Enactment Assessment in 4G Networks using Sheltered Asymmetric Key Interchange Method

Abstract

Often in wireless communications the cryptographic algorithm is considered as ‘the security solution’ but actually it is only the nucleus. The means for using the cryptographic algorithm is the ‘key’ used by the algorithm. The existing schemes includes both plain-text and cryptographic key exchanges. The cryptographic key exchange schemes can effectively establish the secure communications between the two nodes 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 network 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 phase 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. This performance evaluation survey will evaluate these two authentication methods for various scenarios in the 4G network. The conclusion after the comparison would throw light on appropriate scenarios of both the schemes used in 4G/LTE security.
