Abstract:
A system for generating symmetric cryptographic keys for communications between hosts. Hosts use associated devices to generate secret keys. Each key is generated based on a static seed and a dynamic seed. The dynamic seed is created from sensor data or auxiliary data. The secret key allows host machines to encrypt, or decrypt, plaintext messages sent to, or received from, other host machines.

Claim (Index 10):
The system of  claim 7 , wherein the second device is further configured to\n receive an encrypted identifier message encrypted by the system of  claim 5 , decrypt the encrypted identifier message using the static seed used by the first host machine to obtain the auxiliary data, if present, identify a plurality of dynamic seeds using a plurality of values for sensor data combined with the auxiliary data, if present, and identify a correct dynamic seed from the plurality of dynamic seeds that, when input with the static seed to a key generation function, produces a key that generates a message authentication code that matches the message authentication code included in the encrypted identifier message.
