By default, BigQuery uses envelope encryption with Google-managed cryptographic keys to encrypt the data at rest. The data is encrypted using data encryption keys, and the data encryption keys themselves are further encrypted using key encryption keys. This is seamless and does not require any additional input from the user. For greater control, customer-managed encryption keys (CMEKs) can be used as an encryption key management solution for BigQuery datasets.
