Protecting key confidentiality is essential for many kernel security use-cases such as disk encryption, file encryption and protecting the integrity of file metadata. Trusted and encrypted keys provides a mechanism to export keys to user-space for storage as an encrypted blob and for the user-space to later reload them onto Linux keyring without the user-space knowing the encryption key. The existing Trusted Keys implementation relied on a TPM device but what if you are working on a system without one?

This session will introduce a Trusted Keys implementation which relies on a much simpler trusted application running in a Trusted Execution Environment (TEE) for sealing and unsealing of Trusted Keys using a hardware unique key provided by the TEE.
