1. A data security apparatus, comprising:
an analog component, configured to provide a sensor output;
control circuitry comprising a circuit configured to perform predefined operations;
the predefined operations comprising:
obtaining a plaintext message M;
generating an analog component input for the analog component, the analog component input being based on a nonce N;
sending the analog component input to the analog component as drive signals to drive the analog component to provide the sensor output;
digitally representing the sensor output to obtain an analog component output Ao;
generating a digital keystream S based on the analog component output Ao;
generating a ciphertext C based on the digital keystream S and on the plaintext message M; and
outputting the ciphertext C and the nonce N.
