cryptography for identity verification; after completing identity verification, the system produces a session key with the
server to conduct symmetric cryptography transmission.
Although the study's [16] private communication and data
collection boasts the best performance, it lacks privacy protection that can lead to data leakage. On the other hand, although
the elliptic curve technology in [17] can satisfy all of the
security requirements, it is highly complex in its computation
methodology. Meanwhile, while the public-key cryptography
suggested in [1] has a lower computation complexity in data
collection encryption compared to our approach, which
requires n) 9.68 ms of computation time when a single node
collects data from another node, our proposed method's
distributed architecture can prevent the meltdown by a certain
node suffering from cyberattacks.

CONCLUSION
This article reviews literature on health-care systems and proposes network security requirements for such systems as well
as two algorithms that satisfy these demands. Although the
proposed techniques can meet the security needs, in addition to
network security, we should also consider relevant dictates of
the general data protection regulation. Privacy and private
communication are the goals of any health-care system. The
overall security of a health-care system's design should start
with overall planning for information security, information
storage and access, and network security to ensure medical
information safety and confidentiality in health-care systems.
Currently, there is a high price to pay for any breach or modification of information caused by system failures. There is much
room for progress and discussion when it comes to the establishment of health-care systems, such as distributed management, legal regulations, network security, and the feasibility of
health-care systems.
