Three types of keys are used in encrypting and decrypting data: the Master Encryption Key (MEK), Data Encryption Key (DEK), and Block Encryption Key (BEK). The MEK is used to encrypt the DEK, which is stored on persistent media, and the BEK is derived from the DEK and the data block. If you are managing your own keys, you can rotate the MEK.

Data encryption is typically split into encryption in transit and encryption at rest. Encryption in transit is used to prevent people reading information sent between you and the Internet or network service you are using. A lot of data is transmitted these days, lots of private information is exchanged. In order to save the private data from any malicious attack encryption is used. This article covers, what is encryption, types of data encryption, why and when is encryption used, how encryption works, encrypting data “In Transit” vs. Data “At Rest” and benefits of encryption. In technical terms, it is the process of converting plaintext to ciphertext. In simpler terms, encryption takes readable data and alters it so that it appears random. Encryption requires the use of an encryption key: a set of mathematical values that both the sender and the recipient of an encrypted message know. Encryption enhances the security of a message or file by scrambling the content. To encrypt a message, you need the right key, and you need the right key to decrypt it as well.It is the most effective way to hide communication via encoded information where the sender and the recipient hold the key to decipher data.

As for data in-flight, the new encrypted network technologies and also more traditional network encryption like IPsec are finding new ways to secure data as it is transmitted across the wire. Securing data by encryption today requires you use multiple technologies to secure data both at-rest and in-flight.

iOS has been encrypting data for years, and encryption is now switched on by default in macOS as well: To check, open System Preferences, click Security & Privacy, then open the FileVault tab. If

Apr 07, 2018 · Data processing is in also gaining importance and the availability of types of data processing makes it easier to differentiate and segregate the data for later use. Encryption too can be considered as a part of data processing and a step of same.
