Block-Level Storage Security Architectures

With the unprecedented growth of storage systems in all of today’s society, threats on stored sensitive information have become the critical issues that need to be addressed. Further, compared to the transient risks of data in-flight, the risks associated with data-at-rest are more enduring. While there have been many strategies and mechanisms to implement storage security on data-at-rest, these solutions implemented on application level or operating system level have several shortcomings, including weak security and heavy burden on sever load. In this paper, we propose two hardware security structures based on block level, namely, store-and-forward architecture and cut-through architecture. In our approach, we design and implement these architectures based on FPGA. Our experimental results show that our schemes achieve transparency and completeness in real time without decreasing performance of system.
