You can create a pseudo-index of your data by adding an additional column to your table with a one-way hash code of your plain text, and creating an index on that column The built-in SQL Server 2008 HashBytes function can be used to generate a one-way MD5, SHA-1, or other hash value of your plain text and store it in the new column Indexing this new plain text hash value column can make equality searches (using the T-SQL = operator) much more efficient Range searches (operators like <, >, BETWEEN, and so on), however, cannot be used on hashed or encrypted data One of the implications of pseudo-indexing with a hash value is that it once again opens the door for statistical analysis attacks using the hash values as a guide Using a hash value as an index.

also makes dictionary attacks against the hashed values possible. A dictionary attack is one in which a hacker uses a large list of plain text values to try to guess the plain text of a hashed or an encrypted value by brute force. Another method of pseudo-indexing encrypted data is a variation on the previous method, except that it uses a hashed message authentication code (HMAC) in place of the hash value. The HMAC basically takes a secret value, combines it with the plain text, and generates a hash value based on that data. Although the HMAC method provides protection against dictionary attacks, it doesn t provide any additional protection against statistical analysis.

The only difference between this and the previous expansion is that this also assigns a value to var: $ var= $ echo "${var:=q}" q $ echo "${var:=z}" q

SQL Server Engine team member Raul Garcia provides an excellent example of using an HMAC code to create an index on your encrypted data in his blog (http://blogs.msdn.com/raulga).

To get started, create the contact module using the Zend Tool Project s create module command, as shown in Listing 10-1. This will create the module directory and the required subdirectories. Listing 10-1. Creating the Contact Module with Zend Tool Project zf create module contact Now you need to create the contact controllers and views manually. First create the index controller. Add a new file to the application/modules/contact/controllers directory named IndexController.php. Open this file, and add the controller class. Note that the class names of the module controllers are prepended with the module namespace, so in this case the controller class name should be Contact_IndexController. Add an empty indexAction() method to this controller, as shown in Listing 10-2. Listing 10-2. The Contact Module s IndexController in application/modules/contact/controllers/IndexController.php < php class Contact_IndexController extends Zend_Controller_Action

The main thing to consider when using SQL Server s data-encryption facilities is that encryption and search efficiency are opposing goals. The purpose of encryption is data security, often at the expense of search efficiency. While you can use the methods suggested here to increase the efficiency of SQL queries on encrypted data, the hash value and HMAC index methods require more storage and can actually circumvent SQL Server s protection against statistical analysis (via random IV).
