A Secure Wireless Communication System Integrating PRNG and Diffie-Hellman PKDS by Using a Data Connection Core

Abstract

In this paper, we propose a secure authentication scheme, called the Security system with Pseudo random number generator, Diffie-Hellman algorithms and Data Connection Core (SPDiD for short) for a wireless environment. The SPDiD employs a data connection core (DCC for short), as its pre-connected logic link before communication starts, to exchange the keys and messages for a connection authentication, not only reducing the number of steps for the process of authenticating a network entity when comparing it with LTE-A or WiMAX authentication processes, but also generating more symmetry keys by using pseudo random number sequences (PRNSs for short) for key and message encryption without lowering the security level of a wireless session. Moreover, the SPDiD protects the first authentication message delivered between the two network entities at the two ends of a connection by using the DCC of the user, which is only known to the user and authenticator. The purpose is to securely accomplish the mutual authentication between the two network entities, and prevent hackers from capturing the input parameters (i.e., the seeds) of a Pseudo random number generator (PRNG for short). Furthermore, we compare the SPDiD with popular wireless communication schemes, like the LTE-A and WiMAX. The results indicate that the SPDiD has better performance and higher security than the compared systems have.
