Abstract
When the traditional encryption algorithms are applied to the database, efficiency degradation occurs because the orders of ciphertext and plaintext are not the same. Therefore, the encryption mechanisms suitable for database environment are required. We propose an encryption mechanism that can support range queries without exposing the order of plaintext. This method is more powerful than the previous order-preserving methods and is expected to handle data more efficiently than other methods including auxiliary B+-tree. © 2007 IEEE.
