Abstract
A method for generating keys in a multi-cloud environment that minimizes the impact of a breach may include: generating and storing a first key encryption key (KEK) in a first environment key management service (KMS); generating a first data encryption key (DEK) using the first KMS; generating a second DEK for a second environment using the first KMS; encrypting the first DEK with the first KEK and the second DEK with the first KEK; storing the encrypted first DEK and the encrypted second DEK in a database; generating a second KEK and storing the second KEK in a second environment KMS; encrypting the first DEK with the second KEK and the second DEK with the second KEK; and storing the encrypted first DEK and the encrypted second DEK in the database.
