The relentless iteration of medical information technology has positioned the hospital computer communication system as the central nervous system of modern healthcare infrastructure. This system is entrusted with the storage and transmission of highly sensitive data, including patient diagnostic information, comprehensive electronic medical records (EMRs), and critical clinical decision support plans. However, the inherent complexity of hospital network environments, coupled with the continuous evolution of cyber-attack methodologies, has led to increasingly prominent security vulnerabilities within medical communication networks. Incidents of data leakage or tampering pose a direct threat to patient privacy and safety, while the manipulation of diagnostic and treatment information can severely disrupt the continuity of care, potentially leading to life-threatening risks in extreme scenarios. Blockchain technology, characterized by its decentralization, immutability, and cryptographic security, presents an innovative pathway to address these inherent security flaws. Its distributed ledger structure ensures data integrity and provides a transparent, auditable trail for all transactions. This paper, building upon this premise, conducts a systematic study on the construction of a robust security protection system for hospital computer communication networks, supported by blockchain technology. We propose a framework that leverages blockchain to create a secure, tamper-proof repository for access logs and data transaction records, ensuring the traceability and non-repudiation of all data access events. The study details the architectural integration of blockchain within existing hospital information systems, focusing on modules for identity and access management, secure data sharing between departments, and automated audit compliance. By providing a reference model that enhances data confidentiality, integrity, and availability, this research aims to contribute to the development of more resilient and trustworthy medical communication infrastructures, ultimately safeguarding patient welfare and the operational continuity of healthcare services.
