Cyber Physical Data Security Mobile Healthcare

Abstract
Attribute-based encryption (ABE) gives a promising solution for flexible access control over sensitive personal health records in a mobile healthcare system on top of a public cloud infrastructure. However, ABE cannot be just applied to lightweight devices because of its too much computing cost during decryption. This problem could be solved by giving significant parts of the decryption operations to very powerful computations such as cloud servers, but the rightness of the computation would be at stake. An effective countermeasure scheme for securing resource-limited mobile healthcare systems and provide a great security proof in the standard model, demonstrating that the proposed scheme is secure against our attacks is proposed. The experimental analysis shows that the intended scheme provides the similar performance compared with the previous commitment-based schemes and outperforms the MAC-based scheme.
