Abstract: Techniques are disclosed relating to securely storing data in a computing system. In some embodiments, a computing system performs a boot sequence that includes generating ephemeral key data and preventing the generated ephemeral key data from being stored in a non-volatile storage including persisting the generated ephemeral key data in the volatile storage. The boot sequence further includes creating, in the non-volatile storage, an ephemeral data volume and encrypting the ephemeral data volume by using the ephemeral key data persisted in the volatile storage.
