Cryptography Practices in Healthcare System: A Review

Abstract

This paper provides a detailed discussion on how cryptography techniques have been essential in changing the healthcare sector. Because of the emergence of various healthcare applications and the increase in the amount of data in the healthcare sector, there is a need for ensuring that the data are protected. In this paper, we will be looking at the capabilities of cryptography, which can help in solving problems and ensuring security in future healthcare systems. This paper focuses on cryptography in healthcare systems, which is made up of practices and methods that ensure that sensitive healthcare information is encrypted, authenticated, hashed and keys are managed securely. This paper provides an overview of cryptographic evolution and concepts. It also looks at some of the challenges that may affect the use of cryptography in practice. Overcoming such issues will require a pragmatic and structured strategy. The paper offers pragmatic suggestions that will help in utilizing cryptography in an efficient manner within real-world systems hence, the paper proposed an implementation framework integrating encryption, authentication, key management and auditing. These findings offer a way forward for policy-makers to increase the security and resilience of EHRs within the public health care system through empirical knowledge. The paper ends by making actionable suggestions for the health care organization and future research direction.
