Privacy-Preserving Healthcare Cloud Access Control: Registered Attribute-Based Encryption With Auditable Policy Updating
- Published
- Record updated
Summary
Researchers propose a registered attribute-based encryption (RABE) access control scheme for medical cloud environments, aimed at protecting Electronic Health Record data stored with third-party clouds. The scheme supports dynamic ciphertext updates without frequent re-encryption and outsourced decryption to reduce user-side computation, and a second variant adds consistency verification of updated ciphertexts. The authors report security analysis and experimental results, though the source text gives no specific figures.
