Abstract

The evolution of IoT has been around for very long considering the number of devices getting connected daily. Current trends of IoT focus on Over-the-Air software and firmware updates which enable upgrading functionalities or fixing bugs of IoT devices. When OTA was introduced, it provided with multiple advantages and reducing the cost of maintaining these devices manually. But security concerns are raised on the backend OTA servers about maintaining the data privacy and security. IoT devices require data to be transmitted with the OTA servers to initiate an update sequence, which is sent in plaintext and visible to the public with the current OTA architecture. Security was not a concern until the massive worm Stuxnet which ruined the Iranian centrifuge systems and called upon the implementation of OTA software updates to timely patch up undisclosed vulnerabilities. Many industries are working on introducing secure OTA updates considering the importance and criticality of these updates. The main security issues of OTA updates are the attack and threats received on these wireless connected devices. This survey highlights the current security trends that can be incorporated with OTA, based on embedded devices, to provide a secure framework to deliver updates to remote devices without compromising the functionality and usability.
