To minimize a security gap in the networks which a single compromised or malicious device can expose an entire mobile network because of the open nature of these networks. The attacker can launch a variety of active and passive attacks. Thus security mechanism is to be defined for call security in 4G/LTE network. The existing scheme includes plain - text certificate key authentication and cryptographic key exchanges. Thus the set of cryptographic key exchange schemes can effectively establish the secure communications between the two node s and protect against the node emulation attacks. In this paper the traditional key exchange models of 4G/LTE network and hybrid cryptographic key exchange model and the security provided by these are evaluated. The proposed model will protect the 4G netwo rk during the initial call setup phase, periodic time based key exchange to ensure the call security and the seed exchange for the other end integrity check. The proposed model will use a pre - shared key group to ensure the security during the call setup ph ase and will use the random table based non - predictive key exchange model for the purpose of in - call security assurance and receiver integrity check by the caller.
