Patent attributes
The technology disclosed herein provides network bound encryption that enables a trusted execution environment to persistently store and access recovery data without persistently storing the decryption key. An example method may include: transmitting combined key data that is based on a cryptographic key data of a second computing device to a third computing device; deriving a cryptographic key from combined key data received from the third computing device, the received combined key data being based on the cryptographic key data of the second computing device and cryptographic key data of the third computing device; and causing the trusted execution environment to use the cryptographic key to access sensitive data on a persistent storage device.
