ABSTRACT: The adopters of IoT face challenges with the surging
Internet-based attacks on their IoT assets and
inefficiencies within the technology. Unfortunately, IoT is overly distributed, still evolving and facing implementation and security
challenges. Given the above scenario, we argue that the IoT network should always be decentralized design, and security should be built by design. The paper is the design and construction of a decentralized IoT security
framework, with the goal of making emerging
IoT systems more resilient to attacks and supporting complex communication and resource sharing. The framework improves efficiency and scalability in IoT,
exposes vulnerable subsystems and components as possible weak links to system compromise, and meets the
requirements of a heterogeneous computing environment. Other features of the framework including efficient resource sharing, fault tolerance, and
distributed storage support the
Internet of Things. We discuss the design requirements and carry out the implementation of Proof of Concept and evaluation of
our framework. Two underlying technologies: the actor model
and the blockchain were used for
the implementation. Our reason for choosing the actor model and blockchain is to compare its
suitability for IoT integration in parallel. Hence, evaluation of the system is performed based on
computational and memory efficiency,
security, and scalability. We conclude from the evaluations that the actor-based implementation has better scalability than the block-chain-based
implementation. Also, the blockchain seems
to be computationally more intensive than the actors and less suitable
for IoT systems.
