Hole196 is a vulnerability in the WPA2 protocol that abuses the shared Group Temporal Key (GTK). It can be used to conduct man-in-the-middle and denial-of-service attacks. However, it assumes that the attacker is already authenticated against Access Point and thus in possession of the GTK. [51] [52]
The Wi-Fi Alliance refers to their approved, interoperable implementation of the full 802.11i as WPA2, also called RSN (Robust Security Network). 802.11i makes use of the Advanced Encryption Standard (AES) block cipher, whereas WEP and WPA use the RC4 stream cipher.
Temporal Key Integrity Protocol (TKIP / t iː ˈ k ɪ p /) is a security protocol used in the IEEE 802.11 wireless networking standard. TKIP was designed by the IEEE 802.11i task group and the Wi-Fi Alliance as an interim solution to replace WEP without requiring the replacement of legacy hardware.
Due to the limited access of the standard (only eleven Chinese companies had access), it was the focus of a U.S.–China trade dispute. Following this it was submitted to, and rejected by the ISO. It was resubmitted to ISO in 2010, but was cancelled as a project on 21 November 2011 after being withdrawn by China. [1]
Wi-Fi EasyMesh is a certification program based on its Multi-Access Point specification for creating Wi-Fi meshes from products by different vendors, [44] based on IEEE 1905.1. It is intended to address the problem of Wi-Fi systems that need to cover large areas where several routers serve as multiple access points, working together to form a ...
Wireless security is another aspect of computer security. Organizations may be particularly vulnerable to security breaches [6] caused by rogue access points.. If an employee adds a wireless interface to an unsecured port of a system, they may create a breach in network security that would allow access to confidential materials.
The recommended solution to WEP security problems is to switch to WPA2. WPA was an intermediate solution for hardware that could not support WPA2. Both WPA and WPA2 are much more secure than WEP. [21] To add support for WPA or WPA2, some old Wi-Fi access points might need to be replaced or have their firmware upgraded.
In which the user has to bring the new client close to the access point to allow a near-field communication between the devices. NFC Forum–compliant RFID tags can also be used. Support of this mode is optional. USB method In which the user uses a USB flash drive to transfer data between the new client device and the network's access point ...
