New Providers for ScyllaDB Enterprise Encryption at Rest

We introduced encryption at rest with ScyllaDB 2019.1.1. ScyllaDB Enterprise protects your sensitive data with data-at-rest encryption.

One of the key elements of encryption at rest is storing the encryption keys, and for obvious reasons: if lost, your data become unreadable; if compromised, your data might be exposed.

The encryption key storage options are determined in ScyllaDB by selecting a Key Provider.

ScyllaDB 2019.1.1 only supported with one Key Provider: Local, which allows you to keep keys the file system for each node.

ScyllaDB 2019.1.3 adds two more Key Providers:

  • Table provider, allows you to store table keys in ScyllaDB Tables and eliminates the need to copy the table key to each server.
  • KMIP provider. KMIP is a standard protocol for exchanging keys in a secure way. With this key provider, you can use any KMIP compatible server to secure ScyllaDB Encryption keys.
