Understanding the Basics of Data Encryption
What is Data Encryption?
Data encryption is the process of converting data into a code or cipher so that only authorized parties can access it. This process uses algorithms to transform readable data (plaintext) into an unreadable format (ciphertext).
- Data encryption ensures the confidentiality and integrity of sensitive information.
- It provides an additional layer of security beyond traditional firewalls.
- Only those with the right encryption key can decipher the unreadable data to access the original information.
Implementing data encryption is crucial for small businesses to protect their valuable data and prevent unauthorized access or interception during transmission.
How Does Data Encryption Work?
Data encryption involves selecting an encryption algorithm and a key. When data is encrypted, the algorithm transforms it using the key. The resulting ciphertext can only be turned back into readable plaintext with the correct key. There are mainly two types of encryption: Symmetric encryption, where the same key is used for both encryption and decryption, and Asymmetric encryption, which uses two different keys – a public key for encryption and a private key for decryption.
Here are two methods your provider may use to encrypt data as it is being stored:
-
Full-disk: Full-disk encryption might use the Advanced Encryption Standard (AES), which encrypts fixed data stores. Keys using AES have options for texts that can be 128, 192, or 256 bits. The key or passphrase is entered directly when the system boots up.
-
Database: This type of encryption is done on servers and may also use AES for encryption. Since these data centers are remote in most cases, remote passphrase or key entry is used by administrators when the databases start up.
Types of Data Encryption Algorithms
There are several types of data encryption algorithms that are commonly used to secure sensitive information. One such algorithm is the Advanced Encryption Standard (AES), which is widely regarded as one of the most secure encryption methods available. AES allows for different key sizes, including 128, 192, and 256 bits, providing flexibility in choosing the level of security required.
Another commonly used encryption method is the RSA algorithm, which is an asymmetric encryption algorithm. It uses two different keys – a public key for encryption and a private key for decryption. This allows for secure communication between parties without the need to share a secret key.
In addition to AES and RSA, there are other encryption algorithms such as Triple DES, Blowfish, and Twofish that offer different levels of security and performance. It is important for small businesses to carefully evaluate and choose the appropriate encryption algorithm based on their specific needs and requirements.
