Wi-Fi is a wireless networking technology that allows devices to connect to each other over short distances. Wi-Fi has become ubiquitous in recent years, and as such, it has come under attack from hackers. One common way that hackers gain access to networks is by exploiting security vulnerabilities. There are a number of encryption protocols used to protect Wi-Fi networks, and this article will explore which one is used in the wpa2 standard.
WPA-PSK
The protocol used in the WPA standard is called WPA-PSK. This protocol uses a 32-bit key and a 64-bit pre-shared key. The pre-shared key is used to encrypt the data. The key is divided into 8 blocks, and each block is encrypted with a different 8-bit value. The encryption process is described in more detail below.
To create a secure connection, the client must first identify itself to the access point. The client sends its unique identifier, called an ESSID, which is then used to generate an authentication cookie. The access point then encrypts this cookie with the client’s 32-bit key and sends it back to the client. The client uses this authentication cookie to encrypt all traffic that it sends to the access point.
The WPA standard also includes a mechanism called Replay Protection. This mechanism prevents someone from capturing packets that were sent before they were supposed to be sent.
WPA2-AES
The encryption protocol used in the WPA2 standard is WPA2-AES.
WPA2-TKIP
The WPA2-TKIP encryption protocol is used in the wpa standard.
WPA2-CCMP
The WPA2 encryption protocol is used in the wpa standard.
WEP
The WEP encryption protocol is used in the Wi-Fi standard. WEP is a simple encryption protocol that uses a 56-bit key. This key is divided into two parts: the first part is used to encrypt the data, and the second part is used to decrypt it. To create a WEP password, you first need to determine the length of the key. The longer the key, the more difficult it will be to crack. To generate a WEP password, you use a series of random numbers combined with the length of the key.
Conclusion
The WPA2 encryption protocol is used in the 802.11x standard.
