Enable and set the virtual WiFi NIC: run the command: netsh wlan set hostednetwork mode = allow ssid = xiaoyu key = 12345678. This command has three parameters: mode: whether to enable the virtual WiFi Nic, if it is set to disallow, It is disabled.

1. Access WiFi 1.1 wireless peer-to-peer Security WEP (Wired Equivalent Privacy) WEP adopts RC4 symmetric encryption technology at the link layer. The user's encryption key must be the same as the AP's key to allow access to network resources, thus preventing unauthorized user listening and unauthorized user access. WEP provides a 40-bit and 128-bit key mechanism, but it still has many defects. For example, all users in a service area share the same key, if a user loses a key, the entire network

1. WiFi access 1.1 Wireless Peer-to-peer Privacy WEP (Wired equivalent Privacy) WEP uses RC4 symmetric encryption at the link layer, and the user's encryption key must be the same as the AP's key to gain access to the network's resources, thereby preventing unauthorized users from listening and access by illegal users. WEP provides a 40-bit and 128-bit length key mechanism, but it still has many drawbacks, such as sharing the same key for all users in a service area, and a user losing a key wi

WPA2-PSK (AES) of wireless network encryption technology) After the publication of 802.11i, the Wi-Fi Alliance launched WPA2, which supports AES (Advanced Encryption Algorithm).

Alliance launched WPA2, which supports AES (Advanced Encryption Algorithm). Therefore, it requires new hardware support, it uses CCMP (full code protocol for block Chain messages in counter mode ). In WPA/WPA2, PTK generation depends on PMK, and PMK obtains two methods. One is the PSK form, which is the pre-shared key. In this mode, PMK = PSK, in another method,

small and medium-sized enterprise networks or home users, WPA also provides a simplified mode that does not require dedicated Authentication servers. This mode is called "WPA pre-shared key (WPA-PSK)", which requires only one key in advance on each WLAN node (AP, wireless router, Nic, etc.This key is only used for authentication, not for data transmission encryption. The data encryption key is dynamically generated after authentication. The system will ensure "one user and one password". There

WPA2: more powerful wireless encryption technology It may take some time for the full IEEE 802.11i standard to be launched, and the Wi-Fi Alliance wants to enable the new security standard to be deployed as soon as possible to eliminate users'Wireless NetworkSecurity concerns allow the wireless network market to expand quickly. Therefore, the draft of the fifth draft of the IEEE 802.11i (IEEE 802.11i draft 3) of TKIP is developed as a benchmark.WPA. A

environment and in public places. Another way is to keep the key unchanged, which makes the user vulnerable to attacks. Due to interoperability problems, academic environments and public places have never been able to use proprietary security mechanisms. The most powerful wireless encryption technology "WPA2" WPA2 is an IEEE 802.11i standard authentication form verified by the WiFi alliance.

places have been unable to use WEP. The disadvantage of WEP is that its encryption key is a static key and not a dynamic key. This means that in order to update the key, IT personnel must personally access each machine, which is not possible in an academic environment or public place. Another option is to keep the key unchanged, which makes the user vulnerable to attack. Due to interoperability issues, the academic environment and public places have been unable to use proprietary security mecha

, WPA was used to provide users with a temporary solution before the 802.11i protocol was improved. The standard data encryption uses the TKIP protocol (temporary Key Integrity Protocol).
