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

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
Networks initially adopted the WEP (Wired Equivalent private) security mechanism, but later found that WEP was insecure. 802.11 organizations began to develop new security standards, that is, the later 802.11i protocol. However, it takes a long time for the establishment of standards to the final release, and considering that consumers will not give up their original wireless devices for the sake of network security, before the launch of the Wi-Fi Alliance standard, based on the draft 802.11i,
I write binder and WLAN related topics, which is easier for me. After all, this is what I do. The binder is probably the most complicated thing in Android. In this section, I will talk about some basic concepts first. To lay a foundation for the future. Start with the question.
WLAN includes the following basic concepts:
Wireless Network ProtocolWPA/wpa2WLAN and WiFi
I personally think that before learning WLAN, you need to understand some basic wireless network protocols and the differences bet

To compare with enabling WEP encryption, we will introduce how to enable WPA encryption in another example. Enabling WPA encryption is similar to enabling WEP encrypt
transmission power. The reason why many wireless signals can be found, even networks within one kilometer, it is related to its signal transmission power. using it for a long time will cause a considerable amount of radiation to the body. A high power directly means a great harm to the human body. Therefore, for your own security, "strong search antenna" is still useless. Of course, if you have to use this type of equipment, please be careful not to alert the other party, do not use BT to downl
pay great attention to the security of your network, do not use WEP as much as possible in the future, because it is really not very secure.

Installing a wireless network can be confusing for someone like you who has no previous networking experience. So why don't you try to install security? Research has shown that despite potential identity theft and credit card fraud warnings, 75-80% 's home network users are ignoring the configuration of WPA (Wi-Fi Protected Access) security. Now, Secureeasysetup (SES) makes it easy to set up a wireless network and install
. Click the basic settings, first turn on the security settings, and select WEP on a line labeled security type.
Select 16 in the key format, enter the key, and click Save. Write down this key. After you click Save Settings, any computer that was previously connected to the wireless router will lose its connection. This is normal because you have modified the way they communicate with the wireless router, but you haven't told them what security keys to use to access the wireless router.

The returned ilist is actually an object [] []. Obviously it does not meet our requirements. What we need is a set object.
So how can we convert the returned two-dimensional array to our object set? Come with me ....
