Wpa2 is more secure than its predecessor, wpa wifi protected access, and should be used whenever possible. Wpa or wifi protected access due to wep security flaws, wpa was the next encryption software to be introduced. Differences among wep, wpa and wpa2 wireless security.

The first iteration of the wpa protocol used the same cipher rc4 as wep but added tkip termporal key integrity protocol to make it harder to decipher the key. In addition to preventing uninvited guests from connecting to your wireless network, wireless security protocols encrypt your private data as it is being transmitted over the airwaves. The most common wpa configuration is wpapsk preshared key. Eap implementation should not be in an effort to increase the cryptographic strength of a wireless network but to. On wifi networks there can be a tradeoff between good security and good audio. Most manufacturers have turned off the option for wep, or at the least disabled the automatic configuration. The isuoitwpa implementation supports either wpa with tkip or wpa2 with aes. Wpa on the other hand is short for wifi protected access.

Pdf comparative analysis of wireless security protocols. Wpa2 wifi routers support a variety of security protocols to secure wireless networks. Wpa2 has stronger security and is easier to configure than the prior options. Wep vs wpa vs wpa2 difference between wep,wpa,wpa2. In terms of security, aes is much more secure than tkip. This made wpa2 a better and more secure configuration compared with wpa. There are several configurations such as enterprise and personal configurations.

However wpa2 is recommended over its predecessor wpa wifi protected access. It took longer than expected to complete the standard, so wpa was created based on a draft of 802. Wpa and wpa2 are two different protocols for wifi connection and security. Wifi protected access, or wpa,uses the temporal key integrity protocol, or tkip,to add security that wep didnt have. The keys used by wpa are 256bit, a significant increase over the 64bit and 128bit keys used in the wep system. Wifi protected access 2 wpa2 a year later, in 2004, wifi protected access 2 became available. In wpa, aes was optional, but in wpa2, aes is mandatory and tkip is optional. These wireless security protocols include wep, wpa, and wpa2, each with their own strengths and weaknesses. Network security protocols are defined and examined here. Second, using a technology known as wired equivalent privacyor wep, uses very weak encryption that is easy to hack. A survey on wireless security protocol wpa2 csce20 online. You need to ensure that if users of your free wifi service do something illegal, you can provide the authorities with information that allows identifying the offender.

Wpa2 psk, provided the shared password is of sufficient complexity, is unbreakable given current resources. It works by having the access point connect to a database first when a user tries to connect to the network, and checks to see if the credentials are valid every time. The wpa2 standard has two components, encryption and authentication which are crucial to a secure wireless. The passphrase for both wpa and wpa2 clients remains the same, the access point just advertises the different encryption cyphers available to be selected for use by the client. Temporal key integrity protocol and advanced encryption standard. Wpa preshared key is static and it is used in initiating communication between two users. This is just a basic outline of the wpa versus wpa2. In particular, it includes mandatory support for ccmp, an aesbased encryption mode.
