Data encryption is a security method where information is encoded and can only be accessed or decrypted by a user with the correct encryption key. Encrypted data, also known as ciphertext, appears scrambled or unreadable to a person or entity accessing without permission. How Data Encryption is Used

But the most popular forms of security all rely on encryption, the process of encoding information in such a way that only the person (or computer) with the key can decode it. In this article, you will learn about encryption and authentication. You will also learn about public-key and symmetric-key systems, as well as hash algorithms. The encryption uses a database encryption key (DEK). The database boot record stores the key for availability during recovery. The DEK is a symmetric key. It's secured by a certificate that the server's master database stores or by an asymmetric key that an EKM module protects. May 06, 2019 · Device encryption helps protect your data, and it's available on a wide range of Windows devices. If you turn on device encryption, the data on your device can only be accessed by people who've been authorized. If device encryption isn't available on your device, you may be able to turn on standard BitLocker encryption instead. Jul 31, 2019 · Encryption helps protect the data on your device so it can only be accessed by people who have authorization. If device encryption isn't available on your device, you might be able to turn on standard BitLocker encryption instead.
