Enhancing the Security and Reliability for Data Transmission in Wireless Networks

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.Limitations of high computational and communication overhead in addition to lack of scalability.so that the proposed work propose an unconditionally secure and efficient SAMA. The main idea is that for each message m to be released, the message sender, or the sending node, generates a source anonymous message authenticator for the message m.The generation is based on the MES scheme on elliptic curves. For a ring signature, each ring member is required to compute a forgery signature for all other members in the AS. IMS (IP Multimedia Subsystem) is a set of specifications to offer multimedia services through IP protocol. These make it possible to include all kinds of services, such as voice, multimedia and information, on reachable platform through any Internet link. A multi-attribute stereo model for IMS security analysis based on ITU-T Recommendation X.805 and STRIDE threat model, which provide a comprehensive and systematic standpoint of IMS. Femtocell access points (H(e)NBs) are close-range, limited-capacity base stations that use residential broadband connections to connect to carrier networks. Final conclution to provide hop-by-hop message Authentication without the weakness of the built in threshold of the polynomial-based scheme, then proposed a hop-by-hop message authentication scheme based on the SAMA.
