Description

Technical Field

[0001] The present invention relates to the field of electronic information technology, and in particular to a method and system for setting signal permissions of a signal source through software. Background Art

[0002] In recent years, with the intensification of market competition and the improvement of corporate development needs, improving work efficiency has become the focus of attention in all walks of life. The old version of the signal source sold needs to be returned to the factory for upgrading before being sent to the customer to change the signal permissions, which reduces work efficiency. Summary of the invention

[0003] In order to solve the deficiencies mentioned in the above background technology, the purpose of the present invention is to provide a method and system for setting signal permissions of a signal source through software, so that customers can set signal permissions of the signal source through software without returning the signal to the factory.

[0004] In a first aspect, the purpose of the present invention can be achieved by the following technical solution: A method for setting signal permissions of a signal source by software, the method comprising the following steps:

[0005] Receive the set signal authority, input the set signal authority into the ciphertext generating upper computer, and output the ciphertext file;

[0006] Send the ciphertext file to the signal source through the network port of the upper computer that sends the ciphertext;

[0007] The signal source parses the ciphertext file, sets new signal permissions based on the analysis, inputs the new signal permissions into the signal source host computer, reads the signal permissions and displays the open signals for users to use.

[0008] In combination with the first aspect, in some implementations of the first aspect, the method further includes: a process of inputting the setting signal authority into a ciphertext generating upper computer and outputting a ciphertext file:

[0009] Generate ciphertext The host computer mixes the product serial number, option signal permission variable, and key, and encrypts them using the BASE16 encryption algorithm. After encryption, a CRC8 check is performed to finally generate a ciphertext file.

[0010] In combination with the first aspect, in some implementations of the first aspect, the method further includes: the calculation process of encrypting by the BASE16 encryption algorithm:

[0011] For example, if the sent data is 3,6, according to the ASCII table, the ASCII value of 3 is 51, and the ASCII value of 6 is 54;

[0012] 51 is converted to binary 00110011, the high four bits are 3 (decimal), the low four bits are 2 (decimal)

[0013] 54 is converted to binary 00110110, the high four bits are 3 (decimal), the low four bits are 6 (decimal)

[0014] Finally, the data obtained after BASE16 encrypts 3,6 is 3,3,3,6.

[0015] In combination with the first aspect, in some implementations of the first aspect, the method further includes: a calculation process of performing CRC8 check after encryption:

[0016] Formula 1: T(x) = f(x)*2 k +R(x),

[0017] Formula 2: R(x) = f(x)*2 k / G(x)

[0018] In the above formula, T(x) represents the sending code, R(x) represents the check code, f(x) represents the data to be transmitted, G(x) represents the polynomial agreed upon by the sender and receiver, and k is equal to the length of G(x) minus 1.

[0019] For example, if the transmitted data f(x) is 0x92, converted to binary 101001, then f(x) = 101001, and the polynomial convention is G(x) = X 3 +X 2 +X 0 , expressed in binary G(x) = 1101, length is 4

[0020] k is equal to the length of G(x) minus 1, then k = 3;

[0021] In the formula, f(x)*2 k =101001*2 3 =101001000

[0022] R(x)=f(x)*2 k / G(x)=101001000 / 1101, take the remainder 3 digits 001

[0023] T(x)=f(x)*2 k +R(x)=101001001

[0024] When the receiving end divides the received data by G(x), if the remainder is 0, it means the received data is correct, otherwise it is wrong.

[0025] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: converting the data into corresponding binary numbers using the BASE16 encryption algorithm;

[0026] Then string all the binary numbers together, with 4 binary bits as a group, and convert them into the corresponding decimal numbers;

[0027] Find the corresponding character in the Base16 encoding table according to the decimal value.

[0028] In combination with the first aspect, in some implementations of the first aspect, the method further includes: the CRC8 check process is as follows:

[0029] Set an 8-bit register to 0

[0030] XOR the byte with the highest bit of the register; shift the register left by one bit; if the XOR result is 1, XOR the register with a predefined polynomial

[0031] Repeat the above byte processing process until all bytes are processed

[0032] The final value in the register is the CRC check code.

[0033] In combination with the first aspect, in some implementations of the first aspect, the method further includes: a process in which the signal source parses the ciphertext file:

[0034] The signal source receives the ciphertext file through the network port, and then performs a CRC8 check. After the check passes, it starts to use the BASE16 decryption algorithm to decrypt the product serial number, the option signal permission variable, and the key to obtain a mixed value. The product serial number is extracted from the mixed value and compared with the signal source serial number. After the comparison is successful, the option signal permission variable is extracted from the mixed value using the key and stored in the chip. Finally, the signal is selected whether to be open based on the option signal permission variable.

