Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The true meaning of the data security is that the usability and usability of the service system are ensured to the greatest extent on the premise of meeting the security of protecting core important data by users.
Protecting the security of data requires providing a secure and stable system environment, and should be a data-centric security system. The data-centric security architecture consists of two parts, data + environment. First, a trusted data environment, such as trusted people, devices, networks, applications, storage, etc., needs to be built. Secondly, techniques such as data controllability, identity authentication, content identification, encryption and the like are required.
From the viewpoint of data security, converting human-readable data into human-unreadable data, i.e., hiding human-understandable general meaning information, but only retaining machine-understandable associated information, is an effective method for protecting data security. Practical experience also teaches that most of the system processing information operates to screen and correlate, only when a person is engaged in a lane, is information that is understandable to humans required to be presented.
Based on the basic principle, the embodiment of the application provides a data security storage protection method for converting data expression forms through encryption technology. By hiding human comprehensible information, disclosure of personal privacy information and trade secrets due to theft of data is prevented. Meanwhile, a method of encrypting part of information instead of encrypting all the information is adopted, reasonable selection is made in the aspects of data security and availability, the relationship between the two is balanced, and both the data security and the service availability are considered.
The following describes the technical scheme provided by the embodiment of the application in detail through the attached drawings.
Fig. 1 is a flowchart of a data storage method according to an embodiment of the present application. As shown in fig. 1, the data storage method in the embodiment of the present application at least includes the following execution steps:
Step 101, generating a configuration file, and reading preset configuration parameters in the configuration file according to the service data.
Before data encryption and storage are performed, the data storage method provided by the embodiment of the application needs to determine the service data to be operated, and the service data can be designated by a user. Configuration of the configuration file, i.e. generating the configuration file, is then required.
Specifically, the preset configuration parameters included in the configuration file are determined first, that is, the parameters to be configured are determined first, and in one example of the present application, the preset configuration parameters at least include: the cryptographic algorithm type, the cryptographic algorithm name, the key type, the hash algorithm name, and the fixed parameter. The type of the cryptographic algorithm comprises a symmetric cryptographic algorithm and an asymmetric cryptographic algorithm. The symmetric cryptographic algorithm includes: SM1, AES DES, 3DES, RC2, RC4, RC5 and IDEA. The asymmetric cryptographic algorithm includes: SM2, RSA, DSA and ECC. The key types include public keys and symmetric keys. The hash algorithm includes: SM3, SHA-1 and MD5.
It should be noted that the whole service system may be configured with one cryptographic algorithm, or may set a plurality of different cryptographic algorithms according to a specific service, so as to adapt to a plurality of different security scenarios. Also, the entire service system may be configured with only a single key, or may be configured with multiple different keys according to a specific service, so as to adapt to multiple different security scenarios. Moreover, the whole service system can be configured with one hash algorithm, or a plurality of different hash algorithms can be set according to specific services so as to adapt to a plurality of different security scenes. Also, the whole service system can be configured with only one fixed parameter (salt), and a plurality of different fixed parameters (salts) can be set according to specific services so as to adapt to a plurality of different security scenes.
In one or more possible implementation manners of the embodiment of the present application, in order to ensure security of data such as a key in a configuration file, the configuration file may also be encrypted.
Further, after the configuration file is generated, the configuration parameters required when the service data is encrypted can be read in the configuration file according to the service data, namely, the cipher algorithm type, the cipher algorithm name, the key type, the hash algorithm name and the like corresponding to the service data encryption are read. In this process, if the type of cryptographic algorithm read is an asymmetric cryptographic algorithm, the type of key read is a public key. If the type of cryptographic algorithm read is a symmetric cryptographic algorithm, the type of key read is a symmetric key.
Step 102, determining data to be encrypted in the service data.
After the configuration parameters required by the encryption of the service data are determined, the service data can be encrypted, but in the embodiment of the application, in order to ensure the usability of the service data, only part of the data in the service data can be encrypted, namely only the data to be encrypted is encrypted, and the determination of the data to be encrypted can be specified by a user.
And step 103, carrying out encryption processing and hash calculation processing on the data to be encrypted according to the preset configuration parameters to obtain corresponding ciphertext data and hash values.
In this step, the plaintext designated by the user, that is, the data to be encrypted, may be encrypted by using the above-described read cryptographic algorithm (name) and key (type) to obtain corresponding ciphertext data. For example, the identification card number is encrypted to obtain the ciphertext of the identification card number.
Meanwhile, when the configuration parameters in the configuration file are read, a hash algorithm (name) and fixed parameters are also read, and at the moment, hash calculation can be carried out on a plaintext appointed by a user according to the hash algorithm and the fixed parameters to obtain a corresponding hash value. For example, hash calculation is performed on the identification card number to obtain the hash value of the identification card number
Thus, ciphertext data and a hash value corresponding to the data to be encrypted are obtained.
