Data encryption storage measures
Data encryption storage measures include database-level encryption, media-level encryption, embedded encryption devices, and application encryption. If you want to know more about data encryption, you can read the articles below this topic.
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.
Data encryption and decryption technology for PHP database connectionOverview of data encryption and decryption technology for PHP database connections: With the rapid development of the Internet, databases have become one of the main tools for storing and managing large amounts of data worldwide. However, with the increase of sensitive data in databases, data security becomes more and more important. In PHP applications, we often need to store sensitive data in the database, such as user passwords, credit card information, etc. To ensure the confidentiality of this sensitive data, we can use encryption and decryption technology to protect the security of the data. This article will introduce the PH
How to use PHP to implement a simple data encryption functionHow to use PHP to implement a simple data encryption function requires specific code examples. In the modern Internet era, data security has become an issue that we cannot ignore. In website development, to protect some sensitive data, we need to use encryption algorithms to prevent data leakage and tampering. PHP is a scripting language widely used in server-side development. It provides a wealth of encryption functions and algorithms. This article will introduce how to use PHP to implement a simple data encryption function and give specific code examples. 1. Using PHP
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 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.
