Methods for the generation of identical symmetrical cryptographic keys

摘要

Methods and algorithms for generating identical symmetrical cryptographic keys. In a method for generating a symmetrical cryptographic key, a first profile is generated, the first profile comprising a series of data points collected over a first period of time. A start time of the first profile is identified and the first profile divided into a sequence of time-based segments, each time-based segment comprising at least one data point. A first symmetrical cryptographic key is calculated from the sequence of time-based segments, and the first symmetrical cryptographic key is stored for at least one of encrypting and decrypting data in cooperation with a second symmetrical cryptographic key substantially identical to the first symmetrical cryptographic key.

1. A method for exchanging cryptographically encoded data comprising:
obtaining a data profile by a sensing element integrated with a transceiver in each of a plurality of devices; calculating an identical symmetrical cryptographic key from the data profile by the transceiver in each of the plurality of devices by
dividing the data profile into a plurality of sements,determining a plurality of weight factors, one for each of the plurality of segments, by comparing, the plurality of segments with at least one sample,providing the plurality of weight factors to a hash function,combining the plurality of weight factors into a plurality of groups,assigning a number to each of the plurality of groups, andcreating the identical symmetrical cryptographic key from the number assigned to each of the plurality of groups; and using the identical symmetrical cryptographic key to encrypt and decrypt data in the transceiver in each of the plurality of devices, in communications among the plurality of devices.
