information. For example, when the insurance company a reads the vehicle service information in the electronic car identifier, the parking lot service information corresponding to the parking lot stored in the electronic car identifier may be acquired, or the insurance company a may also acquire another insurance service information corresponding to the insurance company B stored in the electronic car identifier, that is, the vehicle service information stored in the electronic car identifier is easy to leak and has low security.
In view of this, embodiments of the present invention provide a method for writing in vehicle service information, by which vehicle service information can be encrypted by using an encryption key corresponding to the vehicle service information, and then the encrypted vehicle service information is written into an extensible area in an electronic identifier of a vehicle, so that the possibility that the vehicle service information stored in the electronic identifier of the vehicle is leaked can be reduced by means of encryption writing, thereby improving the security of the vehicle service information and further improving user experience.
The method for writing in the vehicle service information provided by the embodiment of the present invention may be executed by a device having a function of writing in the vehicle service information, where the device may be, for example, a tablet computer, a Personal Digital Assistant (PDA), a notebook computer, a Radio Frequency Identification (RFID) reader, a personal computer, or other computing devices, and the device may also have an encryption function, for example, the device may perform encryption processing by using an encryption device.
The technical scheme provided by the embodiment of the invention is described in the following with the accompanying drawings of the specification.
Referring to fig. 1, an embodiment of the present invention provides a method for writing vehicle service information, which may be executed by the foregoing computing device. The specific flow of the method is described below.
Step 101: and determining vehicle service information needing to be written in the automobile electronic identification, wherein the vehicle service information comprises service information corresponding to transacted vehicle services.
The technical scheme for writing in the vehicle service information in the embodiment of the invention can be applied to application scenes which want to use the electronic automobile identifier to carry out service management, such as insurance companies, environmental protection management companies, common parking lots of vehicles and the like, and the electronic automobile identifier can be used in the application scenes to process related service information more quickly and efficiently, so that the working efficiency of service companies is improved.
In practical applications, the electronic car identifier, also called as an electronic car id card, a digital car standard information source, is commonly called as an electronic license plate, and is a chip installed in a car, and further, a plurality of regions may be included in the electronic car logo, for example, as shown in table 1, the electronic car logo includes a Chip Identifier (CID) region, a coding region, a vehicle registration information region, a user region, and a security region, and among the aforementioned regions, wherein the CID area, the coding area, the vehicle registration information area and the safety area can carry out identity authentication when data are read, for determining whether the car electronic identification is legitimate, further, the expandable area in the car electronic identification may be a user area, taking an insurance company as an example, the insurance company can write insurance service information corresponding to insurance services transacted by the user in the user area of the automobile electronic identifier.
TABLE 1
| Serial number | Storage area name | Data reading | Data writing |
| 1 | CID zone | Identity authentication | Non-writable |
| 2 | Coding region | Identity authentication and password verification | May not be changed after initialization |
| 3 | Vehicle registration information area | Identity authentication and password verification | Identity authentication and password verification |
| 4 | User area | Password verification | Password verification |
| 5 | Safety zone | Unreadable | Identity authentication and password verification |
When the vehicle service information needs to be written in the electronic automobile identifier, the vehicle service information needing to be written in the electronic automobile identifier may be obtained first, where the vehicle service information includes service information corresponding to the handled vehicle service, for example, if an insurance company needs to write insurance service information of a vehicle in the electronic automobile identifier, the insurance service information may include service information of a basic insurance corresponding to the handled insurance service, and may also include service information of an additional insurance corresponding to the handled insurance service, and the vehicle service information needing to be written in may be determined according to an actual situation, which is not limited in the embodiment of the present invention.
Step 102: an encryption key corresponding to the vehicle service information is obtained.
As described above, after the vehicle service information to be written with the electronic car identifier is determined, in order to realize the encrypted secure storage of the vehicle service information, the encryption key corresponding to the vehicle service information may be obtained.
In the embodiment of the present invention, the encryption key can be obtained roughly by generating the encryption key by the computing device itself and receiving the encryption key transmitted by the predetermined encryption device. The mode that the computing equipment generates the encryption key by itself is high in speed and high in obtaining efficiency; the mode of receiving the encryption key sent by the predetermined encryption device is, for example, that the computing device sends the vehicle service information to the predetermined encryption device, then the predetermined encryption device processes the vehicle service information to obtain the encryption key, and then the computing device receives the encryption key sent by the predetermined encryption device, that is, another alternative mode of obtaining the encryption key is provided on the mode of obtaining the encryption key by generating the encryption key by the computing device itself, so that the applicability and flexibility of the scheme are enhanced, and because the vehicle service information is sent to the predetermined encryption device to request the computing device to generate the encryption key, the problem that the computing device itself does not have an encryption function is considered, so that the encryption of the vehicle service information can be completed through cooperation between the devices.
