Blind Batch Encryption-Based Protocol for Secure and Privacy-Preserving Medical Services in Smart Connected Health

Abstract

Smart connected health is a vital Internet of Things (IoT) application proposed to improve the efficiency of healthcare systems and reduce healthcare costs. However, there are many complex security and privacy-preserving concerns in medical services. Blind batch encryption provides a solution for the tradeoff between privacy and security. We propose an efficient blind batch encryption scheme from the CDH assumption, which can be proven to be suitably secure and blind. Based on this scheme, we design a protocol for secure and privacy-preserving medical services in smart connected health. We analyze our protocol in the context of six typical attacks and implement the prototype over the Intel Edison platform. The experiments show that our protocol is efficient for resource-limited devices and “cheap” communication protocols.
