HBase Data Encryption (Configuration for Transmission and Storage Encryption)

Data encryption refers to converting non-sensitive data into a secure form to ensure it cannot be accessed by unauthorized parties during transmission or storage. Data encryption is typically implemented using encryption algorithms and symmetric keys or public-private key pairs.

Transport Encryption

Transport encryption refers to adding a layer of protection to data so that it can be transmitted securely over a network. This type of encryption typically uses symmetric keys, which are used by both the sender and the receiver to encrypt and decrypt data.

Symmetric Key Algorithms

1. AES (Advanced Encryption Standard): AES is a commonly used symmetric key algorithm that provides strong security.

2. DES (Data Encryption Standard): DES is an older symmetric key algorithm that has been replaced by AES.

Symmetric Key Management

1. key exchange: key exchange is a method used to exchange symmetric keys, ensuring secure key delivery.

2. symmetric key distribution: symmetric key distribution refers to using the same method to distribute symmetric keys, ensuring the security of the keys.

Storage Encryption

Storage encryption refers to adding a layer of protection to data so that it can be stored securely on hard drives or other storage devices. This type of encryption typically uses public-private key pairs.

Public-Private Key Pairs

1. RSA (Rivest-Shamir-Adleman): RSA is a commonly used public-private key pair algorithm that provides strong security.

2. ECDSA (Elliptic Curve Digital Signature Algorithm): ECDSA is an encryption algorithm used for digital signatures.

Storage Encryption Methods

1. AES-256: AES-256 is an encryption method using the AES algorithm and a 256-bit key.

2. RSA-OAEP: RSA-OAEP is an encryption method using the RSA algorithm and the OAEP (Optimal Asymmetric Encryption Padding) mode.

Symmetric Encryption Storage

1. AES-256: AES-256 is a symmetric encryption method using the AES algorithm and a 256-bit key.

2. PBKDF2: PBKDF2 is a symmetric encryption method used to generate keys from passwords.

Asymmetric Encryption Storage

1. RSA-2048: RSA-2048 is an asymmetric encryption method using the RSA algorithm and a 2048-bit public-private key.

2. ECDSA-SHA256: ECDSA-SHA256 is an asymmetric encryption method using the ECDSA algorithm and the SHA256 hash function.
