This means that the possibility of reusing the same key during transmission is lesser and consequently it is harder to hack. That is why, changing the key periodically, is important for the security of your wireless network.Ĭompared to WEP, instead of 24-bit initialization keys, WPA uses a 48-bit key, that provides as many as 500 trillion combinations. The fact that master keys are directly used, instead of temporary keys, makes a WEP-secured system, even more vulnerable.

Reused keys or keys that are not changed, make it easier for hackers to crack the code. So, these keys have to be reused after a period of time, which is a major weakness in the WEP encryption strategy. The 24-bit IV key can only have 16.7 million possible combinations. Only the receiving end has the decryption key that converts the data back into original form. So, when anyone intercepts the data, all they see is random nonsensical data, which is unreadable.

Ideally, the IV part has to be different for every packet but the secret key code is fixed. In both these keys, 24 bits are reserved for the ‘Initialization Vector (IV)’.Įvery data packet is encrypted with a combination of IV and a secret key. When it comes to the security of an encryption key, more bits make it stronger.

The encryption keys in WEP consist of 64 bits or 128 bits. Encryption key is present at the wireless network source and decryption key is present at every receiving end. Two complementary keys, that are used, are encryption and decryption keys. Comparison of Encryption Strengthīoth, WEP and WPA2 use secret keys to encrypt data. Let us have a look at the major differences between the two. Still, the standard continues to be used by some manufacturers. When WEP was shown to be vulnerable to hacking, it was replaced by WPA (Wi-Fi Protected Access) and later updated with WPA2 for 802.11i wireless networks. It was developed for the IEEE 802.11 wireless networks. The first wireless network security standard was WEP (Wired Equivalent Privacy), which was designed to provide the same level of security, as a wired network (which explains the name) and it was first released in 1997. Your wireless router is programmed, with such a wireless encryption program, that protects it from unauthorized access. Today, cryptology is an applied field of science, that is devoted to the generation of encryption algorithms to secure data transmission. The receiving end of the data, has the decryption key, using which it decrypts the data. If anybody intercepts the transmission, all he would see is garbled data. Before transmission, data is encrypted (converted into a cryptic form, using certain mathematical algorithms). For secured transmission of data through radio waves, encryption methods were developed. Since the beginning of wireless communication, security of transmitted data has always been a concern. A Comparison Between the Two Encryption Standards Here is a comparison between these two encryption standards, that may help you decide which one to opt for. If all devices are using WPA2 then the best option is to choose WPA2 in the list of wireless security.WPA has been upgraded to WPA2 recently and it is supposed to be a lot more secure than WEP, which is its predecessor. However, if a user is using both TKIP and AES then the network will be left more vulnerable.

This option is provided for compatibility purposes due to some older devices still using WPA. This option means that it will allow both WPA and WPA2 at the same time.

There is also an option for WPA/WPA2 mixer in the security menu for most devices and routers. All of them use different encryption technology and the AES technology of WPA2 is safer. You can find the WPA and WPA2 options available in the list of the wireless security page. Most of the modern modem/router will no longer have an option for WEP since that is the worst protocol for security. However, choosing them as an option in your router or devices is another story. Now that you have the basic knowledge about these three you might already know some differences. WPA2 with AES encryption Difference Between WEP, WPA, and WPA2
