The cloud platform further comprises a cloud end which is in communication connection with the client, can carry various services, can respond to the request and provide the services when receiving the request of the client, and sends the returned data to the client.
The cloud end usually can dock many clients, and data processing and resource pressure of the cloud end equipment are great. Thus, the cloud may be connected to a remote device of a third party, e.g., a database, a server, a request for data services or data storage for the cloud.
In the related art, due to poor security of the cloud or the remote device connected to the cloud, when the cloud stores the backup data on the remote device, there is a risk of easy tampering. The embodiment provides a remote data backup method of a cloud platform, which generates a hash value by utilizing a hash function through backup data of a database to be backed up, encrypts the hash value by utilizing a random key, and generates encrypted data for storage. The security of the backup data is improved.
The data backup request is sent by the client, and because the client data of the cloud platform are stored in the database of the cloud, the cloud responds to the data backup request after the client sends the data backup request to the cloud, and the backup data corresponding to the data backup request is obtained. Thus, the data backup request also includes identification information indicating the backup data.
And after receiving the data backup request, the cloud terminal responds to the data backup request, calls a key generation service and randomly generates a random key. After the backup data is obtained, a hash function is used for processing to generate a hash value. The generated hash value is then encrypted with a random key.
The HASH function may be a HASH function. The random key may be a DES key.
Optionally, generating the random key in response to the data backup request includes: bit key data of numbers and letters is randomly generated as a random key in response to a data backup request; and storing the random key and the request information of the data backup request.

The security of the database is higher, the acquisition difficulty of the random key can be improved, and the security is further improved.
Optionally, obtaining backup data of the database, storing locally includes: sending a backup message to a database; obtaining backup data generated by a database in response to the backup message; and storing the acquired backup data in a cloud local.
When the cloud terminal obtains the backup data corresponding to the data backup request, the cloud terminal can find out the database where the backup data is located according to the identification information carried in the data backup request, and send a backup instruction to the database so as to enable the database to generate backup data required by backup. The backup data is then stored locally at the cloud for subsequent generation of the hash value.
Optionally, after storing the backup data in the target location of the cloud and storing the encrypted data in the target directory of the cloud, the method further includes: and deleting the backup data stored locally in the cloud.
After the backup data is hashed and encrypted by a random key to generate encrypted data, the local backup data is deleted to ensure the safety of the backup data.
The encrypted data is stored in the target directory of the cloud end, so that the encrypted data can be quickly and directly obtained from the target directory when the data backup is carried out later. The backup data can be checked more quickly, and the efficiency of checking the backup data is improved.
Optionally, before storing the backup data in the target location of the cloud and storing the encrypted data in the target directory of the cloud, the method further includes: searching whether a target directory exists in the cloud; and in the case that the target directory does not exist, creating the target directory or selecting the target directory from the existing file directories in the cloud.
Before storing the encrypted data in the target directory, it may be detected whether the target directory exists, and if the target directory exists, the encrypted data is stored, and if the target directory does not exist, the target directory is automatically created, and then the encrypted data is stored in the target directory.

step S201, receiving a backup recovery request sent by a client of a cloud platform, wherein the backup recovery request is used for indicating a database of a cloud end of the cloud platform to perform backup recovery;
step S202, responding to a backup recovery request, obtaining a corresponding random key and backup data, and obtaining encrypted data of the backup data of a database from a target directory, wherein the backup data has a cloud target position, and the encrypted data is encrypted by the random key and is stored in the target directory;
step S203, decrypting the encrypted data through the random key to obtain a decrypted hash value;
step S204, generating a hash value from the backup data through a hash function;
in step S205, when the hash value of the backup data matches the decrypted hash value, backup recovery is performed by the backup data.
The steps are used for responding to the backup recovery request, obtaining a corresponding random key, backing up data and encrypting data, decrypting the encrypting data through the random key to generate a hash value, generating the hash value from the backing up data through a hash function, and determining whether the backing up data is tampered or not through comparison of the hash value of the backing up data and the decrypted hash value. The method and the device have the advantages that the backup is carried out by double encryption of the backup data of the cloud database of the cloud platform, the safety of the backup data is guaranteed, the safety degree of the backup data is improved, the risk of falsification of the backup data is reduced, and the backup data can be accurately detected after falsification.

