Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
[ First embodiment ]
As shown in fig. 1, a method for deriving a screen configuration file according to a first embodiment of the present invention includes the following steps:
s11: responding to the export instruction to obtain an authentication password;
S13: performing encryption operation on the authentication password by using an exclusive OR code to obtain an encrypted authentication password; and
S15: storing the encrypted authentication password to an authentication file, and encrypting the authentication file by using an encryption key to obtain an encrypted authentication file;
S17: reading a screen configuration file and encrypting the screen configuration file by using the encryption key to obtain an encrypted screen configuration file; and
S19: and exporting the encrypted authentication file and the encrypted screen configuration file to a target device.
In order to facilitate understanding of the present invention, each step of the screen configuration file derivation method of the present embodiment will be described in detail below.
The broadcasting device, such as a multimedia playing box, has a screen configuration file export and import function to update the screen configuration of the display screen. The screen configuration file herein includes, for example, a total screen load size, such as a total screen load size of a large screen formed by splicing a plurality of screens, a single screen port screen load number, a screen routing manner (or called a line connection manner between the screens), and/or a single screen size, such as resolution, etc. However, before the screen configuration file is imported into the broadcasting device, the screen configuration file needs to be exported from the host computer. The screen configuration file export method of this embodiment is generally implemented by using a screen configuration file export software on an upper computer, for example, by using multiple encryption passwords to encrypt and protect the screen configuration file to be exported. Then, when the screen configuration file is imported into the broadcasting device, the screen configuration file needs to be validated, for example, the screen configuration file can be imported after the corresponding multiple decryption passwords are validated. The passwords of the multiple encryption passwords and the corresponding passwords in the multiple decryption passwords can be the same or different, and only the paired passwords can be used. For example, the multiple encryption password includes, for example, an authentication password, an exclusive or code, and an encryption key. The exclusive or code and the encryption key in the multiple encryption password are used for encrypting the authentication password twice. The multiple decryption cipher includes, for example, an authentication cipher, an exclusive or code, and a decryption key. The exclusive or and the decryption key in the multiple decryption passwords are used for decrypting the encrypted file to obtain an authentication password. The authentication password in the multiple encryption passwords is the same as the authentication password of the multiple decryption passwords, and is used for identity verification when the screen configuration file is imported. The exclusive or code in the multiple encryption password is the same as the exclusive or code of the multiple decryption password. Whether the encryption key in the multiple encryption password is the same as the decryption key in the multiple decryption password can be determined according to different encryption and decryption modes, for example, when a DES (Data Encryption Standard ) mode is adopted, the encryption key is the same as the decryption key.
The exclusive-or code and the encryption key in the multiple encryption passwords can be configured or agreed in advance or can be configured dynamically. The advanced configuration refers to that the exclusive-or codes and the encryption keys in the multiple encryption passwords and the exclusive-or and decryption keys in the corresponding multiple decryption passwords are generated in advance and stored in the PC and the corresponding broadcasting control equipment in advance for acquisition and use, and the same multiple encryption passwords and multiple decryption passwords are used in each export and import operation in the later period.
The dynamic configuration refers to that the upper computer and the target broadcasting equipment are connected through the internet, a local area network, WIFI, bluetooth or lora and the like, the upper computer instantly generates an exclusive OR (exclusive OR) code and an encryption key in a multiple encryption password and a corresponding exclusive OR code and decryption key in a multiple decryption password, and sends the exclusive OR and decryption key in the multiple decryption password to a designated multimedia playing box such as an asynchronous playing box through the network. It should be noted that, the authentication password in the multiple encryption passwords and the authentication password of the multiple decryption passwords are preset or set on the PC and the broadcasting equipment. The upper computer encrypts the authentication password and the screen configuration file in the multiple encryption passwords by using the exclusive-or codes and the encryption keys, then exports the encrypted authentication password file and the screen configuration file to target equipment such as a USB flash disk, sends the exclusive-or and the decryption keys in the multiple decryption passwords to target broadcasting control equipment, decrypts the encrypted authentication password file and the encrypted screen configuration file in the USB flash disk, and imports the decrypted authentication password file and the encrypted screen configuration file to the target broadcasting control equipment. For another example, the upper computer encrypts the authentication password and the screen configuration file by using the exclusive-or code and the encryption key in the multiple encryption passwords, then exports the encrypted authentication password file and the screen configuration file to a target device such as a usb disk, and then sends the exclusive-or and the decryption key in the multiple decryption passwords to the server; when a screen manager connects a U disk storing the encrypted authentication password file and the screen configuration file to target broadcasting equipment, the target broadcasting equipment acquires an exclusive OR code and a decryption key in the multiple decryption passwords from a server, decrypts the screen configuration file to be imported and then imports the screen configuration file to the target broadcasting equipment. It should be mentioned here that the exclusive-or code and the encryption key in the multiple encryption passwords and the corresponding multiple encryption passwords, and the exclusive-or code and the decryption key in the multiple decryption passwords are randomly generated, so that confidentiality of the passwords and high protection and high reliability of the screen configuration file can be improved. In addition, as the multiple encryption passwords generated each time and the corresponding multiple decryption passwords can be different from the passwords generated other times, namely the exclusive or codes and the encryption keys in the multiple encryption passwords used by each time of export and import operation and the exclusive or code decryption keys of the multiple decryption passwords are different, the high protection and the high reliability of the screen configuration file are further improved.
