HIP

Experimenting with Python implementation of Host Identity Protocol

Host Identity Protocol, or HIP, is a layer 3.5 solution and was initially designed to split the dual role of the IP address - locator and identifier. Using HIP protocol one can solve not only mobility problems but also establish authenticated secure channels between two communicating end-hosts. In this short article, we first introduce relevant background information. We then present some mathematical background related to Elliptic Curve (EC) Cryptography and Diffie-Hellman protocol based on EC. Finally, we demonstrate some micro benchmarking results for various cryptographic primitives and conclude the paper with the results for the overall performance of HIP and IPSec, which we implemented in Linux user space using Python language.
