ORIGIN DISTRIBUTED LEDGER FOR ENSURING IT SECURITY IN CLOUD MANUFACTURING

Abstract

Origin distributed ledger is an evolving
concept for protection of production, logistics, and supply
chain networks from rogue Industrial Internet of Things
(IIoT) devices. Such rogue IIoT devices are a recognized
threat in the cloud manufacturing networks. In extreme
cases, they can be used to cause industrial a c c i d e n t s . A
b r i e f v e r s i o n o f o r i g i n i s a b o u t e n d -to-end tracking
and tracing of data and the nodes involved in creating,
modifying, transmitting, storing, and deleting it at specific
times and locations. It provides an end-to-end verifiable
and controlled computation for ensuring
trustworthiness, quality, reliability, and validity of data.
Origin has existed in computing using logging software
systems. This research is focused on threats to food supply
chains between two countries. A scenario for protecting food
supply chain from India to UAE has been modeled. This
research recognized the threat of harmful food items getting
mixed with flow of genuine products in a supply chain. The
IIoT devices used to control the flow can be authenticated
using the evolving origin distributed ledger technology.
With the help of recent design recommendations in the
literature, a model design has been created and simulated in
this research. Observations from the simulation revealed
that TCP congestions and unpredictable turnaround time for
assigning cryptographic keys to IIoT device sessions may
have to be explored in future. A collaborative design between
the two nations has been proposed. All IIoT devices not
supporting cryptography will be eliminated from the cloud
manufacturing and supply chain networks. Currently, this
design may be used for one time registration only. Future
