System and method for shared key agreement over untrusted communication channels

A method for generating cryptographic keys comprising:

• generating with a first processor in a first computing device, error correction data corresponding to first sensor data that is stored in a first memory in the first device;
• generating with the first processor in the first computing device a first cryptographic key with reference to a first hashed value corresponding to the first sensor data;
• generating with the first processor in the first computing device a first message authentication code (MAC) with reference to the first cryptographic key and the error correction data;
• and
• transmitting with a first input/output (I/O) device in the first computing device the error correction data and the first MAC through a communication channel to a second computing device to enable the second computing device to generate a second cryptographic key in the second computing device with reference to second sensor data.
