CNET GLOSSARY: Terms for the techie
A data encryption standard. As its name suggests, 3DES is a three-step data encryption algorithm that evolved from DES. 3DES provides greater security than DES because it encrypts, decrypts, and encrypts the data using three keys instead of just one. The size of a 3DES key is also three times bigger: 168 bits to 56 bits for DES.
