Key Management in WiMax

In Worldwide Interoperability for Microwave Access (WiMAX) host mobility and secure communication is a big challenge due to the unreliable nature of wireless communication. Usually, cryptographic techniques are used for secure communication in networks, it may be wired and wireless. Cryptographic techniques are ineffective if its key management is weak in wireless networks. So, the key management is also a fundamental and challenging issue in securing WiMAX. In this paper, we have addressed key management issue that allows users to generate public keys to achieve authentication, integrity and confidentiality in WiMAX. Furthermore, we have also evaluated key management using RSA(Rivest-Shamir-Adleman) on different key sizes over WiMAX.