Step 104, storing the ciphertext data and the hash value into a preset data item.
In one example of the present application, the preset data item may be an entry in a data table corresponding to the data to be encrypted, that is, the encrypted ciphertext data is utilized to replace plaintext data at the position of the original entry in the data table.
The specific implementation process can be seen in fig. 2 and 3. Fig. 2 is a flowchart of encrypting and storing plaintext data in an application scenario according to an embodiment of the present application. As shown in fig. 2, the plaintext 1 is encrypted by a symmetric encryption algorithm or an asymmetric encryption algorithm to obtain a corresponding ciphertext 1, and then the ciphertext 1 is stored in a data table corresponding to the ciphertext 1. Fig. 3 is a flowchart of calculating and storing hash values of plaintext data in an application scenario according to an embodiment of the present application. As shown in fig. 3, the plaintext 1 obtains a corresponding hash value 1 through a hash algorithm, and then the hash value 1 is stored in a hash value 1 position in the data table.
In one or more possible implementation manners of the embodiment of the application, after ciphertext data is stored, if plaintext data corresponding to the ciphertext data is required to be checked, at this time, the ciphertext data is required to be searched according to a plaintext search term input by a user, and then the searched ciphertext data is decrypted to obtain the corresponding plaintext data.
Specifically, fig. 4 is a flowchart of ciphertext data retrieval under an application scenario provided by an embodiment of the present application. Before searching, firstly, the name and fixed parameters (salt) of the hash algorithm are required to be read from the configuration file according to the service data. Then, as shown in fig. 4, the plaintext search term is determined according to the search request, and then the hash algorithm and the fixed parameter (salt) can be utilized to perform hash calculation on the plaintext search term designated by the user to obtain a corresponding search term hash value. And finally, inquiring ciphertext data from the data table by using the retrieval word hash value as a retrieval condition, namely, matching or comparing the retrieval word hash value with the hash value in the data table, and feeding back the inquiry result data to the user so as to enable the user to acquire the ciphertext data corresponding to the plaintext retrieval word.
Further, when decrypting the ciphertext data, the type of the cryptographic algorithm, the name of the cryptographic algorithm and the secret key need to be read from the configuration file according to the service data. At this time, if the type of the read cryptographic algorithm is an asymmetric cryptographic algorithm, the read key is a private key. If the type of cryptographic algorithm read is a symmetric cryptographic algorithm, the key read is a symmetric key. And then, decrypting the ciphertext data in the search result by using the cryptographic algorithm and the key to obtain corresponding plaintext data. At this time, if the type of the cryptographic algorithm is an asymmetric cryptographic algorithm, decryption is performed by using the asymmetric cryptographic algorithm and the private key. And if the type of the cryptographic algorithm is a symmetric cryptographic algorithm, decrypting by using the symmetric cryptographic algorithm and the symmetric key. For example, the ciphertext of the identification card number is decrypted to obtain a plaintext identification card number. Finally, the decrypted plaintext data is fed back to the user, and the implementation of the process is shown in fig. 5.
In one or more possible implementation manners of the embodiment of the present application, in order to improve the searching efficiency in the searching process, the data table may be associated with the plaintext data required for feedback to the user as soon as possible. Specifically, two data tables are associated by taking a hash value as a key value, so that associated combined data is obtained, and then the hash value retrieval is carried out on the combined data. Fig. 6 is a flowchart of data table association under an application scenario provided by the embodiment of the present application, as shown in fig. 6, two data tables containing the same ciphertext 1 and hash value 1 are combined, and when the two data tables are combined, the positions of the ciphertext 1 and hash value 1 are unchanged, and the following plaintext data are combined, so that when the hash value is used for searching, two tables containing hash value 1 do not need to be searched, but only the related data tables need to be searched and queried.
The data storage method provided by the embodiment of the application has the following beneficial effects:
1) The hash value of the plaintext data is calculated by utilizing the hash algorithm, the symmetric ciphertext of the plaintext data is calculated by utilizing the password algorithm, and only the hash value and the ciphertext are stored in the database, so that the plaintext data is not stored, the problem of safe storage of the data is solved, and the data leakage caused by the attack of the system is prevented.
2) Because the hash value of the plaintext data is stored, the data can still be retrieved and queried under the state of secret storage.
3) Because the hash value has the characteristic of fixed length, the optimization problem of the data query performance can be completed by combining the characteristic with database means such as indexes.
4) By utilizing the characteristic of fixed length of the hash value, the association inquiry among the data tables can be realized, and the data inquiry speed is improved.
5) The ciphertext is stored, and the ciphertext can be decrypted by using a decryption algorithm for viewing by a user when necessary.
In a word, the method in the embodiment of the application not only solves the problem of data secret storage, but also solves the problems of quick data inquiry, quick association inquiry and data use, thereby realizing the safety and usability of the data.
