Security Problem in Cluster Distributed Storage Systems: Regenerating Code Against Two General Types of Active Adversaries

This research examines security vulnerabilities in clustered distributed storage systems (CDSSs, which are networks of computers that store data across multiple machines organized into groups), focusing on attacks by two types of adversaries: omniscient adversaries (attackers with complete knowledge of the system) and limited-knowledge adversaries (attackers with partial information). The study analyzes how these attackers can compromise the system by sending corrupted data during file reconstruction and repair, and proposes theoretical bounds on system resilience using coding techniques.
