Currently, LTE-A and WiMAX are two of the most popularly studied wireless communication systems. But each of the two systems has its own drawbacks. In LTE-A's authentication mechanism, the dynamic random key RAND when passed to User Equipment (UE) is exposed in the air, thus easily being caught by hackers. Also LTE-A's UE and Home Subscriber Server (HSS) initially are connected by only one key K and one parameter, meaning that its security can be further improved. Whereas the security foundation of WiMAX, i.e., PKMv2, between MN and AAA has its drawbacks and the number of their communication steps can be further reduced. Therefore, in this paper, we propose a secure authentication scheme, called the Security mechanism with a Pseudo Random Number Generator, the Diffie-Hellman algorithm and a Data Connection Core (SPDiD for short), for a wireless environment. The SPDiD employs a data connection core (DCC for short), as its pre-connection logic link before communication starts, a current-time key, as a dynamic parameter, and a Pseudo Random Number Generator (PRNG for short), as its communication key generator, to secure its key and message exchange processes. The DCC is only known to the user (UE or MN) and authenticator (HSS or AAA) of the underlying system to prevent hackers from capturing the seeds of a Pseudo Random Number Generator (shortly PRNG). The analytical results demonstrate that the SPDiD has higher security and better performance than those of the LTE-A and WiMAX.
