Detailed Description
The technical scheme of the invention is further elaborated by combining the drawings and the specific embodiments in the specification. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, an activate code generation method provided for an embodiment of the present invention can be applied to an activate code generation apparatus, where the activate code generation apparatus is configured to generate an activate code, and includes the following steps:
step S101: acquiring a vehicle identification code of a vehicle, a product serial number of a vehicle machine and an international mobile subscriber identification code;
it should be noted that, when the activation code generation apparatus is applied to a car machine, the acquiring a vehicle identification code of a vehicle, a product serial number of the car machine, and an international mobile subscriber identity includes:
receiving an activation request instruction for activating a vehicle machine;
and responding to the activation request instruction, and acquiring a vehicle identification code of the vehicle, the product serial number of the vehicle machine and the international mobile subscriber identification code.
It can be understood that the receiving of the activation request instruction for activating the car machine may be receiving an operation of a user for activating the car machine through an operation body such as a finger or a stylus pen, for example, detecting that a car machine activation virtual key displayed on a car machine interface is triggered. The vehicle identification code of the vehicle is unique identification information of the vehicle, the product serial number of the vehicle machine is serial number information of a manufacturer of the vehicle machine to the vehicle machine, the international mobile Subscriber Identity is stored in a Subscriber Identity Module (SIM), also called a SIM card, and the SIM card is arranged in a communication Module in the vehicle machine or in a vehicle-mounted T-box (telematics box) bound with the vehicle machine.
It should be noted that, when the activation code generating apparatus is applied to a remote Service Provider (TSP) server of an automobile, the acquiring a vehicle identification code of the vehicle, a product serial number of the vehicle machine, and an international mobile subscriber identification code includes:
receiving an activation code acquisition request which is sent by a vehicle machine and used for requesting to acquire an activation code; the activation code acquisition request carries a vehicle identification code of the vehicle, a product serial number of the vehicle machine and an international mobile subscriber identification code.
Here, when it is determined that the car machine needs to be activated, the car machine may send an activation code acquisition request to the TSP server, and the activation code generation device receives the activation code acquisition request sent by the car machine to request to acquire an activation code, generates a corresponding activation code according to a vehicle identification code of a vehicle, a product serial number of the car machine, and an international mobile subscriber identification code, which are carried in the activation code acquisition request, and returns the activation code to the car machine, so that the car machine activates the car machine according to the activation code returned by the TSP server.
Step S102: the vehicle identification code of the vehicle, the product serial number of the vehicle machine and the international mobile subscriber identification code are subjected to permutation and combination to obtain a target character string generated after permutation and combination;
it can be understood that the vehicle identification code of the vehicle, the product serial number of the vehicle machine, and the international mobile subscriber identity are each a character string, and when the vehicle identification code of the vehicle, the product serial number of the vehicle machine, and the international mobile subscriber identity are arranged and combined, a plurality of arrangement combinations are generated according to different arrangement positions of each character string, that is, a plurality of target character strings are generated after the arrangement combinations. According to the known permutation and combination principle, the vehicle identification code of the vehicle, the product serial number of the vehicle end and the international mobile subscriber identity are permutated and combined, so that six different target character strings can be generated. In this embodiment, a character string obtained by sequentially arranging the vehicle identification code of the vehicle, the international mobile subscriber identification code, and the product serial number of the in-vehicle device from front to back is taken as an example of the target character string.
Step S103: and generating an activation code according to a set activation code generation mode based on the target character string.
The activation code generation mode is used for correspondingly generating the activation code by performing operations such as encryption on the target character string, so that the activation code is generated according to the bound vehicle identification code of the vehicle, the international mobile subscriber identification code and the product serial number of the vehicle machine. In practical application, the activation code generation mode can be set according to actual needs. The principle of generating the activation code according to the set activation code generation mode based on the target character string comprises the following steps: the method comprises the steps of selecting one of a vehicle identification code of a vehicle, an international mobile subscriber identification code and a product serial number of a vehicle machine as required to be encrypted to generate a key character string, encrypting a target character string to generate a plaintext character string, generating a ciphertext character string according to the key character string and the plaintext character string, and finally obtaining an activation code according to the ciphertext character string, so that the activation code is more complex, and the cracking difficulty of the activation code is increased.
