Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The software can provide two deployment schemes of cloud and localization, so that the software authorization can be divided into online authorization and offline authorization. Cloud-deployed services generally provide online authorization. Whereas for locally deployed software, offline authorization is typically provided.
Software with intellectual property generally takes the form of software protection, which requires some means to activate the software before it can be used. The software activation essence is to compare the ciphertext data, which is generally generated by the software developer through encryption according to the feature data of the target machine. The activation process is done on the authentication server or the target machine.
Currently, the mainstream offline authorization scheme basically generates an MD5 value based on the characteristics of the server, and encrypts the MD5 value again to obtain authorization information. The software is activated offline using the authorization information. The characteristics of the server may include one or more of a Mac address, a hard disk serial number, and a cpu serial number.
The MD5 value is a parameter obtained by an MD5 algorithm. The MD5 Algorithm is the MD5 Messag e-Digest Algorithm message Digest Algorithm, a widely used cryptographic hash function. The Media Access Control (Mac) Address is the physical Address of the device. The MAC address is used to uniquely identify a network card in the network, and if one or more network cards exist in a device, each network card needs to have a unique MAC address.
Referring to fig. 1, fig. 1 is a schematic diagram of a process of server-based feature authorization verification in the prior art, which is illustrated by taking a machine feature as a Mac address and an encryption algorithm as a DES feature, and specifically includes:
s101, a Mac address of the server is obtained, and an MD5 value is generated according to the obtained Mac address.
S102, the MD5 value is encrypted, and an authorization code or an authorization file presence.
And S103, sending authorization information to the client, and inputting an authorization code in software or uploading an authorization file presence.
And S104, the software analyzes the authorization code or the authorization file, and the MD5 value is obtained after decryption.
S105, comparing the MD5 values.
And the software acquires the Mac address of the current running server and generates an MD5 value. And comparing the MD5 values of S104 and S105, and if the MD5 values are consistent, successfully activating the software system. Otherwise, it fails.
Among them, the Data Encryption Standard (DES) is a block algorithm using key Encryption.
In the solution of fig. 1, the following problems exist: the software can be used all the time after one-time authorization, and the use time of the software cannot be limited; the authorization information may be multiplexed. Such as: by modifying the mac addresses of other servers to existing mac addresses, software on multiple servers can be activated with one copy of authorization information.
It can be seen that the authorization information is generated based on the characteristics of the server, and the illegal use of the software cannot be limited.
In order to solve the technical problem that the illegal use of the software cannot be limited, the following technical scheme in the embodiment of the invention can be adopted.
Referring to fig. 2, fig. 2 is a schematic diagram of a main flow of an authorization verification method according to an embodiment of the present invention, in which a user is verified through a user identifier in a user authorization code, and a valid date is verified through an authorization code validity period in the user authorization code, so as to limit illegal use of software. As shown in fig. 2, the method specifically includes the following steps:
s201, decrypting the user authorization code by using the public key to obtain an encrypted authorization code.
In the embodiment of the invention, two ends, namely a server end and a client end, are involved. The server can be arranged in a server for developing software, and the client is arranged in a server for using software.
Referring to fig. 3, fig. 3 is a schematic view of a usage scenario of a method for verifying application authorization according to an embodiment of the present invention, specifically including a server and two clients.
The server is used for generating a user authorization password aiming at the user. The server side can send the generated user authorization password to the user. As an example, the server sends the user authorization code to the user through an e-mail or the like. After receiving the user authorization code, the user can input the user authorization code at the client. If the user authorization password is successfully verified, the software can be continuously used; if the user authorization password fails to be verified, the software cannot be used continuously after the actual use days.
It is understood that the execution subject of each step in fig. 2 is a client.
In order to avoid revealing the authorization information, the user authorization code is data encrypted by the server. The client needs to decrypt the user authorization code to obtain the authorization information.
