Product Description

Dictionary Based Secure Provenance Compression for Wireless Sensor Networks

The data provenance for the wireless sensor networks (WSNs) is crucial due to energy and bandwidth limitations of wireless sensor networks (WSNs). Even if lossy compression techniques are used for encoding provenance information, the size of the provenance increases with the number of nodes traversed by the network packets. To address such issues, a dictionary based provenance scheme is proposed.

In the proposed system each sensor node in the network stores a packet path dictionary. With the support of this dictionary, a path index instead of the path itself is enclosed with each packet. Since the packet path index is a code word of a dictionary, its size is independent of the number of nodes present in the packet’s path.

The proposed system also binds the packet and its provenance through an AM-FM sketch and uses a secure packet sequence number generation technique, and can defend against most of the known provenance attacks.

Through simulation and experimental results, the proposed scheme outperforms other compact provenance schemes with respect to provenance size, robustness, and energy consumption.
