Traffic Encryption Key
A traffic encryption key (TEK) is any cryptographic key used specifically to encrypt the data flow (and not for authentication or other purposes). In a WiMAX security association, the base station generates the TEK, encrypts it using the authentication key, and transmits it to the mobile station. The mobile station decrypts the TEK, also using the authentication key. Both stations can then exchange data traffic.
