1. A system for exchanging encrypted data communications comprising:

  • a first device comprisinga first sensor adapted to create a first data profile based at least in part on a sensed condition, anda first transceiver integrated with the first sensor and adapted to generate a first cryptographic key from a first sequence of segments of the first data profile, each segment comprising at least one data point sensed by the first sensor; and

    a second device comprisinga second sensor adapted to create a second data profile based at least in part on the sensed condition, the second data profile being sufficiently similar to the first data profile to enable generation of a set of identical cryptographic keys from the first and second data profiles, anda second transceiver integrated with the second sensor and adapted to generate a second cryptographic key from a second sequence of segments of the second data profile, the first and second cryptographic keys comprising a set of identical cryptographic keys.
