Data Encryption Standard. A federally approved symmetric encryption 
algorithm in use for many years and replaced by the Advanced 
Encryption Standard (AES). See also 3DES.

Dynamic Host Configuration Protocol. A protocol that dynamically 
assigns IP addresses to stations, from a centralized server. DHCP is the 
successor to the Bootstrap Protocol (BOOTP).

An attempt to gain illegal access to a computer or network by logging 
in repeatedly with passwords that are based on a list of terms in a 
dictionary.

A key exchange algorithm that was the first public-key algorithm ever 
published. Diffie-Hellman can be used anonymously (without 
authentication). Anonymous Diffie-Hellman is used to establish the 
connection between the 3Com Wireless Switch Manager (3WXM) and 
a Wireless Switch (WX).

Differentiated services. An architecture for providing different types or 
levels of service for network traffic. Diffserv aggregates flows in the 
network so that routers and switches need to distinguish only a 
relatively small number of aggregated flows, even if those flows contain 
thousands or millions of individual flows.

A document containing the name of a user (client) or server, a digital 
signature, a public key, and other elements used in authentication and 
encryption. See also X.509.

The result of encrypting a hash of a message or document with a 
private key. A digital signature is used to verify the authenticity of the 
sender and the integrity (unaltered condition) of the message or 
document. See also hash.

See DSA.

See DSSS.

(1) On the Internet, a set of network addresses that are organized in 
levels. (2) In Microsoft Windows NT and Windows 2000, a set of 
network resources (applications, printers, and so forth) for a group of 
users (clients). Clients log into the domain to access the resources, 
which can be located on a number of different servers in the network.
