All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
The vehicle-mounted navigation system is a special vehicle informatization product which is developed specially aiming at the special operating environment of the vehicle and the characteristics of an electric circuit, has the functions of high temperature resistance, dust resistance and shock resistance, and can be fused with an electronic circuit of the vehicle, supports the functions of internet surfing, audio-visual entertainment, satellite positioning, voice navigation, games, telephones and the like in the vehicle, and can realize the specific functions of visual backing, fault detection and the like. With the development of technologies such as vehicle-mounted electronics, intelligent driving, vehicle networking and the like, vehicle-mounted navigation systems are increasingly applied in the automobile industry. The vehicle-mounted navigation system is used as a central control device of automobile electronics, is connected with a plurality of key electronic devices of an automobile, and can realize control over various functions of an automobile body.
At present, most background management entry access modes provided by vehicle navigation systems are realized by a system hidden interface method, the entry management method is only locally managed, and password content is only unchanged. In the management mode, the opening of the background management entrance needs complex operation steps, the entrance position is easy to expose, the safety cannot be reliably guaranteed, and the entrance is easy to crack and illegally intrude. In view of the above, embodiments of the present invention provide a method for generating a key in a background of a car navigation system, so as to alleviate the technical problems mentioned above.
Example one
Fig. 1 is a flowchart of a key generation method for a vehicle navigation system background according to an embodiment of the present invention, where the method is applied to a management terminal, and as shown in fig. 1, the method specifically includes the following steps:
and step S102, acquiring the authorization information of the generated key.
Specifically, the management terminal in the embodiment of the present invention may be implemented by a PC, a smart phone, a tablet computer, and the like, and in order to improve convenience and security of the background management entry of the vehicle navigation system, the inventor thinks of a solution that the background management entry can be quickly opened by using a simple storage device connection, where the storage device may be a simple USB storage device, such as a USB disk. That is, the storage device is used as a key of the background of the car navigation system, and the background management entrance is opened immediately as long as a correct key is inserted.
When the management terminal makes a key, firstly, authorization information for generating the key is acquired, that is, the key needs to be made according to the authorization information, wherein the authorization information includes: the vehicle-mounted navigation equipment information matched with the key and the attribute information of the storage equipment inserted into the management terminal. Optionally, the acquiring of the authorization information by the management terminal may be accomplished by a user directly inputting information through an interactive interface of the management terminal, or by selecting from a preset candidate list, or by a user directly importing a file including the authorization information into the management terminal.
The vehicle-mounted navigation equipment is used as a carrier of background application of the vehicle-mounted navigation system, in order to ensure the unique corresponding relation between the key and the vehicle-mounted navigation system, when the key is manufactured, the vehicle-mounted navigation equipment information corresponding to the key is used as necessary acquisition information, and in order to prevent illegal copying of the key, attribute information of storage equipment inserted into the management terminal is required to be acquired. The attribute information of the storage device includes: device name, drive letter, supplier identification code, product identification code, serial number, manufacturer information, product information, version, etc. generally, authorization information generally selects supplier identification code, product identification code, and serial number for use.
And step S104, generating a key file of the key based on the authorization information.
After the authorization information is obtained, the management terminal needs to generate a key file of a background key of the vehicle navigation system according to the authorization information, wherein the key file is an encrypted file with a limited format and is mainly used for storing an encrypted ciphertext, and the encrypted ciphertext is generated by encrypting based on the authorization information.
And step S106, importing the key file into the storage device.
Next, the management terminal generates a key file, and then introduces the key file into the storage device so that the storage device holds the key file. In addition, a file can be optionally created in the storage device, and then the encrypted ciphertext generated based on the authorization information described above is written into the created file.
In order to further enhance the security of the key, enable the key to have uniqueness and prevent illegal copying, the key making time information can be added into the authorization information generated by the management terminal, so that after the key file is generated by the management terminal, the difference between the key file creating time information and the key making time information can be within a certain time range only by importing the key file into the storage device within the preset specified time, and after the key file is verified by the vehicle-mounted navigation device, the validity of the key file can be verified according to the time difference between the key file creating time and the key making time.
And S108, recording the key stamp into the storage device so as to use the storage device carrying the key stamp as a background key of the vehicle navigation system.
After the key file is determined to be imported into the storage device, in order to further enhance the security of the key, the management terminal records a key stamp in the storage device by a software method, so that the key stamp is used as a key feature of a background key of the vehicle-mounted navigation system, that is, the key stamp is used for representing an anti-counterfeiting mark, and the vehicle-mounted navigation system can identify whether the storage device connected with the vehicle-mounted navigation system is the background key or not by the mark. The embodiment of the invention does not specifically limit the method for recording the key stamp into the storage device, and a user can set the method according to actual requirements.