In summary, the activation code generation method, the activation code generation device, and the computer storage medium provided in the above embodiments obtain the vehicle identification code of the vehicle, the product serial number of the vehicle machine, and the international mobile subscriber identity; the vehicle identification code of the vehicle, the product serial number of the vehicle machine and the international mobile subscriber identification code are subjected to permutation and combination to obtain a target character string generated after permutation and combination; and generating an activation code according to a set activation code generation mode based on the target character string. So, bind and generate corresponding activation code through the vehicle identification code with the vehicle, the product serial number and the international mobile subscriber identity of car machine, increased the degree of difficulty that explains of activation code to the security of activation code has effectively been improved.
In an embodiment, the generating an activation code according to a set activation code generation manner based on the target character string includes:
determining a first character string, and acquiring a second character string matched with the last character of the first character string according to the corresponding relation between the last character of the first character string and the second character string set by the last character query of the first character string; the first character string and the second character string are respectively one of the following character strings: the vehicle identification code of the vehicle, the product serial number of the vehicle machine and the international mobile subscriber identification code;
encrypting the second character string and the target character string according to a set encryption algorithm to generate a ciphertext character string;
and extracting characters of the ciphertext character string, and acquiring the character string matched with the set length value as an activation code.
It can be understood that the corresponding relationship between the last character of the first character string and the second character string may be set according to actual needs, and when the first character string changes, the second character string corresponding to the last character of the first character string may also change correspondingly. In an embodiment, the obtaining, according to a correspondence between a last character of the first character string and a second character string set by a last character query of the first character string, the second character string matched with the last character of the first character string includes: when the last character of the product serial number of the vehicle machine is an even number, the second character string is a vehicle identification code of the vehicle; and when the last character of the product serial number of the car machine is an odd number, if the last character of the product serial number of the car machine is a multiple of 3, the second character string is the international mobile subscriber identity, otherwise, the second character string is the product serial number of the car machine. For example, if the first character string is the product serial number of the car machine and the product serial number of the car machine is P007001100000311, since the last character of the product serial number of the car machine is 1, which is odd and not a multiple of 3, the second character string is the product serial number of the car machine. Therefore, the flexibility of the activation code is improved by flexibly setting the relative relationship between the first character string and the second character string.
It is understood that the encryption algorithm may be set according to actual requirements, and the ciphertext character string is usually obtained by encrypting the key character string and the plaintext character string through the encryption algorithm. In an embodiment, the encrypting the second character string and the target character string according to a set encryption algorithm to generate a ciphertext character string includes: carrying out encryption operation on the second character string according to a set message digest algorithm to generate a key character string; carrying out encryption operation on the target character string according to a set message digest algorithm to generate a plaintext character string; and encrypting the key character string and the plaintext character string according to a set advanced encryption standard algorithm to generate a ciphertext character string. Therefore, the character string encrypted by the message digest algorithm cannot be decrypted, so that the safety of the ciphertext character string can be ensured, and the safety of the activation code is further improved.
It should be noted that, the extracting of the characters from the ciphertext character string, and acquiring the character string matching the set length value as the activation code, may be extracting all the characters constituting the activation code from the ciphertext character string, or extracting a part of the characters constituting the activation code from the ciphertext character string, and generating the other part according to the current date and other factors.
In an embodiment, the extracting the characters of the ciphertext character string and acquiring the character string matched with the set length value as an activation code includes:
and sequentially selecting the character strings with the length of the set length value from the first character of the ciphertext character string as the activation codes.
Here, the length value may be set according to actual requirements, for example, may be set to a 16-bit hexadecimal number. For example, assuming that the ciphertext string is a hexadecimal representation of the string 218D 25019410C 98 CA 14C 4D 74 CE FF D4 CD, if the length value is a 16-bit hexadecimal number, the activate code is 218D 25019410C 98C. Therefore, the activation code is directly selected from the ciphertext character string, and the method is simple and quick.
In an embodiment, the extracting the characters of the ciphertext character string and acquiring the character string matched with the set length value as an activation code includes:
sequentially selecting character strings with a set first length value from a first character of the ciphertext character string as a first activation code sub-string;
generating a character string with a length of a set second length value as a second activation code sub-string according to a difference value between the current date and the set date value;
and carrying out permutation and combination on the first activation code substring and the second activation code substring according to the set permutation and combination sequence to generate the activation codes.
