Triple DES

In cryptography, Triple DES is the common name for the Triple Data Encryption Algorithm (TDEA or Triple DEA) block cipher, which applies the Data Encryption Standard (DES) cipher algorithm three times to each data block.

The original DES cipher's key size of 56 bits was generally sufficient when that algorithm was designed, but the availability of increasing computational power made brute-force attacks feasible. 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.

Famous quotes containing the words des and/or triple:

    One difference between Nazi and Soviet camps was that in the latter dying was a slower process.
    —Terrence Des Pres (1939–1987)

    Their martyred blood and ashes sow
    O’er all the Italian fields where still doth sway
    The triple tyrant; that from these may grow
    A hundredfold, who, having learnt thy way,
    Early may fly the Babylonian woe.
    John Milton (1608–1674)
