Detailed Description
Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the embodiments of the present application and are not to be construed as limiting the embodiments of the present application.
Referring to fig. 1 and 2, an embodiment of the present application provides an encryption method, including:
step 011: under the condition that a request for storing original data is received, reading key information stored in the encryption lock 100, wherein the original data is data generated by target software authorized by the encryption lock 100;
specifically, the encryption lock is an intelligent tool with a software protection function provided for a software developer, and can be used for preventing corresponding software from being illegally used. The original data is data generated by the target software authorized by the dongle 100. The existing encryption lock 100 only encrypts the software, and can open the software as long as the encryption lock 100 is authorized by the software, so as to attempt to access all original data in the software, so that the security of the original data is lower, the original data is easily copied randomly in the software, the situation of being stolen occurs, and the original data has poor controllability and cannot be managed and controlled. For a software developer writing original data, after the original data is released in one piece of software, the original data may be copied and used by an unauthorized machine, so that normal revenue is affected, and economic loss is caused.
In order to solve the problems, the original data is encrypted, so that the safety and the controllability of the original data are improved. First, when original data has been generated and needs to be saved, that is, when a request for saving the original data is received, key information stored in the encryption lock 100 is read so as to encrypt the original data according to the key information.
Step 012: the original data is encrypted according to the key information to generate encrypted data.
Specifically, after the key information of the encryption lock 100 is acquired, the original data may be encrypted according to the key information to generate encrypted data. Thus, the encryption of the original data is completed, so that other encryption locks 100 authorized by the target software cannot unlock the encrypted data to acquire the original data, thereby improving the security and controllability of the original data.
Further, when the original data is encrypted according to the key information, the original data is changed from an unencrypted state to an encrypted state by writing the key information into the original data. The original data written with the key information is then saved to generate encrypted data. Thus, the encryption of the original data can be completed through the key information, and only the encryption lock 100 with the key information consistent with the key information in the original data can unlock the encrypted data, so that the staff can use the original data.
In the encryption method of the embodiment of the present application, when a request for storing original data is received, key information stored in the encryption lock 100 is read, so that targeted encryption of the original data is completed, and then the original data is encrypted according to the key information to generate encrypted data, so that the original data cannot be easily leaked. Thus, compared to the encryption technology that can only encrypt software, the encryption lock 100 can be utilized to encrypt the original data, so as to reduce the risk of the original data being stolen in the software, thereby increasing the security of the original data.
Referring to fig. 2 and 3, in some embodiments, the encryption method further includes:
step 013: writing information of the target software and key information into a storage space of the encryption lock 100;
step 014: in the case where the information of the target software in the storage space matches the target software, the target software is authorized to read and write the encryption lock 100.
Specifically, the encryption lock 100 has a certain storage space inside, which can be used to store information and key information of the target software, and the encryption lock 100 can only obtain authorization of the software stored with the corresponding information in the storage space. In order to increase the security of the target software, some target software may also be subject to encryption, so that the encryption lock 100 also needs to obtain authorization of the target software. When the encryption lock 100 unlocks a piece of encrypted data, if the target software where the encrypted data is located also presents an encrypted state, the encryption lock 100 needs to obtain authorization of the target software and the encrypted data at the same time, otherwise, the encryption lock 100 cannot unlock the target software, and further the unlocking of the encrypted data is completed.
Therefore, the information of the target software and the key information need to be written into the storage space of the encryption lock 100 at this time, so that subsequent authorization verification is facilitated. When the target software needs to be used, the encryption lock 100 can be used, then the target software can acquire the information of the target software in the storage space of the encryption lock 100, and under the condition that the information of the target software in the storage space is matched with the target software, the read-write permission of the target software to the encryption lock 100 is authorized, and at the moment, the target software can be started to be used. Thus, the target software can be unlocked by using the encryption lock 100, and the unauthorized encryption lock 100 can not open the target software, so that the controllability and the security of the target software can be improved conveniently.
Referring to fig. 2 and 4, in some embodiments, the encryption method further includes:
step 015: under the condition that a request for opening the encrypted data is received, reading the key information stored in the encryption lock 100 and the key information of the encrypted data, and comparing the key information stored in the encryption lock 100 with the key information of the encrypted data;
step 016: in the case where the key information stored in the encryption lock 100 is identical to the key information of the encrypted data, the encrypted data is unlocked to acquire the original data.
Specifically, after the original data is encrypted, only the encryption lock 100 storing the same key information can complete the unlocking of the encrypted data and acquire the original data. Therefore, in the case of receiving a request for opening the encrypted data, the key information stored in the encryption lock 100 and the key information of the encrypted data are read, respectively, and the key information stored in the encryption lock 100 is compared with the key information of the encrypted data, so as to determine whether the encryption lock 100 has obtained the authorization of the target software. In the case where the key information stored in the encryption lock 100 is identical to the key information of the encrypted data, the encrypted data is unlocked to acquire the original data. In this way, by comparing the key information stored in the encryption lock 100 with the key information of the encrypted data, it is ensured that only the authorized encryption lock 100 can unlock the encrypted data and obtain the original data, so that effective management and control of the original data are facilitated, the security of the original data is improved, and even if other encryption locks 100 obtain the authorization of the target software where the original data is located, the original data cannot be obtained as long as the key information corresponding to the original data is not stored in the encryption lock 100.
