Encryption
Definition
Encryption involves using a password to encode data sent over a wireless network
in order to make the data unintelligible to eavesdroppers. Only devices that know
the password can decode the data.
Types of encryption
The printer supports four types of encryption. Each type of encryption has its
benefits and limitations.
Encryption type Description Benefits Limitations
Devices on a
network do not
encrypt data.
Least complicated
strategy.
Provides no
protection against
eavesdroppers.
WEP
encryption
Devices on a
network share a
password, called a
“WEP key” to
encode and decode
data.
Simplest strategy
that provides
encryption.
All devices must
have the key.
The WEP key does
not change
automatically.
WEP encryption
provides less
security than both
AES or TKIP.
