A Distributed Data Storage Scheme for Sensor Networks

Free registration required

Executive Summary

The authors present a data storage scheme for sensor networks that achieves the targets of encryption and distributed storage simultaneously. They partition the data to be stored into numerous pieces such that at least a specific number of them have to be brought together to recreate the data. The procedure for creation of partitions does not use any encryption key and the pieces are implicitly secure. These pieces are then distributed over random sensors for storage. Capture or malfunction of one or more (less than a threshold number of sensors) does not compromise the data.
