Elliptic curve cryptography based key management for the M2M local cloud platform

Machine-to-Machine (M2M) technology is one of the key enablers of Internet of Things (IoT) vision which allows communication among smart things in the network and the back end system. Ensuring security through proper key management utilization is without a doubt an important requirement of any M2M system. This paper proposed a key management scheme based on the Elliptic Curve Cryptography (ECC) for the M2M local cloud platform which consists of multiple gateways, which provides scalability to the distributed architecture of the platform while suitable for the low powered device. The scheme has been implemented as part of the M2M platform and its performance has been evaluated. The analysis of the evaluation results in terms of processing time to perform various operations will be discussed.
