Intel patents a new way to connect Wi-Fi devices to wireless networks
Wanting to further simplify the lives of users who are actively using wireless networks, Intel has patented a new way to connect a Wi-Fi device to the router without entering passwords and is suitable, mainly for home use. True, there is some caveat - and the connected device and the router - must have audio capabilities.
The essence of the proposal is as follows: for the first time a device connected to a wireless network must generate some unique — within a given network — sequence of sounds that the router recognizes, and the new device is stored in its database as legitimate. In the future, the user will simply need to repeat the same procedure without having to enter passwords or any PIN codes. The authors of the patent are quite aware that this is not about laptops or smartphones that are fully capable of connecting to the network as many times as possible, having passed the authentication procedure once: this is primarily about connecting to a wireless network of TVs, wireless speakers and (or) headphones, when on the router you need to enter the 8-digital PIN-code of the device, recorded somewhere on its back wall.
The technology described in this US 2011/0277023 patent is positioned as a potential replacement for the Wi-Fi Protected Setup (WPS) protocol, which allows the user to easily connect to wireless networks by entering short PIN codes. It should be recalled that quite recently a dangerous vulnerability was discovered in WPS, allowing a hacker to gain access to the network in a reasonable time using the “brute force” method.