Here, the first length value and the second length value may be set according to actual needs, for example, the first length value may be set to be a 12-bit hexadecimal number, the second length value may be set to be a 4-bit hexadecimal number, and the like. The date value can be set according to actual situation requirements, for example, the date value can be set to the production date of the vehicle machine. It should be noted that the difference between the current date and the set date value is the number of days that the current date and the set date value are different from each other. The first activation code substring and the second activation code substring are arranged and combined according to the arranged arrangement and combination sequence, and two different arrangement and combination sequences exist. For example, assuming that the ciphertext string is a hexadecimal string 218D 25019410C 98C a 14C 4D 74 CE FF D4 CD, the current date is 29 days 11 months in 2018, the set date value is 1 day 8 months in 2018, the first length value is a 12-bit hexadecimal number and the second length value is a 4-bit hexadecimal number, the first activation code substring is 218D 25019410, and since the difference between the current date and the set date threshold is 120 days, the activation code is represented as a 4-bit hexadecimal number 0078 in hexadecimal, the activation code is represented as 0078218D 25019410. Since the difference between the current date and the set date value is included in the activation code, the current date can be known from the activation code given the set date value, and the current date is considered to be the date of generation of the activation code. Because the activation code is used for activating the car machine, the activation date of the car machine can be known according to the activation code.
Therefore, the activation code is generated according to the difference value between the current date and the set date value, so that the generation date of the activation code, namely the activation date of the car machine can be known according to the activation code.
In an embodiment, the performing permutation and combination on the first activate code sub-string and the second activate code sub-string according to the set permutation and combination order to generate the activate code includes:
and carrying out permutation and combination on the first activation code substring, the second activation code substring and a third activation code substring according to the set permutation and combination sequence to generate an activation code, wherein the third activation code substring is a random character string with a length of a set third length value.
When the first, second and third activate code sub-strings are arranged and combined, a plurality of kinds of arrangement combinations, that is, a plurality of kinds of activate codes generated after the arrangement and combination, are generated according to different positions of each character string arrangement. In this embodiment, a character string obtained by sequentially arranging the second activation code sub-string, the first activation code sub-string, and the third activation code sub-string from front to back is taken as an example of the activation code. Under the condition that the length of the active code is fixed, the third length value needs to be determined according to the first length value and the second length value, for example, the first length value may be set to be a 10-bit hexadecimal number, the second length value may be set to be a 4-bit hexadecimal number, and the third length value may be set to be a 2-bit hexadecimal number. For example, assuming that the ciphertext string is a hexadecimal string 218D 25019410C 98C a 14C 4D 74 CE FF D4 CD, the current date is 29 days 11 months in 2018, the set date value is 1 day 8 months in 2018, the first length value is a 12-bit hexadecimal number, the second length value is a 4-bit hexadecimal number, and the third length value is a 2-bit hexadecimal number, the first activation code substring is 218D 250194, and since the difference between the current date and the set date threshold is 120 days, it is represented as a 4-bit hexadecimal number 0078 in hexadecimal; when the random string is AB, the activation code may be represented as 0078218D 250194 AB.
Therefore, the flexibility of the activation code is enhanced by adding the random character string into the activation code, and the safety of the activation code is further improved.
When the activation code generation apparatus is applied to a TSP server, after generating an activation code in a set activation code generation manner based on the target character string, the activation code generation apparatus may further include:
and sending a response message carrying the activation code to be verified to the vehicle machine.
The activation code generation device generates a corresponding activation code according to the vehicle identification code carrying the vehicle, the product serial number of the vehicle machine and the international mobile subscriber identification code, which are sent by the vehicle machine, and then sends the activation code to the vehicle machine, so that the vehicle machine can activate the vehicle machine in time according to the activation code.
It should be noted that, when the activation code generation apparatus is applied to a car machine, after acquiring a vehicle identification code of a vehicle, a product serial number of the car machine, and an international mobile subscriber identity, the method may further include:
sending an activation code acquisition request for requesting to acquire an activation code to an automobile remote service provider server; the activation code acquisition request carries a vehicle identification code of the vehicle, a product serial number of the vehicle machine and the international mobile subscriber identification code;
receiving a response message which is returned by the automobile remote service provider server based on the activation code acquisition request and carries an activation code to be verified;
and verifying the activation code to be verified according to the activation code generated by the activation code generation device, and activating the car machine when the verification is passed.
