In cryptography, a pre-shared key (PSK) is a shared secret which was previously shared between the two parties using some secure channel before it needs to be used. [ 1 ] Key
TLS-PSK uses symmetric keys, shared in advance among the communicating parties, to establish a TLS connection. There are several reasons to use PSKs: Using pre-shared keys can, depending on the ciphersuite, avoid the need for public key operations. This is useful if TLS is used in performance-constrained environments with limited CPU power.
After the PSK or 802.1X authentication, a shared secret key is generated, called the Pairwise Master Key (PMK). In PSK authentication, the PMK is actually the PSK, [6] which is typically derived from the WiFi password by putting it through a key derivation function that uses SHA-1 as the cryptographic hash function.

PRIVATE WiFi assigns you an anonymous, untraceable IP address that hides your actual IP address and location; PRIVATE WiFi solves the inherent security problems of public WiFi hotspots by giving you the same encryption technology used by corporations, big banks, and the government; PRIVATE WIFI also works for wired internet connections
PRIVATE WiFi will automatically activate and connect to an encrypted server whenever you access the internet. If you change this default setting, you can activate PRIVATE WiFi at any time clicking on the status icon ( PC: right-click the icon in the Taskbar at the bottom right of your screen, Mac: click the Menu Bar icon at the top right of ...
These include design flaws in the Wi-Fi standard, affecting most devices, and programming errors in Wi-Fi products, making almost all Wi-Fi products vulnerable. The vulnerabilities impact all Wi-Fi security protocols, including WPA3 and WEP. Exploiting these flaws is complex but programming errors in Wi-Fi products are easier to exploit.
Some devices with dual-band wireless network connectivity do not allow the user to select the 2.4 GHz or 5 GHz band (or even a particular radio or SSID) when using Wi-Fi Protected Setup, unless the wireless access point has separate WPS button for each band or radio; however, a number of later wireless routers with multiple frequency bands and ...
The iPhone doesn’t have a privacy mode, as Android phones do, but there are Apple privacy settings users can enable to reduce the likelihood their personal information will be compromised.
