Concepts inCryptDB: protecting confidentiality with encrypted query processing

Confidentiality

Confidentiality is an ethical principle associated with several professions (e.g. , medicine, law, psychotherapy). In ethics, and (in some places) in law and alternative forms of legal resolution such as mediation, some types of communication between a person and one of these professionals are "privileged" and may not be discussed or divulged to third parties.  more from Wikipedia

Encryption

In cryptography, encryption is the process of transforming information (referred to as plaintext) using an algorithm to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. The result of the process is encrypted information (in cryptography, referred to as ciphertext). The reverse process, i.e. , to make the encrypted information readable again, is referred to as decryption (i.e. , to make it unencrypted).  more from Wikipedia

Query optimization

Query optimization is a function of many relational database management systems in which multiple query plans for satisfying a query are examined and a good query plan is identified. This may or not be the absolute best strategy because there are many ways of doing plans. There is a trade-off between the amount of time spent figuring out the best plan and the amount running the plan. Different qualities of database management systems have different ways of balancing these two.  more from Wikipedia

Database administrator

A database administrator (short form DBA) is a person responsible for the installation, configuration, upgrade, administration, monitoring and maintenance of physical databases. The role includes the development and design of database strategies, monitoring and improving database performance and capacity, and planning for future expansion requirements. They may also plan, co-ordinate and implement security measures to safeguard the database.  more from Wikipedia

PhpBB

phpBB is a popular Internet forum package written in the PHP scripting language. The name "phpBB" is an abbreviation of PHP Bulletin Board. Available under the GNU General Public License, phpBB is free and open source software.  more from Wikipedia

Column (database)

In the context of a relational database table, a column is a set of data values of a particular simple type, one for each row of the table. The columns provide the structure according to which the rows are composed. The term field is often used interchangeably with column, although many consider it more correct to use field (or field value) to refer specifically to the single item that exists at the intersection between one row and one column.  more from Wikipedia

MySQL

MySQL is the world's most used relational database management system (RDBMS) that runs as a server providing multi-user access to a number of databases. It is named after co-founder Michael Widenius' daughter, My. The SQL phrase stands for Structured Query Language. The MySQL development project has made its source code available under the terms of the GNU General Public License, as well as under a variety of proprietary agreements.  more from Wikipedia

Password

A password is a secret word or string of characters that is used for authentication, to prove identity or gain access to a resource . The password should be kept secret from those not allowed access. The use of passwords is known to be ancient. Sentries would challenge those wishing to enter an area or approaching it to supply a password or watchword. Sentries would only allow a person or group to pass if they knew the password.  more from Wikipedia
