What underlying symmetric encryption cipher does WEP use?
Understand the Problem
The question is asking about the symmetric encryption cipher that is used in WEP (Wired Equivalent Privacy). It seeks to identify the specific cryptographic algorithm employed within the WEP protocol to secure wireless communication.
Answer
RC4
The final answer is RC4

The final answer is RC4
More Information
Wired Equivalent Privacy (WEP) uses the RC4 (Rivest Cipher 4) stream cipher for encryption. This was intended to provide comparable confidentiality to a wired network. However, WEP has known vulnerabilities and has been largely replaced by more secure protocols like WPA and WPA2.
Tips
A common mistake is confusing WEP with WPA2, which uses AES. WEP specifically uses RC4.
