Wireless Encryption

This is done by scrambling the data into ciphertext using a master key created from the networks SSID and password.

Data is decrypted by the receiver using the same master key- the key is not transmitted.

Wireless networks broadcast data that needs to be encrypted to be secure from unauthorised users

Wireless encryption protocols include WEP,WPA and WPA2. A handshake protocol is used to ensure the user has a valid master key before transmission begins.
