Final answer:
WEP (Wired Equivalent Privacy) uses the RC4 encryption algorithm, but none of the options provided (GGMP, TKIP, AES, CCMP) are associated with WEP. There might be an error in the question as these options relate to more modern encryption protocols such as those used by WPA and WPA2.
Step-by-step explanation:
The encryption provided by WEP (Wired Equivalent Privacy) is achieved using the RC4 stream cipher for confidentiality, and CRC-32 checksum for integrity. The options given include different protocols and algorithms related to wireless encryption, but the one used by WEP is not explicitly listed among your choices (GGMP, TKIP, AES, CCMP). If these are the only options you can choose from for the answer, then it's possible that there might be a mistake in the question or the list of options. Historically, WEP has been deemed insecure due to its vulnerability to numerous attacks, and it has largely been replaced by more secure encryption methods like WPA2 (which uses CCMP and AES) and WPA3.
