Abstract

Securedand reliable data storage and transport, such as private information in utility bills, are among many important concerns on smart grid. Instead of utilizing separated encryption and redundancy techniques, we choose wavefront multiplexing/demultiplexing process (WF muxing/demuxing) utilizing multi-dimensional transmissions to perform both security and reliability for data storage and transport. Multiple data sets are preprocessed by a WF muxing transformation, in which multiple data sets have been "orthogonally processed" and disassembled into any scalable number of sets of processed data, with each set being stored on a storage site or transported to destinations. The original data is reassembled via a WF demuxing transformation after retrieving a lesser but scalable number of WF muxed data sets.
