Blockchain based solution for secure information sharing in pharma supply chain management.

Area of Science:

• Supply Chain Management
• Blockchain Technology
• Information Security

Background:

• Traditional pharmaceutical supply chain management (PSCM) systems struggle with transparency and trust.
• Existing online pharma systems face implementation challenges.
• Key security goals for supply chain management (SCM) include authentication, confidentiality, data provenance, and auditability.

Purpose of the Study:

• To propose and evaluate a novel blockchain-based solution for pharmaceutical supply chain management (BPSCM).
• To enhance security, transparency, and trust among stakeholders in the pharmaceutical supply chain.
• To address the limitations of traditional PSCM systems.

Main Methods:

• Implementation of a three-phase BPSCM: registration, product circulation, and secure payment.
• Utilizing hashed private keys and Edwards-curve digital signature algorithm (EdDSA) for stakeholder registration.
• Development of smart contracts with cryptographic operators for secure transactions and data provenance during product circulation.

Main Results:

• The BPSCM framework effectively mitigates impersonation and collusion attacks.
• Security analysis confirms the robustness of the proposed solution.
• Performance evaluation shows favorable metrics in gas consumption, throughput, latency, and computational cost compared to standard PSCM frameworks.

Conclusions:

• The proposed BPSCM offers a secure and efficient alternative to traditional pharmaceutical supply chain systems.
• Blockchain technology can significantly improve transparency, trust, and security in pharmaceutical logistics.
• The BPSCM framework demonstrates practical viability and effectiveness for real-world application.
