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

Cipher that applies the DES cipher three times with either two or three different DES keys.

a symmetric key cryptography algorithm based on DES (Data Encryption Standard). Each block is encrypted three times using two or three keys. This increases security by extending the key to 112 or 168 bits.

A method of increasing the security of Data Encryption Standard by encrypting 3 times with different keys.

a method of improving the security of the DES algorithm by using it three times in sequence with different keys.

A cryptographic algorithm for repeated DES operations that have the effect of increasing the security of the encrypted message. American National Standards Institute, ANSI X9.52-1998, "Triple Data Encryption Algorithm Modes of Operation"

Triple DES encryption means encrypting data three times instead of one. The most common form of triple DES encrypts data once using one key, decrypts the results using a second key, and then encrypts again using a third key.

A variant of the original Data Encryption Standard that doubles the effective security. Often abbreviated as 3DES. The security level of 3DES is still considered to be very high, but there are faster block ciphers that provide comparable levels of security, such as AES.

A common encryption algorithm based on DES. Three times slower but far more secure.

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.

A data encryption algorithm based on DES in which information is processed through the DES algorithm three times.

See 3DES.

An algorithm that uses DES and either one, two, or three keys to encrypt/decrypt/encrypt packets of information.

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.

A 168-bit encryption algorithm that encrypts each piece of data with three different DES keys in succession, providing a higher level of encryption.

A variation of the DES block cipher algorithm that encrypts plain text with one key, encrypts the resulting ciphertext with a second key, and finally, encrypts the result of the second encryption with a third key. Triple DES is a symmetric algorithm that uses the same algorithm and keys for encryption and decryption.

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

Encrypting plaintext with DES three times, effectively lengthening the DES secret key to 3 * 56 =168 bits, which is more secure than both single and double DES.

In cryptography, Triple DES is a block cipher formed from the Data Encryption Standard (DES) cipher by using it three times.
