質問 # 166
In an RSN requiring low-latency reassociations and no fast secure roaming protocols, what security solutions are ideal for protecting VoWiFi communication?(Choose all that apply.) Response:

A. WEP
B. WPA-Personal
C. WPA2-Personal
D. 802.1X/EAP
E. WPA2-Enterprise

正解：C、E

解説：
WPA2-Personal and WPA2-Enterprise are ideal security solutions for protecting VoWiFi communication in an RSN requiring low-latency reassociations and no fast secure roaming protocols. WPA2-Personal uses a pre-shared key (PSK) to authenticate and encrypt the communication between the VoWiFi device and the access point. WPA2-Enterprise uses 802.1X/EAP to authenticate the VoWiFi device and the RADIUS server, and then derives a unique encryption key for each session. Both WPA2-Personal and WPA2-Enterprise use AES-CCMP as the encryption algorithm, which provides strong security and low overhead. WPA2-Personal and WPA2-Enterprise also support key caching andpre-authentication mechanisms, which reduce the latency and disruption during reassociations. These features are essential for maintaining the quality of service and user experience for VoWiFi communication.
WPA-Personal, WEP, and 802.1X/EAP are not ideal security solutions for protecting VoWiFi communication in an RSN requiring low-latency reassociations and no fast secure roaming protocols. WPA-Personal uses TKIP as the encryption algorithm, which is less secure and more computationally intensive than AES-CCMP.
WPA-Personal also does not support key caching and pre-authentication mechanisms, which increase the latency and disruption during reassociations. WEP is an outdated and insecure encryption algorithm that can be easily cracked by attackers. WEP also does not support any authentication or key management mechanisms, which expose the VoWiFi communication to various attacks. 802.1X/EAP is an authentication framework, not a security solution. 802.1X/EAP alone does not provide any encryption or key management for the VoWiFi communication. 802.1X/EAP must be combined with a robust encryption algorithm, such as AES-CCMP, to provide adequate security for VoWiFi communication.
