ABSTRACT:

Dynamic contactless charging is an emerging technology for charging electric vehicles (EV) on the move. For efficient charging and for proper billing, dynamic charging requires secure communication between the charging infrastructure and the EVs that supports very frequent real-time message exchange for EV authentication. In this seminar, I will discuss Portunes, an authentication protocol for charging pads to authenticate an EV’s identity. Portunes uses pseudonyms to provide location privacy, allows EVs to roam between different charging sections and receive a single bill, and achieves fast authentication by relying on symmetric keys and on the spatio-temporal location of the EV. I will discuss how we have implemented Portunes on Raspberry Pi Model B with 700 MHz CPU and 512 MB RAM and compare it to the use of the Elliptic Curve Digital Signature Algorithm.
