Abstract:
SecureERP is a centralized Oracle-based ERP system, and emerged as a single source of truth
for many allied organizations within its network. Presently, traditional approach, such as,
Service-Oriented-Architecture (SOA) and emails are used for data sharing among these
organizations. Major ERP giants like Oracle, SAP, and Microsoft offer standardized
functionality (providing pre-developed processes), while discouraging customization in the
developed processes. However, there are use-cases, where organization has to deviate from
standardized processes in order to meets its specific requirements. For example, in our usecase,
extensive customization has been implemented in Oracle Enterprise Business Suite (eBS)
during the deployment of SecureERP. This customization has inadvertently introduced
vulnerabilities, and raises concerns regarding transaction integrity and stakeholders’ trust.
The risk of single points of failure in the SecureERP system is effectively mitigated by
establishing Disaster Recovery (DR) sites; however, ensuring transaction integrity is still a
top concern. In this paper, we propose an architecture and framework, which seamlessly
integrate Hyperledger Fabric (a Permissioned Blockchain) with SecureERP system to ensure
transaction integrity and security. Our model uses a Raft-based consensus mechanism, which
is more efficient compared to PoET, Kafka, ZKP (Zero-Knowledge Proof) and Proof of Work
(PoW). Our proposed model is validated by conducting a Proof-of-Concept (POC) using
relevant technologies.
