Summary To provide privacy protection in mobile health care system, medical users typically encrypt their personal health information before publishing it to the health care center. And other medical users download, decrypt, and process it using an access control protocol. However, current access control protocols are mainly focusing the privacy of personal health information and lacking the protection for medical users' real identities, leading to a variety of security issues. At the same time, current access control protocols for mobile health care systems are usually based on bilinear map, resulting in high computation costs. Observing the above issues, we introduce a novel access control protocol with privacy‐preserving called Access Control for Mobile Healthcare System (ACMHS). Similar to protocols of this field, ACMHS can provide privacy protection for mobile health care systems. However, different from other well‐known approaches, ACMHS uses pseudonyms instead of real identities, which can provide privacy protection for medical users' real identities. Moreover, to reduce the computation cost of bilinear map, we introduce the algebraic signature to ACMHS and design a novel access control protocol, which is much more efficient than current bilinear‐map‐based protocols. By doing so, ACMHS can achieve high efficiency while still enjoying required security requirements. Experimental results show that ACMHS is feasible for real‐world applications.
