Communication systems, transceivers, and methods for generating data based on channel characteristics
| DWPI Title: Method for generating private shared data for use in e.g. public-key cryptography, involves associating each region with respective symbols, and combining identified symbols to generate data stored in electronic storage medium |
| Abstract: Examples of methods for generating data based on a communications channel are described. In one such example, a processing unit may generate a first vector representation based in part on at least two characteristics of a communications channel. A constellation having at least two dimensions may be addressed with the first vector representation to identify a first symbol associated with the first vector representation. The constellation represents a plurality of regions, each region associated with a respective symbol. The symbol may be used to generate data, which may stored in an electronic storage medium and used as a cryptographic key or a spreading code or hopping sequence in a modulation technique. |
| Use: Method for generating private shared data for use in public-key cryptography and secure modulation. |
| Advantage: The private shared data can be generated between nodes in communication system for secure modulation so as to generate hopping sequence or spreading code in secure modulation scheme. |
| Novelty: The method involves measuring characteristics of communication channel (115), and converting measured characteristics into respective vector representation. Constellations having dimensions with respective vector representation is addressed to identify respective symbols associated with respective vector representation. The addressed constellations are configured to represent several regions, and each region is associated with respective symbols. The identified symbols are combined to generate data that is stored in electronic storage medium. |
