2.2 – Wireless Encryption Protocols Flashcards
1
Q
- WPA [WiFi Protected Access]
A
o Is more secure than WEP but still vulnerable
o Users authenticate using an alphanumeric passphrase [PSK = Pre-Secured Key / WiFi password] via TKIP = Temporal Key Integrity Protocol
o Encrypts with RC4 = Rivest Cipher 4
o It takes about 15 mins to crack [DON’T USE]
2
Q
- WEP = Wired Equivalency Privacy
A
o Should NOT be used
o Easily cracked
3
Q
- WPA2 [WiFI Protected Access 2]
A
o More secure than WEP & WPA
o Authentication using PSK via CCMP = Counter Mode Cipher-block Chaining Message authentication code Protocol
o Encrypts with AES = Advance Encryption Standard
o Use at a bare minimum
o Really crackable
4
Q
- WPA3 [WiFi Protected Access 3]
A
o The MOST secure
o Users authenticate using SAE = Simultaneous Authentication of Equals which combines PSK with client’s MAC address
o Encrypts with AES = Advance Encryption Standard
o Not many routers support it
