Using a trusted execution environment for a cryptographic key wrapping scheme that verifies remote device capabilities

A system comprising:

• a memory;
• and
• a processing device communicably coupled to the memory, the processing device to:
• access a wrapped key that encodes a cryptographic key;
• execute instructions using a trusted execution environment to derive the cryptographic key in view of the wrapped key, wherein the executing to derive the cryptographic key comprises a task that consumes computing resources for a duration of time;
• use the cryptographic key to access program data;
• execute the program data, wherein the executed program data evaluates a condition related to the duration of time;
• and
• transmit a message comprising an indication of the evaluated condition, wherein the message indicates that the cryptographic key has been derived in view of the wrapped key within a predetermined minimum threshold time.

A non-transitory machine-readable storage medium storing instructions which, when executed, cause a processing device to perform operations comprising:

• receiving a wrapped key that encodes a cryptographic key;
• storing the wrapped key in an encrypted memory region of a trusted execution environment;
• executing, by a processing device using the trusted execution environment, instructions to derive the cryptographic key in view of the wrapped key, wherein the executing the instructions to derive the cryptographic key comprises a task that consumes computing resources for a duration of time;
• using the cryptographic key to access program data;
• executing, by the processing device, the program data, wherein the executed program data evaluates a condition related to the duration of time;
• and
• transmitting a message comprising an indication of the evaluated condition, wherein the message indicates that the cryptographic key has been derived in view of the wrapped key within a predetermined minimum threshold time.
