Boosting Degraded Reads in Heterogeneous Erasure-Coded Storage Systems

Distributed storage systems provide large-scale data storage services, yet they are confronted with frequent node failures. To ensure data availability, a storage system often introduces data redundancy via replication or erasure coding. As erasure …

On the Speedup of Recovery in Large-Scale Erasure-Coded Storage Systems

Modern storage systems stripe redundant data across multiple nodes to provide availability guarantees against node failures. One form of data redundancy is based on XOR-based erasure codes, which use only XOR operations for encoding and decoding. In …

A Tag Encoding Scheme against Pollution Attack to Linear Network Coding

Network coding allows intermediate nodes to encode data packets to improve network throughput and robustness. However, it increases the propagation speed of polluted data packets if a malicious node injects fake data packets into the network, which …
