Searchable Encrypted Mobile Meter
Securing data and ensuring privacy is one of the most difficult challenges as technology becomes increasingly more mobile. Mobile devices allow us the convenience of recording and accessing data from anywhere but, when mismanaged, can be a major source of privacy violation. Furthermore, mobile devices tend to have restraints that limit their computing power which leads to sacrificing security for power. The rest of this paper will focus on securing mobile data as related to Electric Vehicles. Specifically, this paper takes a look at securing a mobile meter that is to be placed in an electric vehicle. This device will use modern encryption techniques while still allowing private queries to the system using Role Based Access Control. This method provides strong security against an adversary who has physical access to the mobile meter as well as allowing multiple users to have access to the same data set while restricting or elevating their privileges. Securing the relatively computationally weak mobile meter in this method also provides the added benefit that most of the computation can be done on a more computationally fit computer. Securing mobile meters in electric vehicles is an area of substantial interest as the amount of information one can potentially gleam from a mobile meter is surprisingly high. This paper also discusses the information that could potentially be gained from an insecure mobile meter.