After the burning of the key stamp is completed, the storage device becomes a physical main body of the vehicle navigation system background key, that is, only the storage device containing the key file and the key stamp can become the vehicle navigation system background key.
The invention provides a key generation method of a vehicle navigation system background, which comprises the steps of firstly, acquiring authorization information for generating a key; wherein, the authorization information includes: the vehicle-mounted navigation equipment information matched with the key and the attribute information of the storage equipment inserted into the management terminal; then generating a key file of the key based on the authorization information; next, importing the key file into a storage device; and finally, recording the key stamp into the storage device so as to use the storage device carrying the key stamp as a key of the background of the vehicle-mounted navigation system. According to the method, the key manufacturing of the vehicle-mounted navigation system background can be completed by using the common storage equipment, and the vehicle-mounted navigation equipment information and the attribute information of the storage equipment are bound in the key, so that the illegal copying of the key can be effectively prevented. The user can quickly open the management background through simple storage device connection, and the rapidness, operability and safety of the operation of the management background entrance are effectively improved.
In an optional implementation manner, the step S104 of generating a key file of the key based on the authorization information specifically includes the following steps:
step S1041, encoding the authorization information by using a preset encoding method to obtain encoded authorization information.
Specifically, since the information types included in the authorization information are not uniform, after the authorization information is acquired, the management terminal needs to encode the authorization information to obtain encoded authorization information, where each encoded authorization information may be a string of numbers or a character string, that is, the encoding may be understood as a format normalization arrangement of the authorization information.
Step S1042, sorting the encoded authorization information based on a preset sorting rule to obtain sorted authorization information.
Since the authorization information includes multiple types of data, after the encoding processing, the encoded authorization information needs to be sorted, so that the encryption processing in the subsequent steps is performed in different sorting manners, and ciphertexts obtained by encryption are different, so that the sorting manner can also be used as a check condition.
And S1043, encrypting the sequenced authorization information by using a preset encryption algorithm to obtain a target ciphertext.
After the sequenced authorization information is obtained, the management terminal encrypts the authorization information by using a preset encryption algorithm to obtain a target ciphertext, wherein the preset encryption algorithm can use the existing encryption algorithm, and the embodiment of the invention does not specifically limit the encryption algorithm, and can adopt the following steps: MD5, RSA, DSA, DES, etc. After the target ciphertext is obtained, in order to prevent the key file from being illegally tampered, the target ciphertext also comprises an authorization information check code; the authorization information check code is obtained by utilizing the preset encryption algorithm to encrypt the authorization information and then calculating according to an encryption result.
And step S1044, storing the target ciphertext into a preset file, and using the preset file in which the target ciphertext is stored as a key file.
In an alternative embodiment, after obtaining the key file, before importing the key file into the storage device, the method of the present invention further includes the following steps:
step S105, performing read-write protection processing on the key file to obtain a read-write protected key file. That is, after step S105, the key file is a protection file, and the unspecified device cannot delete or modify the key file, wherein the specified device includes: the management terminal and the vehicle navigation equipment matched with the key.
In an optional implementation manner, in step S106, the key stamp is recorded into the storage device, which specifically includes the following contents:
performing preset partition operation on the storage device, and using a partition mark as a key mark; or writing a preset identification file into the storage device, and taking the preset identification file as a key stamp.
If the storage device is a usb disk, performing a predetermined partition operation on the storage device may be understood as specially dividing a storage area in the storage space of the usb disk, naming or performing other special processing on the storage area, and marking the usb disk as having the predetermined storage area, so that the partition mark may be used as a feature identifier (key stamp). Or, a preset identification file with a special mark (a special naming mode or special storage content, etc.) is preset, and then the preset identification file is written into the storage device, so that the preset identification file can also be used as a key mark. The two optional recording methods of the key stamp are provided, and a user can select other methods to realize recording of the key stamp according to actual requirements.
In an optional embodiment, the authorization information of the key further includes: key user information, usage time information, usage number information, key creation time information, and key management level information. The method of the invention also comprises the following steps: and uploading the authorization information of the key to a specified cloud server.
In order to make the use of the key controllable, the use time information and the use frequency information may be added to the authorization information of the key, and the use time and the use frequency may be checked each time the key is used, so as to prevent operations other than authorized use time and authorized use frequency.
For example, if the used time information is set to be 2020-1-2030-1, the background cannot be opened by using the key outside the above time; the using time information can be set according to the specific requirements of the user, and can also be a specified time period every day.
