Encryption

Encryption is the mathematical transformation of data from a readable, clear text form,

into an unreadable, cipher text form. The transformation generally requires additional

secret information available only to the sender and intended recipient. This information is

called a key. The key allows the message to be encrypted by the sender, and decrypted only

by the intended recipient using the recipient’s private key. Decryption is the opposite of

encryption — it transforms unreadable, cipher text data back into readable, clear text form.

Using cryptography provides not only privacy, but it provides an identity every time a user

logs on to a network, accesses voice mail, or uses a user name and password to access

anything. This identification is called authentication. Authentication is a crucial part of

network data security.

As electronic transaction use increases over networks, it is important to sign documents

electronically. Cryptography provides the ability to create digital signatures, which in

many cases are as legally binding as written ones.

Event sink

A piece of code that is activated by a defined trigger, such as the reception of a new

message. The code is normally written in any COM-compatible programming language

such as Visual Basic, VBScript, JavaScript, C, or C++. Exchange 2000 supports the fol-

lowing event sinks:

◆Transport

◆Protocol

◆Store

Event sinks on the store can be synchronous (code executes as the event is triggered) or

asynchronous (code executes sometime after the event).

Exchange Conferencing Services – ECS

A service that allows users to meet in virtual rooms on a server running Exchange. Exchange

Conferencing Services defines the use of a Conferencing Management Service to coordinate

the room bookings and a T.120 Multipoint Control Unit (MCU) for the actual connection

of clients to a conferencing session.

Exchange Virtual Server – EVS

When clustering, you allocate different resources (such as storage groups) to an EVS. Upon

node failure, an EVS can be moved from the failed node to one of the remaining nodes.
