Terminal Authentication in M2M Communications in the Context of Internet of Things

Security and Privacy is a major concern in IoT and within terminal authentication is a major issue in M2M communications. Here we have proposed a set of protocols and its associated mechanism for terminal authentication in M2M systems in the context of IoT. It is based on digital signature and randomly generated credentials. The main feature of the proposed protocol is it does not depend on pre-installed keys and other tokens. It is secure and no known attack possible on this as we have shown in informal threat analysis and above all it does not depends on Certification Authority/Trusted third party and consumes very less resources. It is also very efficient and deployable that we have shown through experiments. It meets all requirement of IoT scenario like Heterogeneity, Scalability etc.