In the embodiment of the invention, the user authorization code is decrypted in two steps. The first step is decryption with a public key and the second step is decryption with a user key. The public key is preset in the software, and the user secret key is preset in the user authorization code.
Referring to fig. 4, fig. 4 is a schematic diagram of decrypting the user authorization code according to the embodiment of the present invention, where the client, upon receiving the user authorization code, may decrypt the user authorization code by using the public key and the DES to obtain the encrypted authorization code. In one embodiment of the invention, the user authorization code may be user-entered.
That is, a public key is preset in software, and a user of the public key decrypts the user authorization code to obtain the encrypted authorization code.
S202, based on the user secret key obtained from the encrypted authorization code, the original authorization code in the encrypted authorization code is decrypted, and the user identifier, the validity period of the authorization code and the number of authorized use days are obtained.
The encrypted authorization code includes a user key and an original authorization code, and the original authorization code can be decrypted by using the user key.
Referring to fig. 5, fig. 5 is a schematic flowchart of decrypting an original authorization code according to an embodiment of the present invention, which specifically includes:
s501, acquiring a user secret key and an original authorization code from the encrypted authorization code through preset characters in the encrypted authorization code.
In the encrypted authorization code, the user key and the original authorization code are divided into predetermined characters. Then, by identifying the preset characters in the encrypted authorization code, the user key and the original authorization code can be obtained from the encrypted authorization code.
In the embodiment of the present invention, in order to quickly obtain the user key and the original authorization code, the preset characters include preset special characters. I.e. the user key and the original authorization are split up with preset special characters. Such as: the preset special characters are: #. Of course, other special characters are possible.
S502, based on the user secret key, the original authorization code in the encrypted authorization code is decrypted to obtain the user identification, the validity period of the authorization code and the number of authorized use days.
According to the user secret key, the original authorization code in the encrypted authorization code is decrypted, and then the user identification, the validity period of the authorization code and the number of authorized use days can be obtained.
Referring to fig. 6, fig. 6 is a schematic diagram of decrypting an original authorization code according to an embodiment of the present invention, which specifically includes: by using the user key, the original authorization code in the encrypted authorization code is decrypted, and the user identifier, the validity period of the authorization code and the number of authorized use days can be obtained.
Referring to fig. 7, fig. 7 is a schematic flowchart of decrypting an original authorization code according to an embodiment of the present invention, which specifically includes the following steps:
s701, decrypting the original authorization code in the encrypted authorization codes to obtain the splicing authorization code.
And decrypting the original authorization code in the encrypted authorization code by combining the user secret key with DEC to obtain the splicing authorization code.
In the embodiment of the invention, the splicing authorization code is formed by splicing the user identification, the validity period of the authorization code and the authorized use days. And the preset characters are divided among the user identification, the validity period of the authorization code and the number of authorized use days.
S702, segmenting the splicing authorization code according to preset characters in the splicing authorization code to obtain the user identification, the authorization code validity period and the authorized use days.
Since the user identifier, the validity period of the authorization code and the number of authorized use days are divided by the preset characters, the splicing authorization code can be divided according to the preset characters in the splicing authorization code, and the user identifier, the validity period of the authorization code and the number of authorized use days are obtained.
In the embodiment of the invention, in order to quickly acquire the user identifier, the validity period of the authorization code and the authorization use days, the preset characters comprise preset special characters. I.e. the user key and the original authorization are split up with preset special characters. Such as: the preset special characters are: #. Of course, other special characters are possible.
As an example, the splice authorization code is: t1# YYYYMMDD # D1. And dividing the splicing authorization code according to the preset character # to obtain T1, YYYYMMDD and D1, a user number T1, an authorization code validity period YYYYYMMDD and an authorized use number of days D1.
In the embodiment of fig. 7, the splicing authorization code includes not only the user identifier, but also an authorization code validity period and an authorization use number of days, and may be segmented according to preset characters in the splicing authorization code.
