A system for providing security in a mobile Microwave Access (WiMAX) network system is constructed with a licensed certification authority providing a certificate and a first encryption module storing the certificate provided by the licensed certification authority, encrypting a traffic encryption key and a message generated by the first encryption module with the stored certificate, and transmitting the encrypted traffic encryption key and message to a destination. When receiving a message encrypted with a traffic encryption key, the first encryption module decrypts the received message with the traffic encryption key generated by the first encryption module and processes the message. The system is further constructed with a second encryption module. When receiving the message encrypted with the certificate from the first encryption module, the second encryption module decrypts the received message with the certificate provided by the licensed certification authority to detect the traffic encryption key, and encrypts a message with the detected traffic encryption key to transmit the encrypted message.
