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. The algorithm is a bit, bit, or bit block cipher that doesn't feature any of the same vulnerabilities that TKIP had. To explain the algorithm in simple terms, it takes plaintext, and converts it to ciphertext. Ciphertext looks like a random string of characters to an observer that doesn't have the encryption key. However, there is speculation, partially based on Edward Snowden's leaked National Security Agency NSA documents, that AES does have at least one weakness: a backdoor that might have been purposely built into its design.
Theoretically, a backdoor would allow the U. With AES encryption serving as the backbone of WPA2 security and many other security measures for the internet, the potential existence of a backdoor is cause for great concern. Security measures can reduce the data speeds, or throughput, you are able to achieve in your local network.
However, the security protocol you choose can dramatically change your experience. The video below is of a series of performance tests that showcase the different throughput each security protocol can achieve.
The video below describes the more technical differences between these two modes. The following video briefly explains how to select a security protocol in a Linksys router's settings. This video explains how to create a strong password that is easy to remember.
