New accepted paper at IEEE International Performance, Computing and Communications Conference (IPCCC) [19.08.21]
Christian Krupitzer from the Department of Food Informatics is co-author of the peer-reviewed conference paper "Benchmarking of Pre- and Post-Quantum Group Encryption Schemes with Focus on IoT" at the IEEE International Performance, Computing and Communications Conference (IPCCC; CORE Rating: B).
The publication of Thomas Prantl (University of Würzburg) with co-authors Dominik Prantl, André Bauer, Lukas Iffländer, Alexandra Dmitrenko, Samuel Kounev (all University of Würzburg) and Christian Krupitzer (Department of Food Informatics, University of Hohenheim) was accepted at the International Performance, Computing and Communications Conference (CORE Rating: B; peer-reviewed). The International Performance, Computing, and Communications Conference, sponsored by IEEE, is a conference to present research in the performance of computer and communication systems.
In the next few years, both the number of IoT devices and the performance of quantum computers will increase. Both technologies pose a challenge to our current cryptostrategies. Therefore, post-quantum n-to-n communication encryption is a crucial field of research. Here, the development of new schemes and the analysis, and comparison of existing schemes is necessary. However, current work only investigates the performance of post-quantum schemes only for 1-to-1 communication. Therefore, in this paper, we analyze existing post-quantum schemes concerning n-to-n communication and compare them with pre-quantum schemes. Our results show that the pre-quantum schemes perform better regarding computation times than the post-quantum schemes, but the differences are sometimes only marginal. However, these marginal differences in computation times lead to the lower energy efficiency of the post-quantum schemes. In terms of features, there is no difference between both scheme classes. We show that the post-quantum schemes require unicast, whereas some pre-quantum schemes also support broadcast. Deciding whether to use pre- or post-quantum schemes for n-to-n encryption in IoT use cases depends on (i) whether energy efficiency is essential – e.g., in case of limited power supply – and (ii) whether unicast or broadcast is available.
