Wireless mobile WIMAX Project

WiMAX, meaning Worldwide Interoperability for Microwave Access, is a telecommunications technology that provides for the wireless transmission of data using a variety of transmission modes, from point-to-point links to full mobile cellular-type access. The technology provides up to 70 Mb/sec symmetric broadband speed without the need for cables. The technology is based on the IEEE 802.16 standard (also called Wireless MAN). The name "WiMAX" was created by the WiMAX Forum, which was formed in June 2001 to promote conformity and interoperability of the standard. The forum describes WiMAX as "a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL"[1] (and also to High Speed Packet Access)
Our project based on Mobile WiMAX secure Authentication and Authorization of MS from ASN. Our work can be divided into three main entities: Mobile station, ASN and CSN. When we entered into the Mobile WiMAX network then after scanning the frequencies Mobile station synchronize the up link frequency and then obtain CID of the BTS. Then Mobile Station send authentication and authorization request to the ASN. In ASN there is AAA proxy client which route the subscriber request to AAA server in CSN. In AAA server validate the user by checking subscriber’s digital certificate (X.509) with the help of policy function database. If the user is authenticated then it will be generated an encrypted master key by evaluating the crypto system followed by the MS. Then update the subscriber’s profile and then send to the AAA client then AAA client create a service flow authorization and then send ACK to Mobile Station. Then MS decrypt the encrypted master key with its private key.