Optionally, in a case where the hash value of the backup data is consistent with the decrypted hash value, performing backup recovery by the backup data includes: comparing the hash value of the backup data with the hash value obtained by decryption; executing the step of backup recovery through the backup data under the condition that the hash value of the backup data is consistent with the hash value obtained by decryption; and sending risk information to the client when the hash value of the backup data is inconsistent with the hash value obtained by decryption.
Whether the encrypted data is modified or not can be detected by comparing the hash value of the backup data with the hash value obtained by decryption, so that the safety of the backup data is further improved. It should be noted that the encrypted data may be stored in other trusted databases to avoid the possibility of the encrypted data being modified together.
Thus, the original hash value may be obtained from the trusted database prior to comparing the decrypted backup data with the original hash value. And then comparing the decrypted backup data with the original hash value.
Optionally, in the case that the hash value of the backup data is inconsistent with the hash value obtained by decryption, after the risk information is sent to the client, the method further includes: and responding to the operation of continuing to restore, which is executed on the client, and executing the step of restoring the backup through the backup data.
After the risk information is sent to the client, if the client still chooses to resume, the client should give priority to the client's will, and continue to execute the step of performing backup resume through the backup data.
It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is illustrated in the flowcharts, in some cases the steps illustrated or described may be performed in a different order than that illustrated herein.
It should be noted that this application also provides an alternative embodiment, and the following detailed description of this embodiment is provided.
The embodiment provides a trusted method and a trusted device for remotely backing up and recovering cloud platform data. The following describes terms related to the present embodiment:
hashing function: an arbitrary length input is transformed by a hashing algorithm into a fixed length output, which is the hash value. This transformation is a compressed mapping, i.e. the hash value is usually much smaller in space than the input, simply a function of compressing messages of arbitrary length to a message digest of a certain fixed length.
Symmetric encryption: the same key can be used for both encryption and decryption of information using an encryption method of a single key cryptosystem, which is called symmetric encryption, also called single key encryption.
DES (Data Encryption Standard): the DES algorithm is a symmetric cryptosystem in the cryptosystem, also known as the american data encryption standard. The plaintext is grouped according to 64 bits, the key is 64 bits long, the key is actually 56 bits to participate in the DES operation (8 th, 16 th, 24 th, 32 th, 40 th, 48 th, 56 th and 64 th bits are check bits, so that each key has an odd number of 1), and the grouped plaintext group and the 56-bit key form an encryption method of the ciphertext group by a bit substitution or exchange method.
UUID (Universally Unique Identifier) UUID is an abbreviation for universal unique identification code, a standard for software construction, and is also part of the open software foundation organization in the field of distributed computing environments. The purpose is to make all elements in the distributed system have unique identification information without the need of specifying the identification information by a central control terminal.
Fig. 3 is a schematic diagram of a data backup flow provided according to an embodiment of the present application, and as shown in fig. 3, a specific flow of data backup is as follows:
and S1, initiating a data backup request of the cloud platform by the front end, randomly generating 64-bit key data containing numbers and letters by the platform disaster recovery service after receiving the request, and recording the key data, the initiation time of the request and other contents in a database of the platform disaster recovery service.
And S2, the disaster recovery service is connected with the cloud platform database to prepare for backup of the database.
S3, the disaster recovery service needs to backup the database of the current cloud platform to a/home/backup catalog of the current server (if the catalog does not exist, the creation is needed). The name of the backup data is the current year, month, day, time, second plus the randomly generated UUID.
S4, the disaster recovery service needs to generate a hash value with a fixed length from the backup data through a hash function.
S5, the disaster recovery service symmetrically encrypts the hash value generated in S4 by using the key generated in S1.
And S6, uploading the data backup data to a/home/backup catalog of the remote server by the disaster backup service (if the catalog does not exist, the creation is needed) and deleting the local data backup data.
Fig. 4 is a schematic diagram of a data recovery flow provided according to an embodiment of the present application, and as shown in fig. 4, a specific flow of data recovery is as follows:
and S7, initiating a data recovery request of the cloud platform by the front end, and after receiving the request, the disaster recovery service needs to inquire a symmetric encryption key corresponding to the backup record and decrypt a hash value generated when the backup is carried out through the key.
And S8, if the hash value is successfully decrypted, the remote server needs to be accessed to acquire the database backup data.
And S9, accessing a remote server to acquire database backup data.
S10, generating a hash value with a fixed length from the database backup data through a hash function.
And S11, comparing whether the hash value of the database backup data to be restored is consistent with the decrypted hash value.
S12, the inconsistent hash values indicate that the current database backup data is modified, the possibility of containing malicious database commands exists in the file, the user needs to be prompted through the front end, and the user decides whether to continue to execute the recovery operation.
S13, the hash value is consistent to indicate that the current database backup data is not modified, and the recovery operation can be normally executed.
Here, for example, creating a data backup and performing a data recovery operation, first, a user a functioning as a system administrator is created in the cloud platform.
After the user A logs in the cloud platform, a data backup request is initiated, the address of a remote server is 10.10.10.10, and the account number and the password of the server are correctly filled in. After receiving the data backup request, the platform disaster recovery service randomly generates a DES encryption key of the current data backup request task and starts to generate backup data of the cloud platform database. After the backup data is generated, the backup data needs to be generated into a hash value with a fixed length through a hash function, encrypted by using a key generated randomly before and stored. After all of the above tasks are completed, the database backup data needs to be uploaded to a remote server.
After the user A logs in the cloud platform, a designated data backup record is required to be selected to initiate a data recovery request, a previously encrypted hash value is firstly required to be decrypted according to a key of the record, then a remote server which needs to access the backup obtains database backup data, the hash value of the current database backup data is obtained through a hash function, and whether the previously decrypted hash value is consistent with the hash value of the current database backup data or not is compared. If the data are consistent, the database backup data are not modified, and a recovery operation can be executed; if the hash values are inconsistent, the database backup data is tampered, a certain security risk is provided, the front end needs to be prompted, and a user decides whether to continue to execute the recovery operation.
The key point of this embodiment is that when executing data backup, a hash function is used to generate a hash value of a database file and encrypt and store the hash value, before executing data recovery, the decrypted hash value is compared with the hash value of the database file stored by the current remote server to determine whether the database file to be executed is modified, if the hash values are inconsistent, the user is reminded to determine whether to execute data recovery, so as to avoid executing malicious database scripts and affecting the cloud platform.
