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. Benefits: SD2S is designed for DDS (Distributed Data Storage) in a hostile wireless ad hoc network. Our market analysis shows that SD2S has many applications that can be used. The applications include the military wireless ad hoc networks (e.g., Dismounted Tactical Edge Network) and remotely operated systems where DDS is a must-have technology to protect the sensitive data. SD2S can be developed for COTS/GOTS products to provide the DDS capabilities: (i) data protection from being compromised, (iii) data resiliency, and (iii) data recoverability in a hostile environment. SD2S software products will be developed in such a way that SD2S can be accommodated in the cheap mobile devices. It provides a means for mobile soldiers to conduct ubiquitous data storage and access in the network to protect the non-volatile storage of a collection of mobile devices. SD2S can also be developed as COTS/GOTS for commercial wireless ad hoc networks. SD2S software is installed at the mobile devices such as underwater vehicles, robots, underwater phones to enhance the data storage capability without the intervention of human being. The Navy would gain significant values from the commercialized dual-use SD2S products. By providing flexible production designs, the marketing cost can be reduced through an economical license model that offers attractive development, demonstration, and production options. The use of SD2S would increase return-on-investment through adding values to existing Navy systems. The SD2S design would enable rapid technology transition and commercialization success. Our effort is to attract a great amount of investment and transition our SD2S technology into actual products. We will closely work with our partners (Alcatel-Lucent, AT&T, and Microsoft) to rapidly transfer this technology into the military and commercial worlds. Return