It can be understood that, in order to activate a car machine, an activation code for activating the car machine needs to be acquired from a car remote service provider server, so an activation code acquisition request for requesting to acquire the activation code needs to be sent to the car remote service provider server, and an activation code to be verified returned by the car remote service provider server based on the activation code acquisition request is received, and then the activation code to be verified is verified according to the activation code generated at the car machine end, so that the car machine is activated when the verification passes. The activation code generated by the vehicle end is an activation code generated by an activation code generation device applied to the vehicle.
Here, the verification of the to-be-verified activation code according to the activation code generated by the activation code generation device may be to verify whether the activation code generated by the vehicle end is consistent with the to-be-verified activation code, and if so, the verification is passed, otherwise, the verification is not passed. It should be noted that the activation code generated by the vehicle end and the activation code to be verified may be any one of the following cases: when the activation code is a character string which is extracted from the ciphertext character string in sequence and has a length value set, detecting that the activation code generated by the vehicle terminal is the same as the activation code to be verified; when the activation code consists of the first activation code substring and the second activation code substring, detecting that the activation code generated by the vehicle end is the same as the activation code to be verified; when the activation code is composed of the first activation code substring, the second activation code substring and the third activation code substring, it is detected that the activation code generated by the vehicle end is the same as the part of the to-be-verified activation code composed of the first activation code substring and the second activation code substring, and the part of the to-be-verified activation code composed of the third activation code substring may be different.
Therefore, the car machine is activated according to the activation code which is generated correspondingly by binding the car identification code of the car, the product serial number of the car machine and the international mobile subscriber identification code, and the legal use of the car machine by the user is further ensured.

Step S207: and after the verification of the activation code sent by the TSP server is passed, the vehicle machine is activated.
The car machine generates an activation code according to the vehicle identification code of the vehicle, the product serial number of the car machine and the international mobile subscriber identification code, verifies the activation code sent by the TSP server by using the activation code, and activates the car machine when the verification is passed.
As described above, the activation code generation method provided by the above embodiment may process the binding relationship between the in-vehicle device, the vehicle, and the SIM card to obtain the activation code, and is applicable to the external T-BOX scheme and the SIM card integrated in the in-vehicle device.
The generation process of the activation code is specifically described below by using a specific example, and the format of the activation code, the adopted encryption algorithm, and the like are firstly limited. The activate code is a 16-bit string consisting of 0-F hexadecimal characters. The encryption algorithm adopts an advanced encryption standard algorithm, and the mode is ECB. When the last bit of the PDSN is 0/2/4/8, a character string generated after performing MD5 operation on the VIN is used as a key; when the last digit of the PDSN is 3/6/9, a character string generated after MD5 operation is carried out on the IMSI is used as a key; when the last digit of the PDSN is 1/4/7, a string generated after MD5 operation is performed on the PDSN is used as a key. And a character string generated by performing MD5 operation on the VIN, the IMSI and the PDSN which are sequentially arranged is used as a ciphertext. The first 5 bytes in the ciphertext expressed in hexadecimal form a 10-bit string, which is marked as a string A. The number of days from the set date to the current date is represented by a 4-bit hexadecimal number, and is denoted as a character string B. The 4-bit character of the character string B is placed together in the character string A to form a 14-bit character string, for example, the character string B is placed in front of the character string A, and finally a 2-bit hexadecimal random character string is added, for example, placed at the end of the character string formed by the character string A, B.
Assuming that VIN is LSJW26792CS990006, IMSI is 460011418603055, and PDSN is P007001100000311, the string formed by arranging VIN, IMSI, and PDSN in sequence is LSJW26792CS990006460011418603055P007001100000311, the plaintext is the string 36CBBD057B0B80A0BBB02E7EF37B3F57 generated by performing MD5 operation on the string, and since the last bit of PDSN is 1, the key uses the string 490BF05E3CF51B4AE3E00FBC895C1ED0 generated by performing MD5 operation on PDSN. The cipher text obtained by encrypting the plaintext by the key through an AES algorithm is 218D 25019410C 98C A14C 4D 74 CE FF D4 CD, the first 5 bytes 218D 250194 of the cipher text are taken as a character string A, the current date is 11/29/2018, the number of days from 8/1/2018 to the present is represented by 0078 in hexadecimal form and is taken as a character string B, and finally a random character string consisting of CDs is placed at the tail of the character string A and the character string B, so that the generated activation code is 0078218D 250194 CD.
