Abstract
Supply Chain Management involves the coordination and management of various
interconnected activities and processes across different organizations and functions
within a supply chain. Real-time monitoring, efficient data handling and secure
business transactions are vital for effective operations of supply chain management. As
regards, temperature-controlled supply chain system or „cold chain network‟ there arise
certain core challenges. Extraneous factors could impact the operating environment.
Security risk in cold chain network can affect the supply chain's integrity and
auditability. Our proposed layered architecture – “SiC-Chain” provides real-time data
collection, seamless storage, and secure communications for cold-chain applications.
SiC-Chain architecture has been designed with three types of operations namely SiC-
Chain Enrollment, SiC-Chain transactions and SiC-Chain Secure IoT.For
implementation of SiC-Chain, the fishing industry has been identified as an application.
For real time monitoring, a smart IoT device named „SiC-SBox‟ has been developed. A
user-friendly web-based application that can be used on mobile devices has been
created to provide access to the SiC-Chain system. A SiC-Chain prototype development
environment consist of SiC-SBox, SiC-Chain Backend on the Cloud and SiC Chain
Application with a smart Dashboard has been developed and evaluated.
To address the concern of secure transactions within the supply chain management
entities, SiC-Chain architecture employs a novel dynamic key dependent cryptographic
algorithm. This algorithm selects non-linear S-Boxes dynamically based on the round
key generated for each round. By using cryptographic techniques, the architecture
provides a secure communication channel for transmitting the sensor data to web
application. Experimental results and evaluation show that encryption of IoT data using
the algorithm can contribute to the security of cold chain applications and ensure the
confidentiality of transmitted data. The performance analysis has been done on
encryption time, decryption time, strict avalanche effect, throughput, and memory
consumption. The novel nonlinear S-Boxes used in SiC-Chain architecture was
screened for non-linearity, Differential and Linear approximation probability analysis
which showed excellent outcomes compared to other lightweight algorithms.
