This document discusses security challenges with Internet of Things (IoT) devices and potential solutions. It first describes how the widespread use of IoT devices has introduced new security issues as hackers can easily access information without proper security measures. The document then reviews 10 different papers on techniques used to enhance security for IoT devices, including security models, access mechanisms, encryption, authentication, and more. It evaluates various technologies like RFID, sensors, artificial intelligence. Finally, the document concludes that providing a security-enabled model to secure end-to-end communication is the best short-term solution, while various approaches are needed to address different security issues in IoT.
