A DH-DSS Based Approach to Improve Mobile WiMAX Security Against DoS Attack
The convenience of IEEE 802.16-based wireless access networks has led to widespread deployment of this technology. Although IEEE 802.16 has added a security layer, there are some security flaws which lead to some serious threats. Unsecure initial network entry, handover process and sleep mode in IEEE 802.16e based networks can result to DoS attack, which is a great security threat to wireless networks. In this paper, the authors propose a DH-DSS (Diffie Hellman-Digital Signature Scheme) method to provide more security in the initial network entry process.
