Ensuring security of the column-store become more and more important with the popularity of column-store as a promising physical design alternative in recent years. Because the structure features of the column-store differ from the traditional row-store, new encryption schemes which are suitable for column-store must be found to guarantee the security of column-store. The authors analyze the existing encryption scheme of column-store, and according to the structure features of column-store, propose a new column-store encryption scheme Romega which bases on Multistage Interconnection Network (MIN), and analyze the security and efficiency of this encryption scheme.
