1. A system comprising:
an electronic circuit including:
a first set of electronic circuit elements electrically coupled to:
receive first secret data that was encrypted externally to the electronic circuit according to a data key; and
decrypt the first secret data based in part on parameters included in the data key;
a second set of electronic circuit elements electrically coupled to generate second secret data by executing one or more operations on the first secret data;
a third set of electronic circuit elements electrically coupled to encrypt the second secret data based in part on the parameters included in the data key, thereby providing encrypted second secret data for output; and
a fourth set of electronic circuit elements electrically coupled to:
receive configuration data that was encrypted externally to the electronic circuit according to a public key; and
decrypt the configuration data based in part on parameters included in a private key that is associated with the public key, wherein the private key is included in the electronic circuit and not accessible, either directly via a connection or indirectly via side channels, to computing devices external to the electronic circuit.
