For this, a realistic network scenario is deployed to run the simulations and to measure bandwidth, consumption of resources (i.e., CPU cycles and bandwidth usage) and communication latency.

Different ciphering and authentication algorithms are tested, following the recommendations made by the Internet Engineering Task Force (IETF).},
