Numeric
3DES
3DES (Triple DES) achieves a high level of security by encrypting the data three times using DES with three
different, unrelated keys.
A
ADSL
Short for asymmetric digital subscriber line, a technology that allows data to be sent over existing copper
telephone lines at data rates of from 1.5 to 9 Mbps when receiving data (known as the downstream rate) and
from 16 to 640 Kbps when sending data (known as the upstream rate).
ADSL requires a special ADSL modem. ADSL is growing in popularity as more areas around the world
gain access.
Address Resolution Protocol
An Internet Protocol that dynamically maps Internet addresses to physical (hardware) addresses on a LAN.
AES
Advanced Encryption Standard, a symmetric 128-bit block data encryption technique.
It is an iterated block cipher with a variable block length and a variable key length. The block length and the
key length can be independently specified to 128, 192 or 256 bits.The U.S government adopted the
algorithm as its encryption technique in October 2000, replacing the DES encryption it used. AES works at
multiple network layers simultaneously.
AH
Authentication Header.
API
