What method involves using the same password on both the wireless access point and client device for encryption?

The method that involves using the same password on both the wireless access point and the client device for encryption is known as a Pre-Shared Key (PSK). This approach is commonly used in wireless networks, particularly in WPA (Wi-Fi Protected Access) and WPA2 security protocols.

When setting up a wireless network in PSK mode, the user creates a shared password that must be entered on both the access point and any devices that will connect to the network. This shared password is then used to generate encryption keys that protect the data transmitted over the network. The simplicity of using a Pre-Shared Key makes it easy to set up and is suitable for home and small office networks where complex authentication methods are not necessary.

On the other hand, Temporal Key Integrity Protocol (TKIP) is an encryption protocol that was used with WPA but does not specifically refer to the sharing of a password between devices. Multi-User MIMO (MU-MIMO) is a technology that allows multiple devices to communicate with a single router simultaneously, enhancing network efficiency but does not relate to encryption directly. The Advanced Encryption Standard (AES) is a symmetric encryption standard used for securing data, but it does not specify the use of shared passwords in the manner that PSK does