In the embodiment of fig. 5, the user identifier, the validity period of the authorization code, and the number of authorized use days are obtained by encrypting the authorization code, on one hand, the extractable information is ensured by using the preset characters, and on the other hand, the original authorization code is decrypted by using the user key, so as to ensure the security of the original authorization code.
S203, if the user identifier obtained by decryption is consistent with the actual user identifier and the current date does not exceed the validity period of the authorization code, updating the actual use days of the software through the authorization use days.
The client is preset with user identification and actual use days of the software. As an example, in order to secure the user identification and the actual number of days of use of the software, illegal modification of the above information is avoided. The actual user identification and the actual use days of the software are stored in the client after being encrypted by the public key. And in the process of authorization verification, decrypting by using the public key to obtain the actual user identification and the actual use days of the software.
TABLE 2
| User identification | Number of days of actual use |
| T1 | D＝0 |
Referring to table 2, table 2 is a table in which the client stores the user identification and the actual number of days of use. Table 2 may be encrypted by a public key.
And if the decrypted user identifier is consistent with the actual user identifier, the user authorization code is specific to the user and not specific to other users. And if the user identifier obtained by decryption is not consistent with the actual user identifier, indicating that the user authorization code is specific to other users, and displaying that decryption fails.
If the current date does not exceed the validity period of the authorization code, the user authorization code is valid; if the current date exceeds the validity period of the authorization code, the user authorization code is invalid, and the decryption is over-term.
As an example, the current date is 4 days 2/2020, the authorization code validity period is 8 days 2/2020, the current date does not exceed the authorization code validity period, and the user authorization code is valid.
As another example, the current date is 9/2/2020, the authorization code validity period is 8/2/2020, the current date exceeds the authorization code validity period, the user authorization code expires, and the decryption expiration period is displayed.
Referring to fig. 8, fig. 8 is a schematic flowchart of a lifetime of updated software according to an embodiment of the present invention, which specifically includes:
s801, the configuration file is decrypted by using the public key to obtain the actual user identification and the service life of the software.
In order to avoid illegal modification of the user identification and the actual number of days of use of the software, the user identification and the actual number of days of use of the software may be stored in a configuration file and encrypted with a public key. As one example, the configuration file may be table 2 above.
When the service life of the software needs to be updated, the configuration file can be decrypted by using the public key to obtain the actual user identification and the service life of the software.
S802, if the user identification obtained by decryption is consistent with the actual user identification and the current date does not exceed the validity period of the authorization code, the number of authorized use days is increased on the actual use days of the software.
And if the decrypted user identifier is consistent with the actual user identifier and the current date does not exceed the validity period of the authorization code, the user authorization code is valid, and the number of authorization use days is increased in the actual number of use days of the software.
As an example, the actual usage days of the software is 2 days, the user authorization code is valid, the authorized usage days are 30 days, and the actual usage days of the updated software is 32 days.
In the embodiment of fig. 8, the actual number of days of use of the software may be updated by the number of days of authorized use in the event that the user authorization code is valid.
In one embodiment of the invention, the actual number of days of use of the software is updated over time. As one example, the actual number of days of use of the software is updated at least once per day. Such as: and automatically updating the actual use days D in the configuration file at 24 points every day, executing D-1, and storing by adopting public key encryption.
In one embodiment of the invention, the number of actual usage days of the software is extended in order to remind the user to obtain the user authorization code again. And when the actual use days of the software are less than or equal to the reminding days, sending a reminding message.
As an example, if the number of days of reminder is 20 and the number of actual use days of the software is 19, a reminder message is sent to the user.
In one embodiment of the invention, if the number of actual use days of the software is equal to zero, the service of the software is stopped, and the user authorization code is waited to be input.
The above is the actual number of days of the user who receives the user authorization code from the client to update the software, and illustrates the technical scheme in the embodiment of the present invention.
The following describes a specific technical scheme for establishing the user authorization code from the perspective of the server.
