Global technological advancement in the field of Internet-of-Things (IoT) has made the connectivity ubiquitous. The IoT is so powerful that it is expanding its application to every field and thus it is predicted to connect one to three trillion devices by the end of 2025. Connected vehicle is now an emerging trend in automobile sector. A major feature of this connected vehicle technology is the capability to upgrade the in-vehicle embedded devices through firmware updates over the air (FOTA). The security of these firmware updates is very crucial because the firmware flashed onto the in-vehicle devices control various operations of the vehicle. In this regard several protocols are developed. These security layer protocols protect the binary image of the firmware only during transmission from trusted portal to end device. However, there exists a possibility that attackers can modify the downloaded binary before installation. Therefore, there is a need for secure FOTA object. In IoT context, privacy and security are the major concerns when large scale deployments are considered. Open Mobile Alliance (OMA) has set standards for FOTA. This paper presents a review of such existing standard protocols and schemes for FOTA. The short comings in existing techniques are identified and the issues are addressed.
