A wireless device is set to look for beacon frames from the AP. This is known as ____________________.

To encrypt packets WEP can use only a 64-bit or ____-bit number.

What is a MAC address?

Describe the main characteristics of the shared key authentication method.

What are the differences between Dynamic WEP unicast and broadcast keys?

In WEP, RC4 uses a(n) ____________________ to create the keystream.

WEP2 uses a different authentication system known as ____.

____ solves the weak initialization vector (IV) WEP problem by rotating the keys frequently.

The IEEE standard specifies that the access points and devices can hold up to four shared secret keys, one of which must be designated as the ____________________.

Changing the original text to a secret message using cryptography is known as ____.

____________________ is the science of transforming information so that it is secure while it is being transmitted or stored.

When WEP is used for shared key authentication it is serving a dual function of encryption and authentication.

A stream cipher takes one character and replaces it with another character. This output is known as the ____.

Briefly explain how turning off the beaconing of the SSID affects roaming in a wireless network environment.

____ was developed by the Massachusetts Institute of Technology (MIT) and used to verify the identity of network users.

Describe the main characteristics of the open system authentication method.

In ____, a shared secret key is used to encrypt the cleartext as well as decrypt the ciphertext.

WEP relies on a secret key shared between a wireless client device and the access point.

With ____ scanning a wireless device simply listens for a beacon frame for a set period of time.
