FADEC: Fast authentication for dynamic electric vehicle charging

In this paper we have presented FADEC, authentication for dynamic electric vehicle charging. FADEC lets EVs establish symmetric keys with the RSUs and the utility company, and achieves fast signing, fast verification, fast hand-off authentication, and low communication overhead. Our simulations have shown that FADEC obtains very close to 1 report delivery ratio and small delay in both resource rich and constrained scenarios. Compared with ECDSA, FADEC reduces the data delivery delay by at most 97% and improves the delivery ratio by more than an order of magnitude. In the future we will perform a thorough security analysis of FADEC, as well as evaluate its performance under more complex traffic scenarios.
