Read through to learn about the history of how these security protocols evolved.

It was the standard protocol from to While this version was made to protect, it had poor security and was hard to configure. Cryptographic technology imports were restricted at the time, meaning that more manufacturers could only use bit encryption. This is a very low bit encryption compared to the bit or bit options available today. Ultimately, WEP was abandoned for a more advanced solution. If you have a system with WEP, it should be upgraded or replaced.

This temporary enhancement still has relatively poor security but is easier to configure. As the WiFi Alliance made this transition to a more advanced protocol, they had to keep some of the same elements of WEP so older devices would still be compatible. Unfortunately, this means vulnerabilities, such as the WiFi Protected Setup feature which can be hacked relatively easily , are still present in the updated version of WPA.

A year later, in , WiFi Protected Access 2 became available. WPA2 has stronger security and is easier to configure than the prior options.

The only notable vulnerability of WPA2 is that once someone has access to the network, they can attack other devices connected to the network. The lattermost reason was enough for vendors and business managers to embrace it enthusiastically. How vulnerable is TKIP really? However, only the authentication key can be stolen by an attacker, not the encryption key.

The attacker can only decrypt one packet at a time, currently at a rate of one packet per minutes. Additionally, packets can only be decrypted when sent from the wireless access point AP to the client unidirectional.

The problem is, if the white hats are discovering discover larger vectors for inserting attacks , so are the black hats. It converts plaintext into ciphertext and comes in key lengths of 28, , or bits.

The longer the key-length, the more inscrutable the encrypted data by hackers. Security experts generally agree AES has no significant weaknesses. AES has only been successfully attacked a few times by researchers, and these attacks were mainly side-channel ones.

For well-explained technical details about how AES works, which is out of the scope of this article, visit eTutorials. Although WPA2 is a certification program, it is often referred to as a standard and sometimes as a protocol. We can use the analogy of a vehicle being certified as roadworthy.

The manufacturer will have guidelines that specify safety standards. When you buy the car, it will have been certified as safe to drive by an organization that specifies the standards for vehicle safety. So, while WPA2 should be called a certification, it could loosely be called a standard. And, according to a Stack Exchange user, TKIP is not actually an encryption algorithm ; it is used to ensure data packets are sent with unique encryption keys.

He is correct in that EAP specifies the way messages are transmitted; it does not itself encrypt them. We will touch on this again in the next section. WPA2, and other wifi certifications, use encryption protocols to secure wifi data. WPA2-Personal supports multiple encryption types. A cipher is simply an algorithm that specifies how an encryption process is performed. According to AirHeads Community :. You can see vendors are mixing a cipher with a encryption protocol.

It was designed primarily for general home and office use. PSK does not need an authentication server to be set up. Users log in with the pre-shared key rather than with a username and password as with the Enterprise edition. Later versions were often developed to improve the speed of data transmits and catch up with new security technologies. The latest WPA2- Enterprise versions conforms with Its underlying authentication protocol is EAP is the standard used to transmit messages, and authenticate client and server authenticator before delivery.

The PMK is based on a known value the passphrase , so anyone with that value including an employee who leaves the company could capture the key and potentially use brute force to decrypt traffic.
