Abstract: This talk will provide an overview of our recent research efforts on the design, analysis, and implementation of efficient and secure codes for distributed storage systems. First, we discuss constructions of weakly secure codes that aim to hide information about individual packets as well as small groups of packets from an eavesdropper. Weakly secure codes do not use random keys, and, as a result, have better performance and lower overhead than the traditional schemes.
Next, we discuss the design and analysis of codes of distributed storage codes with certain locality constraints. Inspired from the notion of unequal error protection, we are focus on unequal locality codes, in which, different subsets of symbols have different locality requirements.
Finally, we discuss a new architecture that leverages coding technique to improve the performance of Storage Area Networks. The key idea of our approach is to extend the capabilities of Software-Defined Networking (SDN)-enabled switches to allow them to perform both traditional forwarding operations as well as new encoding operation.
