ABSTRACT
The use of technology in the field of critical illness treatment has been one of the most powerful gifts to mankind. Medical cyber physical systems (MCPSs) are joining the virtual world with the real one. However, along with the facilities that MCPS brings is concern about the compromise of health records of patients. The safety and security of these records are a new challenge and a mission-critical task. The cyber security attacks on healthcare facilities are having a direct impact on human lives. The privacy and authenticity of the documents are a major security concern. In this chapter, we propose the use of a proxy signature-based authority delegation scheme for securely delegating the patients’ electronic health records (EHRs). In the case of a critical illness, the patient has to undergo treatment by various specialists whose treatments are in line with one other. In such a situation, delegation-based access to the her could be provided securely without compromising confidentiality. Proxy signature schemes provide delegation-based authentication and authorization. We provide an end-to-end secure solution for the implementation of a proxy signature-based delegation scheme. The proposed scheme is verified through mathematical modeling, formal verification, simulation, and security analysis.