For example, the target software has original data a and original data B in it, and both original data have been encrypted, resulting in encrypted data a and encrypted data B, respectively. The encryption lock a stores the key information corresponding to the encrypted data a, the encryption lock B stores the key information corresponding to the encrypted data B, and both the encryption locks 100 can obtain the authorization of the target software. Then, when decryption is performed, the encryption lock a will acquire authorization of the target software, and then complete unlocking of the encrypted data a, so as to obtain the original data a, however, since the encryption lock a has no key information corresponding to the encrypted data B, when the encryption lock a is used, the encrypted data B will not unlock the unauthorized encryption lock 100, and will always present an encrypted state, so that the risk of theft of the original data B is reduced. Similarly, when the encryption lock B is used, authorization of target software is firstly obtained, and unlocking of the encrypted data B is completed, so that the original data B can be obtained, the encrypted data A always presents an encryption state, and the original data A cannot be obtained under the condition that the used encryption lock is not the encryption lock A.
And when the key information stored in the encryption lock 100 is inconsistent with the key information of the encrypted data, the encryption method further includes:
step 017: in the case where the key information stored in the encryption lock 100 is inconsistent with the key information of the encrypted data, unlocking of the encrypted data is prohibited and a hint message is issued.
That is, when the key information stored in the encryption lock 100 is inconsistent with the key information of the encrypted data, it can be confirmed that the encryption lock 100 does not obtain the authorization of the encrypted data, unlocking the encrypted data is forbidden and prompt information is sent, at this time, the original data is still in an encrypted state, and related personnel still cannot use the original data, so that management and control of the original data are ensured, the risk of illegal acquisition of the original data is reduced, and the security of the original data is improved.
Referring to fig. 2 and 5, in some embodiments, the encryption method further includes:
step 018: encrypting the key information in the encrypted data again based on a preset encryption algorithm to generate secondary encrypted data;
step 019: reading key information stored in the encryption lock 100 and decrypting the secondary encrypted data to obtain encrypted data when a request for opening the encrypted data is received;
step 020: comparing the key information stored in the encryption lock 100 with the key information of the encrypted data;
step 021: in the case where the key information stored in the encryption lock 100 is identical to the key information of the encrypted data, the encrypted data is unlocked to acquire the original data.
Specifically, if the key information is directly written into the encrypted data without any processing, there is a risk that the key information may be leaked. Therefore, in order to secure the key information, the key information in the encrypted data is further secondarily encrypted, that is, the key information in the encrypted data is secondarily encrypted based on a preset encryption Algorithm, for example, an MD5Message-Digest Algorithm (MD 5) to generate secondarily encrypted data. When a request for opening the encrypted data is received, the key information stored in the encryption lock 100 may be read, and the secondary encrypted data may be decrypted based on a preset decryption algorithm, so that the encrypted data may be obtained. And then comparing the key information stored in the encryption lock 100 with the key information of the encrypted data, and unlocking the encrypted data when the key information stored in the encryption lock 100 is consistent with the key information of the encrypted data, thereby obtaining the original data. Therefore, the key information in the encrypted data can be exposed only when the key information is unlocked through secondary encryption of the key information, so that the risk that the key information of the encrypted data is easily leaked out is reduced, and the safety and controllability of the original data are improved.
For example, the MD5 information digest algorithm may be used as the preset encryption algorithm and the preset decryption algorithm. After the encrypted data is generated, the key information in the encrypted data is processed using the MD5message digest algorithm to generate the secondary encrypted data. After the original data is required to be acquired, the decryption of the secondary encrypted data is finished by using an MD5 information summary algorithm, so that the encrypted data is acquired. The key information stored in the encryption lock 100 and the key information of the encrypted data are then read and compared. When the two are consistent, the representative encryption lock 100 has obtained authorization of the original data, and the encrypted data can be unlocked at this time to obtain the original data.
Step 017 is also executed when the key information stored in the encryption lock 100 is inconsistent with the key information of the encrypted data, that is, when the key information stored in the encryption lock 100 is inconsistent with the key information of the encrypted data, unlocking the encrypted data is prohibited and a prompt message is issued. At this time, the software can learn that the encryption lock does not obtain authorization of the original data, and the original data is still in an encrypted state. Therefore, the security of the original data can be ensured, and the risk of stealing the original data in the software is reduced.

The encryption device 10 further comprises a writing module 13 and an authorization module 14. The writing module 13 writes information of the target software and key information into the storage space of the encryption lock 100; the authorization module 14 authorizes the read-write authority of the target software to the encryption lock 100 in the case where the information of the target software in the storage space matches the target software.

When the original data needs to be acquired, the encryption lock 100 is inserted into the machine station to complete the decryption of the encrypted data and the authorization of the acquisition target software. Therefore, after receiving the insertion operation of the encryption lock 100, the target software in the machine station will first go back to the information of the software in the encryption lock 100, so as to determine whether to authorize the encryption lock 100. When the information of the target software in the storage space matches the target software, the read-write authority of the target software to the encryption lock 100 is authorized. And then obtaining the key information stored in the encryption lock 100, comparing the key information with the key information in the encrypted data in the software, and if the key information stored in the encryption lock 100 is consistent with the key information of a certain encrypted data, obtaining the authorization of the encrypted data by the representative encryption lock 100, and at the moment, unlocking the encrypted data and obtaining the original data.
