1. A system-on-a-chip (SoC), comprising:
a secure subsystem storing a cryptographic key and configured to:
receive an input from a sensing circuit relevant to a condition for performing a cryptographic function using the cryptographic key, wherein the condition is associated with performance metrics of the sensing circuit;
receive a request to perform the cryptographic function from a service requesting environment, wherein the received request is distinct from the received input from the sensing circuit; and
perform the cryptographic function in response to receipt of the request to perform the cryptographic function and the received input indicating that the condition for performing the cryptographic function is satisfied.
