Abstract
Systems for exchanging encrypted data communications between devices. A system can comprise a first device and a second device. The first device can comprise a first sensor adapted to create a first data profile based at least in part on a sensed condition, and a first transceiver integrated with the first sensor and adapted to generate a first cryptographic key from the first data profile. The second device can comprise a second sensor adapted to create a second data profile based at least in part on the sensed condition, the second data profile being substantially similar to the first data profile, and a second transceiver integrated with the second sensor and adapted to generate a second cryptographic key from the second data profile, the first and second cryptographic keys comprising a set of identical cryptographic keys.
