PROJECT TITLE:

CDStore Toward Reliable, Secure, and Cost-Efficient Cloud Storage via Convergent Dispersal - 2016

ABSTRACT:

CDStore is a unified, multicloud storage answer for users to outsource backup knowledge with reliability, security, and price-efficiency guarantees. CDStore builds on an augmented secret-sharing scheme referred to as convergent dispersal, that supports deduplication by using deterministic, content-derived hashes as input to secret sharing. CDStore's design is presented here, with an emphasis on how it combines convergent dispersal with 2-stage deduplication to attain both bandwidth and storage savings whereas robustly diverting facet-channel attacks (launched by malicious users on the client aspect). A price analysis shows that CDStore yields significant savings over baseline cloud storage solutions.