[0035] In a second aspect, in order to achieve the above-mentioned object, the present invention discloses a system for setting signal permissions by software for a signal source, comprising:

[0036] The ciphertext generation module is used to receive the set signal authority, input the set signal authority into the ciphertext generation host computer, and output the ciphertext file;

[0037] The ciphertext transmission module is used to send the ciphertext file to the signal source through the network port of the upper computer that sends the ciphertext;

[0038] The ciphertext parsing module is used for the signal source to parse the ciphertext file, set new signal permissions according to the analysis, input the new signal permissions into the signal source host computer, read the signal permissions and display the open signals for users to use.

[0039] In conjunction with the second aspect, in some implementations of the second aspect, the system further includes: the ciphertext generation module inputs the set signal authority into the ciphertext generation host computer, and outputs a process of obtaining a ciphertext file:

[0040] Generate ciphertext The host computer mixes the product serial number, option signal permission variable, and key, and encrypts them using the BASE16 encryption algorithm. After encryption, it performs a CRC8 check to finally generate a ciphertext file.

[0041] The calculation process of encryption using the BASE16 encryption algorithm:

[0042] For example, if the sent data is 3,6, according to the ASCII table, the ASCII value of 3 is 51, and the ASCII value of 6 is 54;

[0043] 51 is converted to binary 00110011, the high four bits are 3 (decimal), the low four bits are 2 (decimal)

[0044] 54 is converted to binary 00110110, the high four bits are 3 (decimal), the low four bits are 6 (decimal)

[0045] Finally, the data obtained by BASE16 encrypting 3,6 is 3,3,3,6

[0046] The calculation process of CRC8 check after encryption:

[0047] Formula 1: T(x) = f(x)*2 k +R(x),

[0048] Formula 2: R(x) = f(x)*2 k / G(x)

[0049] In the above formula, T(x) represents the sending code, R(x) represents the check code, f(x) represents the data to be transmitted, G(x) represents the polynomial agreed upon by the sender and receiver, and k is equal to the length of G(x) minus 1.

[0050] For example, if the transmitted data f(x) is 0x92, converted to binary 101001, then f(x) = 101001, and the polynomial convention is G(x) = X 3 +X 2 +X 0 , expressed in binary G(x) = 1101, length is 4

[0051] k is equal to the length of G(x) minus 1, then k = 3;

[0052] In the formula, f(x)*2 k =101001*2 3 =101001000

[0053] R(x)=f(x)*2 k / G(x)=101001000 / 1101, take the remainder 3 digits 001

[0054] T(x)=f(x)*2 k +R(x)=101001001

[0055] When the receiving end divides the received data by G(x), if the remainder is 0, it means the received data is correct, otherwise it is wrong.

[0056] The BASE16 encryption algorithm converts the data into corresponding binary numbers;

[0057] Then string all the binary numbers together, with 4 binary bits as a group, and convert them into the corresponding decimal numbers;

[0058] Find the corresponding character in the Base16 encoding table according to the decimal value;

[0059] The CRC8 verification process is as follows:

[0060] Set an 8-bit register to 0

[0061] XOR the byte with the highest bit of the register; shift the register left by one bit; if the XOR result is 1, XOR the register with a predefined polynomial

[0062] Repeat the above byte processing process until all bytes are processed;

[0063] The final value in the register is the CRC check code;

[0064] The process of the signal source in the ciphertext parsing module parsing the ciphertext file:

[0065] The signal source receives the ciphertext file through the network port, and then performs a CRC8 check. After the check passes, it starts to use the BASE16 decryption algorithm to decrypt the product serial number, the option signal permission variable, and the key to obtain a mixed value. The product serial number is extracted from the mixed value and compared with the signal source serial number. After the comparison is successful, the option signal permission variable is extracted from the mixed value using the key and stored in the chip. Finally, the signal is selected whether to be open based on the option signal permission variable.

[0080] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0081] Embodiment 1:

[0082] The following is an introduction to the relevant terms involved in the embodiments of the present application:

[0083] Encryption algorithm: The basic process of data encryption is to process the original plain text file or data according to a certain algorithm, making it an unreadable code called "ciphertext", so that it can only be displayed after the corresponding key is entered. In this way, the purpose of protecting data from being stolen or read by illegal persons is achieved. The reverse process of this process is decryption, which is the process of converting the encoded information into its original data.

[0084] like Figure 1 As shown, a method for setting signal permissions of a signal source through software includes the following steps:

[0085] S101: receiving a setting signal authority, inputting the setting signal authority into a ciphertext generating upper computer, and outputting a ciphertext file;

[0086] The process of inputting the set signal authority into the ciphertext generating host computer and outputting the ciphertext file:

[0087] Generate ciphertext The host computer mixes the product serial number, option signal permission variable, and key, and encrypts them using the BASE16 encryption algorithm. After encryption, it performs a CRC8 check to finally generate a ciphertext file.

