In vehicle-to-grid (V2G) network, electric vehicles (EVs) can store greenpower from renewable energy sources and inject excess power to the grid during the peak hours for monetary benefits. Since transactions are involved in this process, it is pertinent to secure any transmitted packet and protect users’ privacy to ensure fairness in the energy market and combat any privacy issues that can expose the users’ energy profile and hinder the deployment of autonomous vehicle networks (AVNs). In this research article, a lightweight privacy-aware power injection and communication (LPPC) scheme suitable for deployment over vehicular networks and 5G smart grid slice is proposed. In LPPC, each EV prepares its bids and computes two secret keys shared with the utility company and gateway to blind the bids for different time slots. A novel aggregation technique based on elliptic curve cryptography (ECC) is utilized to …
