What are the digital safe encryption technologies?

Digital safe encryption technology

Digital safe encryption technology aims to protect the security of data during storage and transmission and prevent the data from being stolen or tampered with. The following are some common digital safe encryption technologies:

Symmetric encryption

Symmetric encryption is a traditional encryption method. In this method, the same key is used for both encryption and decryption. Its main advantage is that the encryption and decryption speeds are fast, making it suitable for processing large amounts of data. However, its security depends on the confidentiality of the key. For example, symmetric encryption technology may be used in the encrypted storage of data in the private safes of some cloud services to ensure the security of data during transmission and storage.

Abstract (Hash Algorithm) Service

Digest (hash algorithm) service is a cryptographic technique used to convert data into a fixed-length string, commonly referred to as a hash value or digest. This service ensures the integrity of information by verifying whether the data has been tampered with during transmission or storage. Hash algorithms are widely used in fields such as password storage, data verification, and secure communication. For example, in a digital safe, the stored data can be verified through the hash algorithm to ensure that the data has not been maliciously modified.

End-to-end encryption technology

Take the Mixia APP as an example. It uses end-to-end encryption technology, and the private key is kept by the user themselves. This ensures that only the user can decrypt the data, and no one, not even the developer, can decrypt it. Meanwhile, this technology also allows the user to add users of the encrypted files and set the usage permissions and usage time for the users, further ensuring the security and privacy of the data.

Transparent Data Encryption (TDE)

In SQL Server database backup encryption, Transparent Data Encryption (TDE) is a commonly used encryption technology. It can protect backup files and prevent data from being stolen or tampered with during storage or transmission. When using TDE, the database automatically encrypts and decrypts data in the background, and users do not need to intervene manually, which improves the security of data backup.

Backup encryption options

In addition to TDE, SQL Server also provides backup encryption options to protect backup files. Backup encryption is protected using keys, and these keys need to be properly managed. To maintain the security of data backups, the encryption keys should be replaced regularly.
