DES encryptions, 2. Biham: find one of 2. In cryptography, Triple DES (3. DES), officially the Triple Data Encryption Algorithm (TDEA or Triple DEA), is a symmetric- keyblock cipher, which applies the Data Encryption Standard (DES) cipher algorithm three times to each data block.
The original DES cipher's key size of 5. Triple DES provides a relatively simple method of increasing the key size of DES to protect against such attacks, without the need to design a completely new block cipher algorithm. Definitive standards. FIPS PUB 4. 6- 3 (1. ISO/IEC 1. 80. 33- 3 (2. The encryption algorithm is: ciphertext = EK3(DK2(EK1(plaintext)))I. DES encrypt with K1, DES decrypt with K2, then DES encrypt with K3.
Decryption is the reverse: plaintext = DK1(EK2(DK3(ciphertext)))I. K3, encrypt with K2, then decrypt with K1.

Each triple encryption encrypts one block of 6. In each case the middle operation is the reverse of the first and last. This improves the strength of the algorithm when using keying option 2, and provides backward compatibility with DES with keying option 3. Keying options. K1 = K2 = K3. Keying option 1 is the strongest, with 3 .
This option is stronger than simply DES encrypting twice, e. It provides backward compatibility with DES, because the first and second DES operations cancel out. It is no longer recommended by the National Institute of Standards and Technology (NIST).

This is not currently practical and NIST considers keying option 1 to be appropriate through 2. Thus X9. 5. 2 must be read in conjunction with X3. United States Department of Commerce (1.
