D6.5 Performance Analyses 2

In this deliverable D6.5 “Performance Analyses 2”, we discuss the performance of the two functional encryption libraries developed in FENTEC. We compare both libraries, GoFE and CiFEr, as well as the performance of different schemes between each other.

We summarize the optimizations that have been implemented in the first half of the last year of the project. Additionally, we provide an evaluation of the integration of GoFE into two real-world scenarios and compare the performance of the functional encryption approach against the homomorphic encryption approach. We demonstrate that functional encryption is practical and can be used in real-world applications. This document is an extension of D6.4 “Performance Analyses 1”, where the performance of the initial set of implemented schemes has been discussed.
