If you’re using WPA-PSK (Pre-Shared Key), the Linksys WRT54GL gives you two options for WPA Algorithm: TKIP and AES. I knew AES was supposedly the newer and better solution, but I wanted to find out what the main difference between the two was. After searching online for a bit, I found this Wireless FAQ.
19. Q: What is TKIP?
TKIP is a quick-fix method to quickly overcome the inherent weaknesses in WEP security, especially the reuse of encryption keys. TKIP is involved in the IEEE 802.11i WLAN security standard, and the specification might be officially released by early 2003.
20. Q: What is AES?
AES (Advanced Encryption Standard), a chip-based security, has been developed to ensure the highest degree of security and authenticity for digital information, wherever and however communicated or stored, while making more efficient use of hardware and/or software than previous encryption standards. It is also included in IEEE 802.11i standard. Compare with AES, TKIP is a temporary protocol for replacing WEP security until manufacturers implement AES at the hardware level.
