Design and Implementation of Ipv6 Address Using Cryptographically Generated Address Method

There is always a tradeoff between privacy and the desired level of security for any internet user in the contemporary cyber world. Cyber security, of late, is paramount and its breach could lead to untoward consequences, at times, disastrous. The advent of the IPv6 provides a hope to resolve this tradeoff satisfactorily. Included in the IPV6 suite is a method for devices to automatically configure their own addresses in a secure manner. This technique is called Cryptographically Generated Addresses (CGAs). CGA provides the ownership proof necessary for an IPv6 address without relying on any trust authority. However, the computation involved in CGAs is very high, especially for a high security level defined by the security parameter (Sec). The sheer cost involved here may pose to be an inhibiting factor for any user to continue with this security regime and may tempt her not to change her address on a frequent basis. Thus, the way forward could be to modify the standard CGA to make it more applicable across applications and scenarios and at the same time not to let it compromise with the optimum security level. We propose to reduce the CGA granularity of the security level from 16 to 8, which make it more feasible for use in most applications and scenarios. And the privacy part is taken care of by changing addresses over time which protects users from being tracked. Here, we strive to implement and evaluate these extensions to the standard CGA.
