Microwave Access (WiMAX) and Long-Term Evolution (LTE) are considered the best technologies for vehicular networks. WiMAX and LTE are Fourth-Generation (4G) wireless technologies that have well-defined Quality of Service (QoS) and security architectures. Existing work QoS-aware distributed security architecture using the Elliptic Curve Diffie-Hellman (ECDH) protocol that has proven security strength and low overhead for 4G wireless networks. The proposed distributed security architecture using the ECDH key exchange protocol. ECDH can establish a shared secret over an insecure channel at the highest security strength.
