issues coming up with the deployment of Wi-‐ Fi (WLAN) networks. The security tools implemented in WiMAX aim to overcome issues like access authorisation‚ user data privacy‚ and privacy key management. Security protocols in WiMAX reside in a MAC sub-‐layer and include authentication protocols (EAP and X.509)‚ key management protocols (PKMv2)‚ and encryption standards (AES and 3DES). The security standard of WiMAX is very high compared to other wireless technologies. However WiMAX is still vulnerable

have access to the building. Keys form the basic foundation for public key infrastructure and it is important that each key be carefully handled. The proper management of keys includes key storage‚ key usage‚ and key-handling procedures. There are different ways to store keys; public keys can be stored by embedding the key within digital certificates‚ while private keys can be stored on a person’s personal computer. However‚ there are drawbacks to storing keys using software; software can leave
