It is challenging to securely store and efficiently retrieve data in the military’s wireless network environment. Current distributed storage technologies must be improved to facilitate distributing the storage without vulnerability to single points of failure. Further, it would be preferable to scale the protocol and not rely on external infrastructure or pre-shared keys or complete replication. To address these issues, IAI has been awarded a contract entitled, “HAS: A Highly Available and Securely Coded Data Storage System for Wireless Mesh Networks.” HAS is a distributed data storage system that can recover the data stored in the network when a minimum number of wireless nodes are accessible. It will be secure under eavesdropping and Byzantine attacks. HAS will use erasure coding scheme, Shamir’s threshold based secret sharing algorithm and crypto primitives to securely distribute sensitive data files among network nodes and to improve the availability of data files. A secure end-to-end delivery protocol will be designed to protect the data in motion. Efficient techniques will be adopted to efficiently implement these coding schemes, crypto primitives and secure end-to-end delivery protocol. Proof of the security of integration of these schemes and protocols will be provided under the model of universal composability. Finally, these proposed techniques and concepts will be integrated in a workable data storage prototype. HAS will also have commercial applications in providing a mechanism to increase the storage capacity and reduce the security vulnerabilities of mobile devices.
