Physical location based DHCP server design with authentication

Network security has gained more importance with the rapid growth and expansion of the enterprise networks. One of the most important parameters of network security is authentication. In a large-scale network, the user authentication process is a high workload and has some security problems. Managing a user's inclusion process into a network is actually the DHCP (Dynamic Host Configuration Protocol) responsibility as a network protocol. The DHCP supplies facility for the network administrator to manage IP addresses and user to own an IP address. However, due to this protocol without security mechanism, the potential security vulnerabilities such as rogue DHCP server, stolen MAC (Media Access Control) address and DHCP Starvation are getting more important problems. In this study we propose a mechanism for each user that wants to be included in our enterprise network and authenticate oneself without needing to consult with any network administrator. We also propose to fix that user's binding location. So using this information we ensure security and determine IP configuration to clients for next connections. Our goal is to program a new DHCP server that will also use physical information from the network and provide authentication.
