AbstractCDStore is a unified, multicloud storage solution for users to outsource backup data with reliability, security, and cost-efficiency guarantees. CDStore builds on an augmented secret-sharing scheme called convergent dispersal, which 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 two-stage deduplication to achieve both bandwidth and storage savings while robustly diverting side-channel attacks (launched by malicious users on the client side). A cost analysis shows that CDStore yields significant savings over baseline cloud storage solutions.
