Definitions of triple des:

Data Encryption Standard (DES) is a widely-used method of data encryption using a private (secret) key that was judged so difficult to break by the US government that it was restricted for exportation to other countries. There are 72,000,000,000,000,000 (72 quadrillion) or more possible encryption keys that can be used. For each given message, the key is chosen at random from among this enormous number of keys. ...

A variant of DES in which data is encrypted three times with standard DES using two different keys.
howtos.linux.com/howtos/Kerberos-Infrastructure-HOWTO/g477.shtml
A method of vastly increasing the security of DES by encrypting 3 times with different keys.
www.efa.org.au/Issues/Crypto/crypto5.html
Each block is encrypted three times using DES, using at least two different keys. There are variants which differ in whether two or three keys are used, and whether some of the steps are in decryption mode. In SSL, three separate keys are used, and the middle step is a decryption.

increases the security provided by DES (Data Encryption Standard) by extending the key space to 112 or 168 bits, but requires multiple passes and takes more time.

Triple DES is simply another mode of DES operation. It takes three 64-bit keys, for an overall key length of 192 bits. The procedure for encryption is exactly the same as regular DES, but it is repeated three times. Hence the name Triple DES. The data is encrypted with the first key, decrypted with the second key, and finally encrypted again with the third key.

(Used for ESP) A simple variant on the DES-CBC algorithm in which three rounds of DES are performed -- an encryption process followed by a decryption process followed by an encryption process, where each process uses an independent key. Top
www.sequi.com/SEQUI_VPN_Glossary.htm
A block cipher, based on DES, that transforms each 64-bit plaintext block by applying the Data Encryption Algorithm three successive times, using either two or three different keys, for an effective key length of 112 or 168 bits. TDES is a US Government FIPS approved algorithm when implemented as specified in FIPS 46-3.

An encryption configuration in which the DES algorithm is used three times with three different keys.

An enhanced version of DES that allows for more security than DES alone. Triple DES uses three keys and encrypts three times.

In cryptography, Triple DES (also 3DES) is a block cipher formed from the Data Encryption Standard (DES) cipher. It was developed by Walter Tuchman (the leader of the DES development team at IBM) and is specified in FIPS Pub 46-3. There are several ways to use DES three times; not all are Triple-DES and not all are as secure.
