Due to sparse charging infrastructure and short driving ranges, drivers of battery electric vehicles (BEVs) can experience range anxiety, which is the fear of stranding with an empty battery. To help eliminate range anxiety and make BEVs more attractive for customers, accurate range estimation methods need to be developed. In recent years, many publications have suggested machine learning algorithms as a fitting method to achieve accurate range estimations. However, these algorithms use a large amount of data and have high computational requirements. A traditional placement of the software within a vehicle's electronic control unit could lead to high latencies and thus detrimental to user experience. But since modern vehicles are connected to a backend, where software modules can be implemented, high latencies can be prevented with intelligent distribution of the algorithm parts. On the other hand, communication between vehicle and backend can be slow or expensive. In this article, an intelligent deployment of a range estimation software based on ML is analyzed. We model hardware and software to enable performance evaluation in early stages of the development process. Based on simulations, different system architectures and module placements are then analyzed in terms of latency, network usage, energy usage, and cost. We show that a distributed system with cloud-based module placement reduces the end-to-end latency significantly, when compared with a traditional vehicle-based placement. Furthermore, we show that network usage is significantly reduced. This intelligent system enables the application of complex, but accurate range estimation with low latencies, resulting in an improved user experience, which enhances the practicality and acceptance of BEVs.

“…Concrete parameters for the DLP-IBE scheme were proposed in [9], [10], [11] for 80-bit and 192-bit security. In this work, we target 128-bit security level, where n = 1024 and q ≈ 2 23 , as recommended in [9] and [10]. To ensure that prime q allows efficient modular multiplication, we choose q = 8380417 = 2 23 − 2 13 + 1 which supports fast Barrett reduction due to its special structure [14].…”

Identity-Based Encryption (IBE) is considered an alternative to traditional certificate-based public key cryptography to reduce communication overheads in wireless sensor networks. In this work, we build on the well-known latticebased DLP-IBE scheme to construct an ID-based certificateless authenticated key exchange for post-quantum Transport Layer Security (TLS) handshakes. We also propose concrete parameters for the underlying lattice computations and provide detailed implementation results. Finally, we compare the combined computation and communication cost of our ID-based certificate-less handshake with the traditional certificate-based handshake, both using lattice-based algorithms at similar postquantum security levels, and show that our ID-based handshake is 3.7× more energy-efficient, thus highlighting the advantage of ID-based key exchange for post-quantum TLS.

“…However, TLS requires public key transmission and verification between clients and servers, resulting in long handshake latency. Although some researchers proposed to incorporate IDbased cryptography (IBC) into the hand-shake protocol to shorten handshake duration [8], such a protocol suffers from high computational and communication costs, which cannot be applied directly to space information networks. In [9], the authors proposed a TCP header compression method to reduce the header overhead and improve the performance of satellite-based virtual private networks (VPNs), while at the same time guaranteeing a given encryption performance.…”
