چکیده انگلیسی:
Presently, BlockChain (BC) gained significant interest because of its undeniable nature and related
advantages of security and privacy, BC has the power to resolve the limitations of Internet of Things
(IoT) such as data protection and privacy. At the same time, BC has high computation complexity,
restricted scalability, high bandwidth overhead and latency that is unsuitable to IoT. In this paper,
efficient Lightweight integrated Blockchain (ELIB) model is developed to meet necessitates of IoT. The
presented model is deployed in a smart home environment as an important illustration to verify its
applicability in various IoT scenarios. The resource constrained resources in a smart home takes the
advantages from a centralized manager which generates shared keys to transmit data, process every
incoming and outgoing requests. The presented ELIB model generates an overlay network where highly
equipped resources can merges to a public BC which verifies dedicated security and privacy. A set
of three optimizations are carried out in the presented ELIB model include lightweight consensus
algorithm, certificateless (CC) cryptography and Distributed Throughput Management (DTM) scheme. A
detailed simulation takes place under different scenarios in terms of processing time, energy usage and
overhead. The ELIB attains a total of 50% saving in processing time on comparing to baseline method
with the minimum energy consumption of 0.07mJ. The obtained experimental outcome indicated that
the ELIB shows maximum performance under several evaluation parameters.