The method for exporting the screen configuration file provided by the embodiment of the invention is described below by taking the fact that the authentication password in the multiple encryption password is the same as the authentication password in the multiple decryption password, the exclusive-or code in the multiple encryption password is the same as the exclusive-or code in the multiple decryption password, and the encryption key in the multiple encryption password is the same as the decryption key in the multiple decryption key.
First, an instruction is exported in response to a screen configuration file to obtain an authentication password. When the screen configuration file needs to be exported, a screen administrator performs screen configuration file export operation on screen configuration file export software, and the screen configuration file export software responds to a screen configuration file export instruction to obtain an authentication password. Specifically, the screen configuration file export software responds to the screen configuration file export instruction to automatically display an input interface for the user to input a pre-agreed authentication password. After the user inputs the authentication password and confirms, the authentication password is read in response to the user operation instruction. The authentication password is used for checking the identity legitimacy of the screen administrator when the screen configuration file is imported into the broadcasting control device.
And then, the exclusive OR code is utilized to carry out encryption operation on the authentication password to obtain an encrypted authentication password. The method specifically comprises the following steps: and performing exclusive-or operation on the authentication password and the exclusive-or code to finish one-time encryption of the authentication password. Of course, the exclusive or code may be used to perform other encryption operations on the authentication code to obtain an encrypted authentication code.
And then, storing the encryption authentication password into a file to obtain an authentication file, and encrypting the authentication file by using an encryption key to obtain an encryption authentication file. Thus, the secondary encryption of the authentication password is completed. The encryption method used here may be, for example, a symmetric encryption method such as DES encryption method, but other encryption methods may be used.
And secondly, reading the screen configuration file and encrypting the screen configuration file by using the encryption key to obtain an encrypted screen configuration file. The encryption method used here may be, for example, a symmetric encryption method such as DES encryption method, but other encryption methods may be used.
And finally, the encrypted authentication file and the encrypted screen configuration file are exported to the target device. The target device herein may be, for example, a mobile storage device such as a usb disk, a mobile hard disk, or the like. Of course, the target device may also be a broadcasting device that needs to be updated in screen configuration, for example, the PC is connected to the broadcasting device through a network cable, so that the PC may directly send the encrypted authentication file and the encrypted screen configuration file, and the xor code and the decryption key to the broadcasting device through the network.
Further, after the encrypted authentication file and the encrypted screen configuration file are exported to the target device, the exclusive-or code and the encryption key are sent for the target broadcasting device to acquire. It can be understood that the PC may directly send the xor code and the encryption key to the target broadcasting device, or may send the xor code and the encryption key to the server, so that the target broadcasting device connected to the server may acquire the xor code and the encryption key at any time. The target broadcasting device here is, for example, a broadcasting device that needs to update a screen configuration.
In summary, the embodiment of the invention can ensure high protection and high reliability in the process of exporting the screen configuration file by encrypting the authentication password twice and encrypting the screen configuration file once. In addition, the exclusive-or codes and the encryption keys in the multiple encryption passwords and the exclusive-or and decryption keys in the multiple decryption passwords are dynamically and randomly generated, and the exclusive-or and decryption keys are sent to the target broadcasting control equipment through the network after the encrypted screen configuration file is derived, so that the high protection and the high reliability of the screen configuration file can be further improved. In addition, different passwords are dynamically generated in each importing and exporting operation, so that confidentiality and protection of the screen configuration file are further facilitated.

The screen profile derivation apparatus 100 includes, for example: an authentication password acquisition module 110, an authentication password encryption module 130, an authentication file encryption module 150, a screen configuration file encryption module 170, and a file export module 190.

The authentication password encryption module 130 is configured to perform an encryption operation on the authentication password by using an exclusive or code to obtain an encrypted authentication password.
And the authentication file encryption module 150 is configured to store the encrypted authentication password into an authentication file, and encrypt the authentication file with an encryption key to obtain an encrypted authentication file.

And the file export module 190 is configured to export the encrypted authentication file and the encrypted screen configuration file to a target device.
