How-To Geek is where you turn when you want experts to explain technology.

The WPA standard allows users to connect wirelessly to a network using any compatible device and is one of the most widely used wireless security methods.

WPA Wi-Fi Security was introduced in and is now the most popular type of wireless network security. It uses a passphrase that is used to create a shared key between the wireless router and your device.

It presents various encryption options according to the type of your WiFi router. But the most popular ones among them is WPA2-Personal, since it has been used by millions of devices at homes or small businesses. With this method, all users of the wireless network share the same key and thus, be vulnerable to attacks. It used a secret password to encrypt, but once it is cracked, all data and network packets could be monitored.

Now this was more secure, but still vulnerable. We have WPA3 now, which is currently seen as the most secure option. The main difference between WPA and WEP is that the former uses a four-way handshake while the latter uses a two-way handshake.

This means that with WPA, each party must agree to a key before the connection can take place, while with WPA2, each party must be authenticated before the connection can take place.

It was designed to ensure the confidentiality of Wi-Fi traffic and to protect against network attacks. AES is a symmetric block cipher that was released in AES Advanced Encryption Standard is a set of ciphers that is available in a block size of bits and key lengths of , or bits, depending on the hardware.

In contrast to its predecessor, AES does not use the Fiestel network and instead uses a design principle called the substitution permutation network as the basis for the block cipher algorithm. While some cryptographers occasionally provided evidence of alleged vulnerabilities in AES, all of them proved impractical or ineffective against a full AES implementation. This makes it impossible to brute force the key.

The security level between these two is that the encryption algorithm used by AES can be brute forced if the key size is not bits.

The main benefit of using these protocols is that they are more secure than WEP and have a better range. One of the biggest advantages is that it makes it easier to implement security in a large-scale setting. In addition, it offers features that make it easier to implement authentication and encryption of data on the WiFi network. Modern routers and AES is a more secure encryption algorithm, but it takes longer to encrypt and decrypt files.

However, there have been vulnerabilities in the TKIP protocol that make it less secure. First of all we want to remember the importance of correctly protecting our wireless networks. There are many types of attacks that intruders can use to break our security. 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.

A good passphrase can mitigate the potential risk associated with using an SSID as a seed. A passphrase should be generated randomly and changed often, particularly after using a wifi hotspot and when an employee leaves a company. You can treat this as the same thing.

He also provides the below tips:. This means more powerful hardware is needed to avoid lower network performance. This issue concerns older access points that were implemented before WPA2 and only support WPA2 via a firmware upgrade.

Most of the current access points have been supplied with more capable hardware. The rollout is expected to take some time possibly to as late as while vendors certify and ship new devices.

For a start, you should ensure you select the most secure encryption method. You got it; in the end, it is likely you will have to buy a new router.
