Data encryption, which prevents data visibility in the event of its unauthorized access or theft, is commonly used to protect data in motion and increasingly promoted for protecting data at rest. [9] The encryption of data at rest should only include strong encryption methods such as AES or RSA. Encrypted data should remain encrypted when ...
Transparent data encryption (often abbreviated as TDE) is used to encrypt an entire database, [2] which therefore involves encrypting "data at rest". [4] Data at rest can generally be defined as "inactive" data that is not currently being edited or pushed across a network. [5] As an example, a text file stored on a computer is "at rest" until ...
Transparent Data Encryption (often abbreviated to TDE) is a technology employed by Microsoft, IBM and Oracle to encrypt database files. TDE offers encryption at file level. TDE enables the encryption of data at rest, encrypting databases both on the hard drive and consequently on backup media. It does not protect data in transit nor data in use.
Homomorphic encryption and secure multi-party computation are emerging techniques to compute encrypted data; these techniques are general and Turing complete but incur high computational and/or communication costs. In response to encryption of data at rest, cyber-adversaries have developed new types of attacks.
Compromising data in use enables access to encrypted data at rest and data in motion. For example, someone with access to random access memory can parse that memory to locate the encryption key for data at rest. Once they have obtained that encryption key, they can decrypt encrypted data at rest.
Confidential computing can be used in conjunction with storage and network encryption, which protect data at rest and data in transit respectively. [ 1 ] [ 2 ] It is designed to address software, protocol, cryptographic, and basic physical and supply-chain attacks, although some critics have demonstrated architectural and side-channel attacks ...

Disk encryption is a special case of data at rest protection when the storage medium is a sector-addressable device (e.g., a hard disk). This article presents cryptographic aspects of the problem. This article presents cryptographic aspects of the problem.
