TKIP and AES are two encryption methods that can be chosen under WPA or WPA2 wireless security options during the setup of a wireless network. AES, or Advanced Encryption Standard, uses stronger technology for encryption, but not all devices support it. TKIP, or Temporal Key Integrity Protocol, uses less-secure encryption technology and has wider adoption by devices on the market, as of 2014.
TKIP as a security encryption protocol was developed along the same design as the WEP, and it is, therefore, a more vulnerable security option. However, TKIP improves upon WEP's static encryption key, as it utilizes a per-packet key, which generates unique keys for each packet sent. TKIP can be compromised by a keystream recovery attack, where hackers are able to guess individual bytes inside a data packet, which the system confirms or denies.
AES is built on a more secure base and was adopted as the security standard of the U.S. government in 2002. This encryption system was designed by the Dutch designers Vincent Rijmen and Joan Daemen. AES was designed with low computer specifications and has been noted to perform well on a variety of hardware. Although several groups have attempted to compromise the AES system, as of 2014, none have proven successful.
