Background technique

With the development of dark hacking technology, wifi (Wireless-Fidelity, wireless network) has been exposed to have major security loopholes. The vulnerability is called KRACK (Key Reinstallation, key reinstallation attack), which involves a very wide range and affects almost all wifi devices such as computers, mobile phones, and routers, allowing hackers to monitor data communications through network devices connected to wifi. Steal user privacy, and can hijack the user client to a phishing hotspot to realize traffic hijacking, tampering, etc. It is based on the WPA2 (wifi Protected Access2, wifi protected access second edition) confidentiality protocol, the attacker will reuse the one-time key provided by the client device when it joins the wifi network, and use this method to crack the access point and client device information exchanged between. This has the potential to expose credit cards, chat messages, and passwords. The essence of this vulnerability is to use a shared key to access the network, especially in public wifi, the shared key is known to all the public, so that wireless eavesdroppers can decrypt even encrypted wireless signals.

At present, almost every terminal has its own wifi, or other wifi that can be connected to such as home or work. However, when the terminal moves to a place where the home wifi cannot cover, the wifi service cannot be obtained. Even if you can search a lot of wifi information, because you don't have access authorization, your own wifi may be idle at this time. Whether it is possible to use wifi in a more fair way, so that the terminal's own wifi can provide external services, and at the same time, when the terminal is out of town, it can be safely connected to other people's wifi to improve communication efficiency. The problem.
