What is tkip and aes encryption

The key remains the same until it is changed by authorized personnel. You can also configure key change intervals. In this type, every client automatically receives a unique encryption key after securely logging on to the network. This key is automatically updated at regular intervals.

Network Type. You should be using this option. This provides maximum compatibility with any ancient devices you might have, but also ensures an attacker can breach your network by cracking the lowest-common-denominator encryption scheme. Don't be fooled, this is not the standard you want to be using. Using lower standards for compatibility doesn't generally make sense anymore WPA2 certification became available ten years ago! Select that option and then see if anything doesn't work.

If a device does stop working, you can always change it back — although you may just want to buy a new device manufactured at any time in the last eight years rather than compromise your network for the sake of compatibility with an out dated device. Many modern wifi routers that support newest and fastest standards will slow down to 54mbps if you enable WPA or TKIP in their options. So choosing an encryption level isn't just about security.

Hopefully you now have a better understanding of wireless encryption and are ready to update your network so it can be as secure as possible!

Widespread WPA3 won't occur for a little while. Still, you will find routers on the market advertising support for WPA3 when the security protocol rolls out to consumers properly. Here's why. TKIP is essentially a patch for WEP that resolved the problem of attackers uncovering your key after observing a relatively small amount of router traffic.

To address the problem, TKIP fixed this issue by issuing a new key every few minutes, which, in theory, wouldn't give a hacker enough data to break the key or the RC4 stream cipher that the algorithm relies on.

While TKIP offered a significant security upgrade at the time, it has since become a deprecated technology that is no longer considered secure enough to protect your network from hackers. Its biggest but not its only vulnerability is known as the chop-chop attack, which is an attack that predates the release of the encryption method itself. The chop-chop attack allows hackers who know how to intercept and analyze streamed data the network generates to decipher the key and thus display the data in plaintext as opposed to ciphertext.

If you're unsure about the difference between plaintext and ciphertext, check out these basic encryption terms. AES is a totally separate encryption algorithm. It is far superior to any security offered by TKIP. But in addition to this, as we can imagine, it will also pose a problem for performance. It is a fact that the more computers you have connected and using a network, the more problems regarding speed, quality and stability there may be.

If we have intruders in our Wi-Fi it can suppose that the speed drops noticeably. In short, protecting our wireless networks is going to be fundamental and that we must always keep in mind.

That yes, it is necessary to correctly choose the key that we are going to use, as well as the type of encryption within the possibilities that we have at our disposal. It must be said that today they are the safest, since others such as WEP and WPA both in their different variants have become obsolete and there are different tools that allow them to be exploited.

This makes it not recommended to use them at present. Now, within the two types that we can consider safe, they are not equally. It is the most reliable type of encryption. This means that new routers should not use it as it is not considered fully secure today. Therefore whenever possible we should avoid it. Hence, its use is not recommended today if we want to maximize the security of our networks. It is the one that will offer us a greater guarantee and have fewer security problems that can compromise our networks.

Keep in mind that there are also differences in speed. It is another of the factors that we must take into account, beyond the security that is logically the main one. Cisco says that the TKIP encryption is vulnerable to packet decryption by a possible attacker.

But mind you, only the authentication key can be stolen by a hacker. But with the auth key, they can log in to network and then reach devices by using other methods.
