â€¢WPA was designed in 2003 as a replacement for WEP and was quickly followed in 2004 by WPA2, the algorithm that remains the standard today
â€¢Non-static encryption key
â€¢WPA uses a hierarchy of keys: New keys are generated for confidentiality and integrity of each session, and the encryption key is automatically changed on each packet
â€¢This way, the keys that are most important are used in very few places and indirect ways, protecting them from disclosure
â€¢WPA allows authentication by password, token, or certificate
â€¢WPA adds support for AES (advanced encryption standard), a much more reliably strong encryption algorithm
â€¢WPA includes a 64-bit cryptographic integrity check
â€¢WPA sessions begin with authentication and a four-way handshake that results in separate keys for encryption and integrity on both ends
â€¢While there are some attacks against WPA, they are either of very limited effectiveness or require weak passwords â€“ long random passphrase is best
