Data at rest encryption terminology
The following table describes the data at rest encryption terminology.
Table: Data at rest encryption terminology
Term | Description |
|---|---|
Advanced Encryption Standard (AES) |
Specifies the synchronous encryption algorithm that replaced DES. |
Asynchronous encryption |
Includes the encryption algorithms that use both a public key and private key. |
Data Encryption Standard (DES) |
Specifies the accepted synchronous data encryption standard from the 1970s until 1998. |
Initialization vector |
Specifies a seed value that is used to prime an encryption algorithm. Priming is done to obscure any patterns that would exist when using the same key to encrypt a number of data files. These files begin with the same pattern. |
Public Key Encryption |
Uses asynchronous encryption. |
Synchronous encryption |
Includes the encryption algorithms that use the same key for both encryption and decryption. For the same key size, synchronous algorithms are faster and more secure than their asynchronous counterparts. |
