Secure Fragment Allocation in a Distributed Storage System With Heterogeneous Vulnerabilities

There is a growing demand for large-scale distributed storage systems to support resource sharing and fault tolerance. Although heterogeneity issues of distributed systems have been widely investigated, little attention has yet been paid to security solutions designed for distributed storage systems with heterogeneous vulnerabilities. This fact motivates one to investigate a fragment allocation scheme called S-FAS to improve security of a distributed system where storage sites have a wide variety of vulnerabilities. In the S-FAS approach, the authors integrate file fragmentation with the secret sharing technique in a distributed storage system with heterogeneous vulnerabilities.
