Which mode of key distribution involves preconfigured matching keys on wireless clients and access points?

Pre-shared key (PSK) mode is a method of key distribution that relies on a shared secret, or key, that is manually configured on both the wireless client and the access point prior to establishing a connection. This means that both devices need to have the same preconfigured key, allowing them to authenticate and encrypt communications using that key.

In PSK mode, the key serves as the basis for generating encryption keys that are used to secure the wireless communications between the client and the access point. This approach is often found in smaller networks, such as home networks or small offices, due to its straightforward setup process. While it provides a level of security, the shared key must be carefully managed since if it becomes known to unauthorized users, they can join the network as well.

In contrast, enterprise mode typically involves a more complex key distribution process, often relying on authentication servers (like RADIUS) that manage keys dynamically. Authentication server mode specifically requires an external server for key management rather than relying on preconfigured keys. Dynamic key mode generates keys on-the-fly, enhancing security further by not relying on static shared keys that can be compromised. Thus, in the context of this question, pre-shared key mode is specifically designed around the concept of
