Table 31-9 Configuration items of security configuration of crypto type wireless service
Item Description
Authentication Type
Authentication method, which can be:
Open-System: Namely, no authentication. With this authentication mode
enabled, all the clients will pass the authentication.
Shared-Key: The two parties need to have the same shared key configured for
this authentication mode. You can select this option only when WEP encryption
mode is used.
Open-System and Shared-Key: It indicates that you can select both
open-system and shared-key authentication.
WEP encryption can be used together with open system and shared-key
authentication.
Open system authentication: When this authentication mode is used, a WEP
key is used for encryption only. If the two parities do not use the same key, a
wireless link can still be established, but all data will be discarded.
Shared-key authentication: When this authentication mode is used, a WEP key
is used for both authentication and encryption. If the two parties do not use the
same key, the client cannot pass the authentication, and thus cannot access
the wireless network.
Cipher Suite
Encryption mechanisms supported by the wireless service, including:
CCMP: Encryption mechanism based on the AES encryption algorithm.
TKIP: Encryption mechanism based on the RC4 algorithm and dynamic key
management.
CCMP and TKIP: It indicates that you can select both CCMP and TKIP
encryption.
Security IE
Wireless service type (IE information carried in the beacon or probe response
frame):
WPA: Wi-Fi Protected Access
RSN: An RSN is a security network that allows only the creation of robust
security network associations (RSNAs). It provides greater protection than
WEP and WPA.
WPA and RSN: It indicates that you can select both WPA and RSN.
