What is a static WEP key?

Static WEP is not the most secure mode available, but it offers more protection than setting the security mode to None (Plain-text) as it does prevent an outsider from easily sniffing out unencrypted wireless traffic. WEP encrypts data moving across the wireless network based on a static key.

Which wireless security standards uses a 128-bit key?

The WPA protocol implements the Temporal Key Integrity Protocol (TKIP). WEP used a 64-bit or 128-bit encryption key that must be manually entered on wireless access points and devices and does not change.

What is a 24 bit IV?

The purpose of an IV, which is transmitted as plain text, is to prevent any repetition, but a 24-bit IV is not long enough to ensure this on a busy network. The way the IV was used also opened WEP to a related key attack. For a 24-bit IV, there is a 50% probability the same IV will repeat after 5,000 packets.

Which wireless security standards uses a 128-bit key quizlet?

In what way does Wi-Fi Protected Access (WPA) improve upon Wired Equivalent Privacy (WEP)? It uses the Temporal Key Integrity Protocol (TKIP), which provides a 128-bit encryption key.

How many characters are in a 128 bit WEP key?

A 128-bit WEP key is usually entered as a string of 26 hexadecimal characters. Twenty-six digits of four bits each equals104 bits; if you add the 24-bit IV, it produces the complete 128-bit WEP key. Most devices allow the user to enter the key as 13 ASCII characters.

How do you write a 64 bit WEP key?

A 64-bit WEP key is usually entered as a string of 10 hexadecimal (base 16) characters (zero through nine and A-F). Each character represents four bits, and ten digits of four bits each equals 40 bits; if you add the 24-bit IV, it produces the complete 64-bit WEP key.

How secure is WEP encryption?

Remember, WEP actually uses an encryption key of either 64 or 128 bits, using only hexadecimal characters (0-9, A-F). This length of a key is not very secure with the amount of computing power that people have in their pockets. WEP is not a good encryption standard; however, it is better than no security.

What is the WEP key used for?

With Shared Key Authentication, the WEP key is used for authentication in a four-step, challenge-response handshake: The client sends an authentication request to the AP. The AP replies with a clear-text challenge. The client encrypts the challenge-text with the configured WEP key, and responds with another authentication request.
