Performance Comparison of a Blockchain-Based Medical Data Encryption Scheme

A dataset comparing the computational and storage overhead of a proposed Ciphertext-Policy Attribute-Based Encryption (CP-ABE) scheme designed for the Internet of Medical Things (IoMT). The data was generated by Hao Yuan and uploaded to figshare on 2026-05-27. Performance evaluation indicates the CP-ABE algorithm in this scheme outperforms existing solutions in computational overhead.

Use Cases

• Benchmarking encryption schemes based on computational overhead metrics mentioned in the description
• Evaluating blockchain consensus latency for medical data applications based on the 100-node Hyperledger Fabric test
• Analyzing key management efficiency based on the reported key update propagation delay of 1.52 seconds

Strengths

• Performance metrics are provided, including a consensus latency of approximately 280 ms and a key update propagation delay of 1.52 s
• The dataset is small (5.5 KB), facilitating quick download and inspection

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
