Hello
We are commonly using Wifi everyday, anywhere and anytimes safely or not. To avoid as much as possibe some hacker to access to access to our wifi and use them, they are some wireless encryption standards. I am going to summarize them.
Actually we have 4 standards:
Wireless Equivalent Privacy (WEP)
Wep is the original and oldest privacy component of the IEEE 802.11 wireless standard
It was implemented in 19995 an considere compromised and depreciated in 2004
Message sent in clear text
It is susceptible to passive network eavesdropping and replay attacks
Can be cracked in minutes and should never be used
WI-Fi Protected Access (WPA)
WPA was designed as a short-term fix for WEP as long-term, more secure solution (WPA 2) was being created.
Coud be implemented as a firmware upgrade to WEP devices (backwards compatible)
Use encrypted hash
Utilizes TKIP (temporal Key Integrity Protocol) to dynamically change the encryption key
Wi-Fi Protected Access 2 (WPA 2)
Uses AES algorithm for encryption
CCMP replaced TKIP
Wi-Fi Protected Access 3 (WPA 3)
Not yet really used, it has his own approach of security
Thanks