In order to facilitate understanding of those skilled in the art, the following lists several possible ways to describe how to obtain the encryption key corresponding to the aforementioned vehicle service information, and it should be understood that the following examples are only illustrative and are not intended to limit embodiments of the present invention, and other obtaining ways may be adopted in the specific implementation process except for the ways listed below, which are not exhaustive herein.
First mode of acquisition
The root key may be obtained first, then the key element information in the vehicle service information is extracted according to a predetermined extraction rule, and an encryption key is generated according to the obtained root key and the extracted key element information, so as to obtain the encryption key.
In the first obtaining manner, the root key may be obtained first, and specifically, for example, a service company may input four groups of factors in the system of the computing device for generating the encryption key, where the factors may be composed of sixteen-bit hexadecimal characters, for example, as shown in the schematic diagram shown in fig. 2, the four groups of factors are respectively: factor one: aaaaaabbbbbbbbb; factor two: bbbbbbbbccccc; factor three: CCCCCCCCDDDDDDDD, respectively; factor four: DDDDDDDDAAAAAAAA, respectively; then, the generated encryption key system in the computing device is combined with the random number generated in advance to generate a root key, so as to obtain the root key, that is, the generated system key shown in fig. 2, in this way, the obtained root key is generated according to the random number generated at random and the factor input by the user, so that if other business companies want to obtain the root key, even if the factor input by the business company is known, the specific root key is difficult to obtain, and therefore, the security of the root key generated by the method is relatively high.
Further, in the first obtaining manner, some extraction rules may be predetermined, and for convenience of description, in the embodiment of the present invention, the predetermined extraction rules are referred to as predetermined extraction rules, and the predetermined extraction rules are used to extract key element information in the vehicle service information, specifically, the key element information may be a keyword in the vehicle service information, for example, the predetermined extraction rule may be to extract one keyword in the key element information in the insurance service information, such as an insurance contract number or an identity number of an insurer or a license plate number of an insured vehicle, or may be a set of multiple keywords in multiple key element information, such as a set of the insurance contract number, the license plate number of the insured vehicle, and an insurance contract year.
After the root key and the key element information are obtained, further, key distribution processing may be performed on the obtained root key using the key element information to obtain a plurality of distributed sub-keys, and then a final encryption key is determined according to the obtained plurality of distributed sub-keys.
Further, after obtaining the plurality of distributed sub-keys, one distributed sub-key may be directly selected from the plurality of distributed sub-keys as a final encryption key, or a certain combination process may be performed on the plurality of distributed sub-keys to obtain the final encryption key, or another manner may be adopted to obtain the encryption key according to the plurality of distributed sub-keys, which is not limited in this embodiment of the present invention.
Second mode of acquisition
The second obtaining method is similar to the first obtaining method in implementation principle, and is different from the first obtaining method in that the second obtaining method adds unique identification information of the electronic identifier of the vehicle on the basis of the first obtaining method, specifically, the unique identification information of the electronic identifier of the vehicle may be CID information, that is, a unique identifier of a chip.
Specifically, in the second obtaining manner, the identification information uniquely corresponding to the electronic identifier of the automobile may be obtained, and then the encryption key may be generated according to the obtained root key, the key element information, and the identification information, specifically, the obtained root key may be directly subjected to key dispersion processing according to the obtained key element information and the identification information, so as to generate the encryption key; the obtained root key can be dispersed according to the obtained key element information to obtain a first dispersed sub-key, then the first dispersed sub-key is subjected to secondary dispersion processing according to the unique identification information corresponding to the automobile electronic identification to obtain a second dispersed sub-key, and finally the obtained second dispersed sub-key is used as a final encryption key. Specifically, the encryption key is obtained by selecting any one of the above manners, which may be selected according to an actual application situation, and the embodiment of the present invention is not limited.
In the second obtaining method, because the information of the unique identification information of the electronic identifier of the automobile is added in the first obtaining method, the key distribution processing can be performed on the root key more specifically, and the complexity of the encryption key is further improved, so that the encryption key with higher security can be obtained.
Third mode of attainment
The computing device may transmit the vehicle service information to the predetermined encryption device, so that the predetermined encryption device generates an encryption key according to the vehicle service information, further, the predetermined encryption device may transmit the generated encryption key to the computing device, and the computing device may receive the encryption key transmitted by the predetermined encryption device.
