The centralized data sharing challenges in healthcare have spurred the adoption of distributed
methods, including blockchain technology, to enhance security and privacy. This paper proposes a
blockchain-based healthcare system leveraging post-quantum cryptography (PQC) to secure sensitive patient
data, stored on a permissioned blockchain. Discrete event simulation (DES) is used in the simulation
to represent and assess three critical processes: blockchain transactions, patient data requests, and data
encryption. We examine the dynamics of blockchain transaction processing, encryption effectiveness, and
data access inside the suggested architecture through simulation. The results highlight how post-quantum
encryption and blockchain technology can strengthen healthcare data management by resolving important
concerns about patient data sharing’s integrity and confidentiality.
