Security Implementations in IoT Using Digital Signature

摘要

In recent advancements, different types of embedded IoT devices are connected with the wired or wireless network and continuously access the internet for communication. Cybercriminals are finding vulnerabilities on IoT devices and compromise them to launch massive attacks (e.g. DDoS, Spamming, MITM, RFID Skimming) to destroy the network. IoT devices having default authentication credentials are an easy target. To avoid cybercriminals, we need a more sophisticated authentication mechanism embedded with existing security measures. Digital signature has become an integral part of IoT to restrict illegal users. The digital signature verification process is a time-consuming operation and not advisable in IoT however we can minimize the time of verification through some optimization schemes. This paper summarizes all the existing digital signature implementation aspects in IoT and states their technological properties as well as features and loopholes.