[0088] The specific design process of the ciphertext host computer is as follows: First, design the ciphertext host computer UI interface, as follows Figure 4 Each product has a different serial number, so you are required to enter a different serial number to enhance the confidentiality and uniqueness of the product. The option function area allows you to select the signal source and various signal permissions. The signal permission of this option is turned on, and the □ code means the permission of this option is turned off. It means that the signal permission of this option will not be changed. After clicking Generate Ciphertext, the ciphertext will be displayed in the right box and a ciphertext file will be generated.

[0089] The calculation process of encryption using the BASE16 encryption algorithm is as follows:

[0090] For example, if the sent data is 3,6, according to the ASCII table, the ASCII value of 3 is 51, and the ASCII value of 6 is 54;

[0091] 51 is converted to binary 00110011, the high four bits are 3 (decimal), the low four bits are 2 (decimal)

[0092] 54 is converted to binary 00110110, the high four bits are 3 (decimal), the low four bits are 6 (decimal)

[0093] Finally, the data obtained by BASE16 encrypting 3,6 is 3,3,3,6;

[0094] The calculation process of performing CRC8 check after encryption:

[0095] Formula 1: T(x) = f(x)*2 k +R(x),

[0096] Formula 2: R(x) = f(x)*2 k / G(x)

[0097] In the above formula, T(x) represents the sending code, R(x) represents the check code, f(x) represents the data to be transmitted, G(x) represents the polynomial agreed upon by the sender and receiver, and k is equal to the length of G(x) minus 1.

[0098] For example, if the transmitted data f(x) is 0x92, converted to binary 101001, then f(x) = 101001, and the polynomial convention is G(x) = X 3 +X 2 +X 0 , expressed in binary G(x) = 1101, length is 4

[0099] k is equal to the length of G(x) minus 1, then k = 3;

[0100] In the formula, f(x)*2 k =101001*2 3 =101001000

[0101] R(x)=f(x)*2 k / G(x)=101001000 / 1101, take the remainder 3 digits 001

[0102] T(x)=f(x)*2 k +R(x)=101001001

[0103] When the receiving end divides the received data by G(x), if the remainder is 0, it means the received data is correct, otherwise it is wrong.

[0104] The BASE16 encryption algorithm converts the data into corresponding binary numbers;

[0105] Then string all the binary numbers together, with 4 binary bits as a group, and convert them into the corresponding decimal numbers;

[0106] Find the corresponding character in the Base16 encoding table according to the decimal value;

[0107] The base is 4 bits to represent one character, and the original code is one byte (8 bits) to represent one character, which means that if one character is encoded using ASCII, it will now be converted into two characters. The data volume is twice as much as before. See the following table:

[0108]

[0109] The CRC8 verification process is as follows:

[0110] Set an 8-bit register to 0

[0111] XOR the byte with the highest bit of the register; shift the register left by one bit; if the XOR result is 1, XOR the register with a predefined polynomial

[0112] Repeat the above byte processing process until all bytes are processed

[0113] The final value in the register is the CRC check code.

[0114] S102: Send the ciphertext file to the signal source through the network port of the upper computer that sends the ciphertext;

[0115] The specific design process of sending the ciphertext to the host computer is as follows: First, design the ciphertext host computer UI interface, as follows Figure 5 , add a network port connection interface. After the interface is connected to the signal source, select the ciphertext file and send it to the signal source.

[0116] S103: The signal source parses the ciphertext file, sets new signal permissions according to the analysis, inputs the new signal permissions into the signal source host computer, reads the signal permissions and displays the open signals for users to use.

[0117] The signal source parses the ciphertext file:

[0118] The signal source receives the ciphertext file through the network port, and then performs a CRC8 check. After the check passes, it starts to use the BASE16 decryption algorithm to decrypt the product serial number, the option signal permission variable, and the key to obtain a mixed value. The product serial number is extracted from the mixed value and compared with the signal source serial number. After the comparison is successful, the option signal permission variable is extracted from the mixed value using the key and stored in the chip. Finally, the signal is selected whether to be open based on the option signal permission variable.

[0119] Embodiment 2: In the second aspect, as Figure 6 As shown, in order to achieve the above-mentioned purpose, the present invention discloses a system for setting signal permissions of a signal source through software, comprising:

[0120] The ciphertext generation module 11 is used to receive the setting signal authority, input the setting signal authority into the ciphertext generation host computer, and output the ciphertext file;

[0121] The ciphertext transmission module 12 is used to send the ciphertext file to the signal source through the ciphertext upper computer using the network port;

[0122] The ciphertext parsing module 13 is used for the signal source to parse the ciphertext file, set new signal permissions according to the analysis, input the new signal permissions into the signal source host computer, read the signal permissions and display the open signals for users to use.

