Data Storage and Transmission Strategies for Wireless Ad Hoc Networks

In the tactical wireless ad hoc network, all networking nodes are vulnerable to various security attacks. Therefore, the centralized data storage is unable to protect the tactical data once the storage device is compromised by an adversary. Distributed data storage is the alternative that the data are securely and reliably spread on the networking nodes with certain redundancy, offering high data protection and data resiliency. In this project, we developed Secure Distributed Data Storage (SD2S) by using Secret Share (SS) algorithm and Elliptic Curve Cryptography (ECC) for mobile ad hoc networks. SD2S is a novel (n, t) data storage system where the proposed SS algorithm coverts the data into n shares. Each share leaks nothing on the data and the original data can only be recovered from t shares. ECC provides an additional layer of data protection. The data is protected even if all the shares are compromised by the adversary. SD2S can be used for unsecure storage nodes (e.g., unsecure wireless links and hostile storage nodes). The internal and external attacks on distributed storage system are investigated to prevent potential adversaries. SD2S is superior to all other existing approaches in terms of data protection and performance efficiency.
