Generation of cryptographic one-to-many mapping IPv6 address using S-AES

The proliferation of enterprise wireless network raises the security concern in any organization despite the unarguable benefits it brings about. At the same time, the initiatives to migrate from IPv4 (Internet Protocol version four) to IPv6 (Internet Protocol version six) is gaining momentum across the globe to resolve the IP address depletion problem as well as reaping the benefit of it. This research proposes a new scheme to manage IPv6 addresses in an enterprise wireless local area network (WLAN) which may be implemented into DHCPv6 (Dynamic Host Configuration Protocol for IPv6) software. Each user will be assigned a group of IP addresses that are generated cryptographically whose parameters as user attributes. Each time user trying to access the network it will be given different IP address which will be generated using S-AES (Simplified Advanced Encryption Standard) algorithm using parameters assigned to that user so that there is a one to many mapping between user and IP addresses. Therefore, the network administrator will be able to identify user realtime from the IPv6 address to facilitate tracking of network anomalies or violation of policies. By the pseudo random IPv6 address generation, we will be able to protect user´s privacy even though the communication is transparent end-to-end.
