A Novel Data Encryption and Distribution Approach for High Security and Availability Using LU Decomposition

摘要

As the society increasingly relies on digitally stored and accessed information, supporting the availability, persistence, integrity, and confidentiality of the information becomes more critical. Mirroring is a simple but practical approach allowing reasonable availability and accessibility, but it cannot provide security. This paper proposes an approach which integrates data encryption and distribution to allow high security while providing the same degree of availability as mirroring. It is based on LU decomposition of matrix. Analysis confirms that it allows slightly higher availability compared with mirroring scheme for both read and write operation. The proposed scheme needs almost the same storage space as mirroring.