Assuming that the information of the number of times of use is 50 times, the vehicle-mounted navigation system updates the number of times of use each time the key is used, and if the vehicle-mounted navigation system analyzes that the number of times of use of the key reaches 50 times, the vehicle-mounted navigation system cannot authorize the key to enter the background.
Furthermore, key user information and key management level information can be added to the key authorization information, a vehicle navigation system can be provided with a plurality of keys, and different keys can be configured with different user information and management level information. The key user information represents the object of the key; the management level information of the key represents the management authority of the key, when the key is manufactured, the management terminal can set the management authority of the key according to the information of a key user or other related information, and different management levels correspond to different background management interfaces so as to prevent the lower-level key from being illegally set for the vehicle navigation system. Fig. 2 is a schematic diagram of an optional process of encoding authorization information and determining an authorization information check code according to an embodiment of the present invention.
In order to further improve the security of the system, after the management terminal generates the key, the management terminal uploads the authorization information of the key to the specified cloud server, so that the attribute information of the storage device and the key configuration information (the number of use times, the use time, the manufacture time and the like) are bound, and the key is prevented from being illegally copied. The specified cloud server is provided with a cloud database, and the cloud database realizes centralized storage and management of key information. Based on the method, the vehicle-mounted navigation system can verify the key through a method combining local verification and cloud verification, and even if one of the local or cloud is invaded or hijacked, the safety of the vehicle-mounted navigation background can be still ensured.
In summary, according to the key generation method for the vehicle navigation system background provided by the embodiment of the invention, in the key making process, the target ciphertext can be bound with the time by adding the key making time information, so that the key has uniqueness, and the illegal copying of the key can be effectively prevented; the use time information and the use frequency information are added into the authorization information, so that the operation except the authorized use time and the authorized use frequency can be effectively prevented, and the key has controllability; the attribute information of the storage device is used as the necessary information for making the key file, and the illegal copying of the key can be prevented; furthermore, a cloud verification mode is introduced on the basis of local verification, and the safety of the vehicle navigation background can be powerfully guaranteed. By using the key generated in the mode, a user can quickly open the management background through simple storage equipment connection, so that the operation rapidness, operability and safety of the management background entry are effectively improved, and the problems that the vehicle-mounted navigation background entry is easy to expose and crack are solved.
Example two
Fig. 3 is a flowchart of a key verification method for a vehicle navigation system background according to an embodiment of the present invention, where the method is applied to a vehicle navigation system, and as shown in fig. 3, the method specifically includes the following steps:
step S202, judging whether a legal key stamp is recorded in a storage device accessed to the vehicle-mounted navigation system.
Specifically, the vehicle-mounted navigation system in the embodiment of the present invention sets an application carrier for a factory, and may be implemented by a vehicle-mounted computer based on an Android system or a Linux system, which is commonly used in the prior art, or by a vehicle-mounted computer based on a WinCE system, a ucos ii system, or a ucos iii system.
After the vehicle-mounted navigation system detects that the storage device is accessed, a detection program for the storage device is automatically started, whether the connection is normal or not is judged, and key feature retrieval is carried out on the storage device under the condition that the connection is determined to be normal. Firstly, whether a legal key stamp is recorded in the accessed storage equipment is judged. In the first embodiment, the possible existence form of the key stamp has been described, so that in the determining step, only one corresponding search needs to be performed according to the possible occurrence form of the key stamp, and if the key stamp is only one of the partition mark and the preset identification file, only one search needs to be performed on the partition mark and the preset identification file in sequence in the search process. If the vehicle-mounted navigation system can acquire the legal key stamp in the storage device, the storage device can be preliminarily determined as the background key of the vehicle-mounted navigation system.
If yes, go to step S204; if not, determining that the storage equipment is not a key of the background of the vehicle-mounted navigation system, and processing the storage equipment according to the common external storage equipment.
Step S204, acquiring the key file in the storage device and the attribute information of the storage device.
After the vehicle navigation system acquires the legal key stamp, the key file and attribute information (hardware characteristics, such as supplier identification code, product identification code, serial number, and the like) of the storage device are further acquired from the storage device, so that the validity of the key can be detected in the subsequent steps. The key file may be obtained by searching for a file having a predetermined rule name or a file having a designated name from the storage device. And if the vehicle-mounted navigation system cannot acquire the key file from the storage equipment, processing the storage equipment according to the common external storage equipment.
And step S206, analyzing the key file to obtain the authorization information of the key, the authorization information check code and the attribute information of the key file.
