This piece briefly touches on WPA2, the latest Wi-Fi security mechanism, but also looks at what some say are shortcomings in security provisions built into WiMax: Some vendors are saying that the authentication scheme built into the WiMax standard is weak. They also say that DES 3, the encryption method supported by the standard is weaker than AES, another encryption method which is supported in WPA2. Apparently Intel has submitted a proposal for including AES in WiMax. It also sounds like some vendors may hope to support strong security mechanisms as a way to differentiate their products and attract security-conscious customers.