Further, the screen configuration file deriving device 100 further includes a password transmitting module 120. The password sending module 120 is configured to send the xor code and the encryption key for the broadcasting control device to obtain; the target device is a mobile storage device used for importing the encrypted authentication file and the encrypted screen configuration file to the broadcasting device, or the target device is the broadcasting device.
The specific working procedure and technical effects between the modules in the screen profile derivation apparatus 100 in this embodiment are described in the foregoing first embodiment.
[ Third embodiment ]
As shown in fig. 3, a method for importing a screen configuration file according to a third embodiment of the present invention includes the following steps:
S31: responding to the imported instruction to read the encrypted authentication file on the target device;
S33: decrypting the encrypted authentication file by using a decryption key to obtain an authentication file;
s35: reading an encrypted authentication password in the authentication file, and decrypting the encrypted authentication password by using an exclusive or code to obtain an authentication password; and
S37: and when the authentication password is consistent with the authentication password, reading the encrypted screen configuration file on the target device, and decrypting the encrypted screen configuration file by using the decryption key to obtain the screen configuration file for screen configuration.
In order to facilitate understanding of the present invention, each step of the screen configuration file importing method of the present embodiment will be described in detail below.
When the screen body of the LED display screen connected with the broadcasting equipment needs to be updated, the screen body administrator imports the new screen body configuration file from the target equipment to the broadcasting equipment so as to update the screen body configuration through the broadcasting equipment. The target device herein may be, for example, a mobile storage device such as a usb disk, a mobile hard disk, or the like. In addition, the target device may also be a PC that stores a new screen configuration file. For example, the broadcasting equipment is connected with the PC through a network, so that the broadcasting equipment can directly import the screen configuration file from the PC through the network to update the screen configuration. In order to ensure the legitimacy of the imported screen configuration file, the imported screen configuration file needs to be subjected to legitimacy verification, so that high protection and high reliability of the imported screen configuration file are ensured. The screen configuration file importing method of the embodiment can be realized through terminal software on broadcasting control equipment, for example, the legitimacy of the file needing importing is verified through a used password. The method for importing the screen configuration file provided in the embodiment is described below by taking a USB flash disk as an example.
And reading the encrypted authentication file on the target device in response to the screen configuration file import instruction. When the screen configuration file needs to be imported, a screen administrator connects the U disk with the target broadcasting equipment. After the screen administrator performs corresponding operations on the broadcasting equipment, for example, clicking a screen configuration file import button, a terminal program on the broadcasting equipment responds to a user operation instruction to read an encrypted authentication file in the U disk. The encrypted authentication file here may be, for example, the encrypted authentication file in the first embodiment of the present invention. Of course, before reading the encrypted authentication file on the target device, the authentication password needs to be preset or agreed, and the xor code and the decryption key need to be obtained. The exclusive or and decryption keys are received, for example, from a PC or server by means such as internet, local area network, WIFI, bluetooth or lora. The xor and decryption keys here are in one-to-one correspondence with the xor codes and encryption keys, respectively, in the first embodiment of the present invention, and even the same.
And decrypting the encrypted authentication file by using the decryption key to obtain the authentication file. The decryption method used here may be, for example, a DES decryption method, but other decryption methods may be used. This completes one decryption of the authentication password.
Reading the encrypted authentication password in the authentication file, and decrypting the encrypted authentication password by using an exclusive or code, wherein the method specifically comprises the following steps: and carrying out exclusive-or operation on the encryption authentication password and a preset exclusive-or code. This completes the secondary decryption of the authentication password.
And judging whether the decrypted authentication password is consistent with the authentication password received or stored by the broadcasting control equipment. When the authentication password is inconsistent with the authentication password, the identity verification is failed, which means that the screen configuration file importing operation is not executed by a screen administrator, and the terminal program immediately terminates the screen configuration file importing flow. And when the authentication password is consistent with the authentication password, indicating that the authentication is successful, meaning that the screen configuration file importing operation is executed by a screen administrator, then reading the encrypted screen configuration file in the U disk, and decrypting the encrypted screen configuration file by using a decryption key. The decryption method used here may be, for example, a DES decryption method, but other decryption methods may be used. And when the encrypted screen configuration file is successfully decrypted to obtain the screen configuration file, importing the screen configuration file, and then configuring the LED display screen by the broadcasting equipment according to the screen configuration file. And when the encrypted screen configuration file is decrypted and the screen configuration file is not obtained, indicating that the screen configuration file is illegal, and immediately terminating the screen configuration file importing flow by the terminal program.
In summary, the embodiment of the invention can ensure that the screen configuration file importing operation can only be completed by appointed personnel (display screen management personnel) through target equipment by decrypting the authentication password twice and decrypting the screen configuration file once, thereby avoiding the possibility of illegal molecules tampering with the display screen to play programs and improving the high protection and high reliability of the screen configuration file updating process of the broadcasting control equipment.
