The paper talks about securing software in electric vehicles (EV). With the advancement in the over the air (OTA) technology, there has been increase in potential threats as well. OTA helps the OEMs to update the software in lesser cost and lesser time. However, as it is wireless communication, it is prone to security attacks. OTA consists of several steps and each step is prone to different security attack. The possible security attack area lines are pointed out and discussed in this paper and validated proposed results. The probable threats that can happen during data transfer from cloud to the vehicle main unit (VMU) and VMU to sub units such as but not limited to traction controller. This paper proposes a new type of cipher. It has several benefits that are not limited to confidentiality. Its nature allows calculations to be performed directly on translated data without the need for decryption as opposed to conventional ways. The proposed system helps in reducing the time to market further and provides extra layer of security. It helps in reducing the bigwig attacks as the data is not visible during the computing.
