WEP, WPA, WPA2, and PEAP are all wireless security protocols.
- WEP (Wired Equivalent Privacy) is the oldest and least secure of these protocols. It uses a 64-bit or 128-bit key that can be easily cracked by hackers.
- WPA (Wi-Fi Protected Access) was introduced as a replacement for WEP. It uses a stronger encryption algorithm called TKIP (Temporal Key Integrity Protocol). However, WPA is still vulnerable to attacks, such as the Key Reinstallation Attack (KRACK).
- WPA2 (Wi-Fi Protected Access 2) is the most secure of these protocols. It uses the more secure encryption algorithm AES (Advanced Encryption Standard). WPA2 is also resistant to the KRACK attack.
- PEAP (Protected Extensible Authentication Protocol) is an authentication framework that can be used with WPA or WPA2. It provides additional security by wrapping the EAP authentication traffic in an encrypted tunnel.
In general, you should use WPA2 or PEAP if possible. WEP should only be used if it is the only option available.
Here is a table summarizing the key differences between these protocols:
Protocol | Encryption Algorithm | Key Length | Security |
---|---|---|---|
WEP | RC4 | 64 or 128 bits | Low |
WPA | TKIP | 128 bits | Medium |
WPA2 | AES | 128 or 256 bits | High |
PEAP | TKIP or AES | 128 or 256 bits | High |