In a specific implementation, when the computing device may not be able to locally generate the encryption key, the vehicle service information may be sent to a predetermined encryption device, where the predetermined encryption device may be an encryption device connected to the computing device, and then the predetermined encryption device may generate a final encryption key in a manner similar to the manner in which the computing device locally generates the encryption key in the first obtaining manner and the second obtaining manner, and then send the obtained encryption key to the computing device. Therefore, even if the computing equipment does not support the generation of the encryption key, the encryption key can be obtained in a mode of assistance of other equipment, the expansibility of the scheme is enhanced, and the experience of a user is improved.
Fourth mode of acquisition
The fourth obtaining mode is similar to the third obtaining mode, except that in the fourth obtaining mode, after the preset encryption device generates the encryption key, the vehicle service information can be directly encrypted by using the encryption key, and then the encrypted vehicle service information is sent to the computing device, so that transmission back and forth of plaintext information can be reduced, and information safety is further improved.
Through the several specific implementation modes for obtaining the encryption key, the encryption key can be accurately obtained, so that the subsequent processing work can be smoother, and the user experience is improved.
Step 103: and encrypting the vehicle service information by using the encryption key to obtain the encrypted vehicle service information.
As described above, after the encryption key corresponding to the vehicle service information is obtained, the vehicle service information is encrypted by the encryption key, so that the encrypted vehicle service information is obtained, and further, when the encrypted vehicle service information is obtained, the obtained encryption key can be deleted in time.
Step 104: and writing the encrypted vehicle service information into an expandable area in the automobile electronic identifier, wherein the expandable area is a storage area supporting writing and reading in the automobile electronic identifier.
As described above, after obtaining the encrypted vehicle service information, writing the encrypted vehicle service information into an extensible area in the electronic automobile identifier, where the extensible area is a storage area in the electronic automobile identifier, such as the user area in table 1, specifically, since all the vehicle service information can be written into the extensible area of the electronic automobile identifier, a start address and a memory area of the encrypted vehicle service information in the extensible area can also be determined, for example, if the encrypted eco-service information determines that the start address is 4 and the memory area is use _1, an operator of the eco-company can operate in a computing device, such as shown in fig. 3, inputting the previously determined start address is 4 and the memory area is use _1, and then the computing device receives the specific storage area of the encrypted eco-service information to be written, thereby completing the writing of the environmental protection service information,
further, in the embodiment of the present invention, after the encrypted vehicle information is written into the electronic car identifier, the computing device may display, as shown in fig. 4, a release number of the electronic car identifier, a time for importing the vehicle service information, unique identifier information of the electronic car identifier, license plate information, and plaintext data of the vehicle service information, that is, card writing data in fig. 4, are displayed in the system after the writing is completed, and further, the encrypted vehicle service information is stored in an extensible area of the electronic car identifier, that is, a user area.
Further, in the specific implementation process, when considering the situation that a service company may need to obtain vehicle service information in a plaintext to manage the vehicle service information, it may be further detected whether a reading trigger condition is met after deleting the encryption key, where the reading trigger condition may be that the vehicle service information needs to be updated, that a service validity time in the vehicle service information is about to expire soon, that a user manually triggers, or that other conditions are met, and when the trigger condition is met, the encrypted vehicle service information may be read from an expandable area of the electronic identifier of the vehicle, and a decryption key corresponding to the vehicle service information and matching with the encryption key is obtained, and then the obtained encrypted vehicle service information is decrypted by using the decryption key, so as to obtain the vehicle service information in the plaintext, and then, the content of the vehicle service information is adjusted according to the specific vehicle service information needing to be changed, so that the safety of writing the vehicle service information can be improved, the normal replacement of the vehicle service information can be ensured, and the user experience is improved. The decryption key can be obtained similarly to the above-mentioned obtaining manner of the encryption key, and is not described here again.
In the embodiment of the invention, when it is desired to write the vehicle service information into the expandable area in the electronic identifier of the vehicle, the vehicle service information to be written into the electronic identifier of the vehicle, such as insurance service information of the vehicle, is obtained, the encryption key corresponding to the vehicle service information is obtained, the vehicle service information is encrypted by using the encryption key, and the encrypted vehicle service information is written into the expandable area in the electronic identifier of the vehicle to complete the secure writing of the vehicle service information, that is, the vehicle service information is encrypted and written, so that even if other companies can obtain the vehicle service information by a password, since the encrypted vehicle service information is obtained, the possibility that the vehicle service information is leaked can be reduced, thereby improving the security of the vehicle service information, and the encryption key encrypted for the vehicle service information corresponds to the vehicle service information, the encryption key can be combined with each vehicle service information, and because each vehicle service information is different generally, the encryption level of the encryption key can be enhanced, and the pertinence can be stronger, so that the safety of the vehicle service information can be further improved, and the user experience is further improved.
