Abstract
Operations include: receiving a first request for a first dataset of a plurality of datasets stored in a particular database instance; obtaining an encrypted version of the first dataset; obtaining an encrypted version of the first DEK; requesting decryption of the encrypted version of the first DEK; receiving a decrypted version of the first DEK; applying the first DEK to the encrypted version of the first dataset to obtain a decrypted version of the first dataset; and transmitting the decrypted version of the first dataset. The first dataset is encrypted by a first DEK associated with a first tenant. A second dataset is encrypted by a second DEK associated with a second tenant. The decrypted version of the first DEK is generated by applying a first MEK of the first tenant to the encrypted version of the first DEK.
