摘要: Dynamic contactless charging is an emerging technology for electric vehicles (EV) on the move. For efficient and proper billing, dynamic requires secure communication between infrastructure EVs that supports very frequent real-time message exchange EV authentication. In this paper we propose Portunes, authentication protocol pads to authenticate EV's identity. Portunes uses pseudonyms provide location privacy, allows roam different sections receive a single bill, achieves fast by relying symmetric keys spatio-temporal of EV. We have implemented RaspberryPi Model B with 700 MHz CPU 512 MB RAM. generate information within 0.3 ms, verify 0.5 ms. comparison, ECDSA signature generation verification take over 25 ms 40 respectively.
