Explanation

3DES (Triple DES) is a symmetric encryption algorithm that applies the Data Encryption Standard (DES) cipher three times to each data block. It was developed to address weaknesses in the original DES by using multiple encryption rounds with different keys.

AI explanation

3DES (Triple DES) applies the original DES block cipher algorithm three times in sequence to each data block (typically encrypt-decrypt-encrypt with three keys, EDE mode), which was developed to extend the effective key length of the aging 56-bit DES cipher without designing an entirely new algorithm, since DES alone became vulnerable to brute-force attacks. 'Triple Disk Encryption/Encoding System' are fabricated expansions that don't match the actual cryptographic term, and '3 DES' is just the acronym restated without expansion, not what the acronym stands for. 'Triple DES' is the correct, standard expansion.
