Abstract
It is challenging to securely store and efficiently retrieve data in wireless network environment. In this effort, IAI proposes a highly available and securely coded data storage system for wireless mesh networks, called HAS, to address this challenging problem. HAS is a distributed and highly available data storage system that can recover the data stored in the network when a minimum number of wireless nodes are accessible. Moreover, HAS is secure under eavesdropping and Byzantine attacks. In HAS, we integrate erasure coding scheme, Shamir"s secret sharing algorithm and crypto primitives to securely distribute the sensitive data files among network nodes and to improve the availability of the data files. Moreover, we design a secure end-to-end delivery protocol to protect the data in motion. Additionally, we adopt efficient techniques to efficiently implement these coding schemes, crypto primitives and secure end-to-end delivery protocol in HAS. We will prove that our integration of these coding schemes, crypto primitives and secure end-to-end delivery protocol is secure under the model of universal composability. Finally, we will integrate these proposed techniques and concepts in a workable data storage prototype.
