1.	How Does Data Encryption Affect Index Schemes? In Particular, How Might It Affect Schemes That Attempt To Store Data In Sorted Order?
Answer» Note that indices must OPERATE on the encrypted data or someone could gain access to the index to interpret the data.Otherwise, the index would have to be RESTRICTED so that only CERTAIN users could access it. To KEEP the data in sorted order, the index scheme would have to decrypt the data at each level in a tree. Note that hash systems would not be AFFECTED.
