There are multiple Wi-Fi security protocols for personal and enterprise networks:
• Wired Equivalent Privacy (WEP), introduced as part of the original 802.11 standard ratified in 1997.
It uses the RC4 cipher to ensure confidentiality and a CRC-32 Checksum to ensure integrity of the
data transmitted.
• Wi-Fi Protected Access (WPA) became available in 2003. It was the replacement to the increasingly
apparent vulnerabilities of the WEP encryption standard. The keys used by WPA are 256-bit, a
significant increase over the 64-bit and 128-bit keys used in the WEP system. WPA includes message
integrity checks and the Temporal Key Integrity Protocol (TKIP). TKIP employs a per-packet key
system that was radically more secure than the fixed key system used by WEP. RC4 cipher is still
used to ensure confidentiality in WPA.
