Securing Medical Data: The Integration of Advanced Encryption Standard and Blockchain

Objective: The research is to ensure the security of medical data and prevent data breaches. To achieve this objective, An efficient solution was proposed - the integration of blockchain technology with Advanced Encryption Standard (AES) encryption techniques to provide medical data security. Methods: The cryptography which served as the cornerstone of information security provides robust encryption and decryption methods to ensure data confidentiality and integrity. At the same time, the attributes of tamper-proof and decentralization in blockchain ensure the true validity and security of data. We utilized the AES encryption algorithm to secure data and integrate the encrypted data into the blockchain technology, providing a solid and reliable guarantee for medical data privacy. Results: The AES encryption algorithm was apply to blockchain technology. With this integrated solution, the security of medical data and effectively prevent data leakage was ensured. Conclusion: This solution not only addressed the issue of medical data leakage, but also provided a solid foundation for the future development of information security. Integrating blockchain technology with AES encryption provided a reliable solution for medical data security, giving both patients and medical professionals greater confidence in data security. At the same time, the combination of the AES encryption algorithm and blockchain technology is being widely applied in various other fields.
