Which protocol does WEP use to encrypt data?

• A. AES encryption
• B. RC4 encryption
• C. SHA-256 encryption
• D. RSA encryption

Answer: (B)

Wired Equivalent Privacy (WEP) uses RC4 encryption to secure data transmitted over wireless networks. RC4 is a stream cipher that was chosen for its simplicity and speed, making it well-suited for the wireless environments WEP was designed to protect. The primary role of WEP is to provide a level of security similar to what one would expect from a wired network. RC4 operates by generating a pseudo-random key stream that is XORed with the plaintext data to produce the ciphertext. This process is foundational to how WEP aims to protect data confidentiality over wireless connections. Other protocols mentioned, such as AES, SHA-256, and RSA, pertain to different types of encryption and purposes. AES is a symmetric encryption standard that provides stronger security than WEP but is not utilized by WEP. SHA-256 is a hashing algorithm, which is used for ensuring data integrity rather than encryption, and RSA is an asymmetric encryption algorithm often used for secure key exchange rather than for encrypting data directly in the manner WEP does. Hence, understanding that WEP specifically relies on RC4 is crucial for grasping the broader scope of wireless security protocols and their historical significance.
