Dynamic key generation is a security feature used in wireless networks to provide each user with a unique encryption key, which is dynamically generated and distributed by the authentication server. This method enhances security by ensuring that even if one key is compromised, it does not affect the security of other users' connections. The correct command to configure an access point (AP) to require wireless users to authenticate using dynamic key generation is AP(config-if-ssid)# authentication dynamic open wep_dynamic.
This command sets the AP to use dynamic WEP (Wired Equivalent Privacy) keys along with open authentication.
