Wireless 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 rel
Two common encryption methods: WEP and WPA
Currently,WirelessThere are already several encryption technologies in the network. WEP and WPA are the most common encryption methods. 802.11 Wired Equivalent Privacy (WEP), the first security protocol for a wireless LAN, has been questioned. Although WEP can prevent hackers from entering the wireless network, there is still reason to doubt its security, because W

Wired Equivalent security mode was found to have serious disadvantages. However, the 1990s error should not be caused by wireless network security or IEEE 802.11 standard. The wireless network industry cannot wait for the association of Electrical and Electronics Engineers to revise the standard, therefore, they launched the temporary Key Integrity Protocol TKIP (Dynamic Wired Equivalent confidential patch version ).Although WEP has been proven to be outdated and inefficient, it is still suppor

Turn on wireless network encryption so that even if the data you transmit on the wireless network is intercepted, there is no way (or is not so easy) to read. Two commonly used encryption WEP, WPA Currently, several encryption technologies exist in wireless networks, most commonly using WEP and WPA two encryption methods. The first security
Wireless network technology is growing, but how can we use encryption protocols to ensure the security of wireless networks? This shows us how to set security.
With the increasing maturity of wireless communication technology, the price of wireless communication products is falling, and wireless LAN is gradually entering thousands of households. However, wireless network security issues are also worrying. After all, some "unexpected" people have the opportunity to access and even peek, tamper wi
With the maturity of network technology, network security has become the focus of all people. So what should we pay attention? Here we will introduce WPA and other technical aspects. The security of wireless networks has become a topic that cannot be ignored. We will discuss in detail the details of WPA, especially for home and small enterprise users. Next we will introduce the wireless setting wizard for W

Then, EMS is like high-level wireless network encryption mode, it can greatly protect the security of wireless network information transmission.
Wireless encryption options in wireless routers
Currently, the wireless router has the following encryption modes: WEP, WPA
What is a contract?
Let's take a look at a very simple example:
Void Wordlist.insert (string word)
This function is responsible for inserting word in ascending order into the list of words in wordlist, which Word cannot assume null.
The above descriptive text is used to describe the behavior of this function. When the caller who uses the function sees these descriptive text, you know how the function should be invoked and the function behavior in dif

JADT Data structure
JADT includes a variety of components and services, depending on the characteristics of the JADT or specific subset used. The first stop of your JADT journey is a set of classes and interfaces that provide a general method of data organization. Because all services use these data structures, it is important for JADT users to understand them.

Understanding mainstream wireless encryption methodsFirst, let's take a look at the mainstream wireless encryption methods, that is, the WEP, WPA, and WPA2 encryption methods that often appear in the security settings of wireless routers. WEP (Wired Equivalent Privacy, Equivalent Wired confidentiality ). According to the name, WEP seems to be a secure encryption protocol for wired networks, but this is not the case. The WEP standard was created in the
network, the wireless workstation around the local wireless network may intercept data files that do not adopt encryption protection measures, and the data files sent locally will leak the privacy information; if we do not want these data files to leak external privacy information, we should encrypt them or take other security measures before transmitting the target data files, ensure that workstation users who do not know the decryption method cannot access the specific data content.
Currently
With the development of wireless technology, more and more people began to use wireless internet, install a wireless router or AP, you can freely mobile internet, free from the constraints of the cable. But when you rub off the net, do you still feel like you have a wireless network that you can only enjoy on a secure scale? The answer may be negative.
In general, our wireless router or AP now supports WEP/WPA/WPA2 three encryption methods, if you
Wireless routers offer three types of wireless security: WPA-PSK/WPA2-PSK, WPA/WPA2, and WEP. Security settings are different under different security types.
1. Wpa-psk/wpa2-psk
WPA-PSK/WPA2-PSK security type is actually a simplified version of WPA/WPA2, which is based on
