Which wireless security standard uses dynamic encryption keys and supports public key authentication?
1. WEP
2. MAC filtering
3. >>WPA
4. 802.1x
Explanation : The most secure wireless security standard is 802.1x, which offers a dynamic encryption key and supports a number of authentication methods, through Extensible Authentication Protocol (EAP), including certificates, public keys, and Kerberos.
Wired Equivalent Privacy (WEP) requires that you manually change encryption keys. It also does not support public key authentication.
Media Access Control (MAC) filters can be used to allow only certain computers to access a wireless access point secured using WEP. Access is granted or denied based on the MAC address.
Wi-Fi Protected Access (WPA) changes the key every 10,000 packets using a mechanism called Temporal Key Integrity Protocol (TKIP). It does not, however, support public key authentication.
