Wi-Fi Protected Access increases security on two fronts: data encryption and user authentication. To improve data encryption, Wi-Fi Protected Access resolves existing cryptographic weaknesses and introduces a method to generate and distribute encryption keys automatically. Each bit of data is now encrypted with a unique encryption key, greatly improving security. The solution also introduces an integrity check on the data so an attacker cannot modify packets of information being communicated. And to improve enterprise-level user authentication, Wi-Fi Protected Access authenticates every user on the network while keeping those users from joining rogue networks.
