End-to-End Security for Sensitive Healthcare Data with Twofish Encryption and Wireguard
Author : Thinagaran Perumal
Abstract :
The security of sensitive healthcare data is of paramount importance as modern healthcare systems increasingly depend on digital platforms for data collection, processing, and storage. Although existing solutions have made commendable progress in protecting healthcare information, persistent challenges remain—such as slow data transmission, lack of consistent end-to-end encryption, and varying system performance. To overcome these limitations, this paper presents a novel system that ensures comprehensive protection for healthcare data through robust encryption and secure cloud storage. The proposed system captures sensitive patient information from diverse sources, including EHRs and medical databases. This data is encrypted using the Two fish algorithm—a fast and highly secure symmetric key cryptographic technique known for its strong resistance to brute-force attacks. Once encrypted, the data is transmitted via Wire Guard VPN tunnels, which establish a high-speed, low-latency, and secure communication channel, thereby mitigating risks associated with data interception during transmission. Ultimately, the encrypted data is securely stored in a cloud environment that adheres to major data protection frameworks such as HIPAA and GDPR, ensuring compliance with global privacy regulations. Experimental results reveal the system's effectiveness in enhancing data security. Encryption strength fluctuated between 22% and 97% across different time intervals, with prominent peaks observed at 83% during interval 2 and 97% in interval 5. These fluctuations suggest a trend of improving security performance over time. Additionally, the system exhibits a linear relationship between encryption time and multiplication depth, with processing time increasing from 0.10 seconds at depth 0 to 0.35 seconds at depth 7. These findings highlight the system's scalability and robustness, demonstrating its capability to address critical healthcare data security issues while maintaining regulatory compliance and efficient data management.
