What are the common encryption methods for data encryption storage? Common encryption methods for data encryption storage: 1. Symmetric encryption; 2. Asymmetric encryption; 3. Hash encryption. Detailed introduction: 1. Symmetric encryption refers to using the same key for encryption and decryption operations, that is, the same key is used for encryption and decryption; 2. Asymmetric encryption refers to using different keys for encryption and decryption operations. That is, the encryption key and the decryption key are different; 3. Hash encryption refers to converting data into a fixed-length hash value through a hash function, that is, an irreversible mapping from plaintext to ciphertext, etc.

What does data encryption storage include? Data encryption storage includes technologies and methods such as symmetric encryption, asymmetric encryption, hash functions, data encryption algorithms, key management, multi-factor authentication and secure storage devices. Detailed introduction: 1. Symmetric encryption, fast and simple encryption and decryption process; 2. Asymmetric encryption, providing higher security; 3. Hash function, which is irreversible, that is, the original data cannot be restored from the hash value. ; 4. Data encryption algorithm, which performs complex mathematical operations on data so that unauthorized users cannot decrypt the data; 5. Key management, etc.

What does data encryption storage include? Data encryption storage includes symmetric encryption, asymmetric encryption, hash algorithm, digital signature and other methods. Detailed introduction: 1. Symmetric encryption. During the encryption process, the original data and key are calculated by the encryption algorithm to generate encrypted ciphertext; 2. Asymmetric encryption. During the asymmetric encryption process, the data encrypted with the public key only Can be decrypted with the private key and vice versa; 3. Hash algorithm, which can verify the integrity and consistency of the data during data transmission and storage; 4. Digital signature, etc.

What are the data encryption storage measures? Data encryption storage measures include: 1. Database-level encryption: Encryption of data fields can be achieved; 2. Media-level encryption: Encryption of static data on storage devices can provide high transparency for users and applications, but only Data can be encrypted only after it reaches the storage device, so media-level encryption can prevent theft of physical storage media; 3. Embedded encryption device: It can encrypt the data of the storage device and protect static data, but the embedded encryption device expands It is difficult and costly; 4. Application encryption: Integrate encryption technology into commercial applications.