[0123] In conjunction with the second aspect, in some implementations of the second aspect, the system further includes: the ciphertext generation module 11 inputs the set signal authority into the ciphertext generation host computer, and outputs a process of obtaining a ciphertext file:

[0124] Generate ciphertext The host computer mixes the product serial number, option signal permission variable, and key, and encrypts them using the BASE16 encryption algorithm. After encryption, it performs a CRC8 check to finally generate a ciphertext file.

[0125] The calculation process of encryption using the BASE16 encryption algorithm:

[0126] For example, if the sent data is 3,6, according to the ASCII table, the ASCII value of 3 is 51, and the ASCII value of 6 is 54;

[0127] 51 is converted to binary 00110011, the high four bits are 3 (decimal), the low four bits are 2 (decimal)

[0128] 54 is converted to binary 00110110, the high four bits are 3 (decimal), the low four bits are 6 (decimal)

[0129] Finally, the data obtained by BASE16 encrypting 3,6 is 3,3,3,6

[0130] The calculation process of CRC8 check after encryption:

[0131] Formula 1: T(x) = f(x)*2 k +R(x),

[0132] Formula 2: R(x) = f(x)*2 k / G(x)

[0133] In the above formula, T(x) represents the sending code, R(x) represents the check code, f(x) represents the data to be transmitted, G(x) represents the polynomial agreed upon by the sender and receiver, and k is equal to the length of G(x) minus 1.

[0134] For example, if the transmitted data f(x) is 0x92, converted to binary 101001, then f(x) = 101001, and the polynomial convention is G(x) = X 3 +X 2 +X 0 , expressed in binary G(x) = 1101, length is 4

[0135] k is equal to the length of G(x) minus 1, then k = 3;

[0136] In the formula, f(x)*2 k =101001*2 3 =101001000

[0137] R(x)=f(x)*2 k / G(x)=101001000 / 1101, take the remainder 3 digits 001

[0138] T(x)=f(x)*2 k +R(x)=101001001

[0139] When the receiving end divides the received data by G(x), if the remainder is 0, it means the received data is correct, otherwise it is wrong.

[0140] The BASE16 encryption algorithm converts the data into corresponding binary numbers;

[0141] Then string all the binary numbers together, with 4 binary bits as a group, and convert them into the corresponding decimal numbers;

[0142] Find the corresponding character in the Base16 encoding table according to the decimal value;

[0143] The CRC8 verification process is as follows:

[0144] Set an 8-bit register to 0

[0145] XOR the byte with the highest bit of the register; shift the register left by one bit; if the XOR result is 1, XOR the register with a predefined polynomial

[0146] Repeat the above byte processing process until all bytes are processed;

[0147] The final value in the register is the CRC check code;

[0148] The process of the signal source in the ciphertext parsing module 13 parsing the ciphertext file:

[0149] The signal source receives the ciphertext file through the network port, and then performs a CRC8 check. After the check passes, it starts to use the BASE16 decryption algorithm to decrypt the product serial number, the option signal permission variable, and the key to obtain a mixed value. The product serial number is extracted from the mixed value and compared with the signal source serial number. After the comparison is successful, the option signal permission variable is extracted from the mixed value using the key and stored in the chip. Finally, the signal is selected whether to be open based on the option signal permission variable.

[0150] The example operation is as follows

[0151] like Figure 7 As shown, the SSB and DSB options are disabled ( Figure 7 SSB, DSB are not displayed), LFM (Linear Frequency Modulation) and CW options are enabled ( Figure 7 Display LFM, CW)

[0152] like Figure 8 As shown, input the signal source module serial number 410222070121, change the option permissions (SSB and DSB option permissions are turned on, LFM and CW option permissions are turned off, and the UC, FH, BBG, and BW option permission statuses are not changed), click "Generate Ciphertext" to generate a 47-bit ciphertext, and a file save interface will pop up, save it to the path you want.

[0153] like Fig. 9 As shown in the figure, use the option setting tool to send the file to the signal source module. The specific operations are as follows:

[0154] Connecting devices

[0155] Select a previously saved sequence file

[0156] Click to confirm the release

[0157] Signal source module restart

[0158] After setting permissions, such as Fig.10 As shown, the SSB and DSB options are turned on ( Fig.10 Display SSB, DSB), LFM (Linear Frequency Modulation) and CW option permissions are turned off ( Fig.10 Linear frequency modulation (LFM, CW) is not displayed, and the permission status of UC, FH, BBG, and BW options is not changed.
