Triple DES (Triple Data Encryption Standard) More correctly known as Triple Data Encryption Algorithm (TDEA). A block cipher encryption method that uses the DES encryption algorithm to encrypt message blocks three times, using three different 56-bit keys. Triple DES is highly secure, but slow, and largely has been superseded by Advanced Encryption Standard (AES). See also AES, algorithm, block, DES, encryption, and key. |
