摘要：In the past decades, healthcare has witnessed a
swift transformation from traditional specialist/hospital centric
approach to a patient-centric approach especially in the smart
healthcare system (SHS). This rapid transformation is fueled on
account of the advancements in numerous technologies. Amongst
these technologies, the Internet of medicals things (IoMT) play
an imperative function in the development of SHS with regard
to productivity of electronic devices in addition to reliability,
accuracy. Recently, several researchers have shown interest to
leverage the benefits of IoMT for the development of SHS
by interconnecting with the existing healthcare services and
available medical resources. Though the integration of IoMT
within medical resources enable to revolutionize the patient
healthcare service from reactive to proactive care system, the
security of IoMT is still in its infancy. As IoMT are mainly
employed to capture extremely sensitive individual health data,
the security and privacy of IoMT is of paramount importance
and very crucial in safeguarding the patient life which could
otherwise adversely affect the patient health state and in worse
case may also lead to loss of life. Motivated by this crucial
requirement, several researchers in tandem to the advancement in
IoMT technologies have continuously made noteworthy progress
to tackle the security and privacy issues in IoMT. Yet, many
possible potential directions exist for future investigation. This
necessitates for a complete overview of existing security and
privacy solutions in the field of IoMT. Therefore, this paper aims
to canvass the literature on the most promising state-of-the-art
solutions for securing IoMT in SHS especially in the light of
security, privacy protection, authentication and authorization and
the use of blockchain for secure data sharing. Finally, highlights
the review outcome briefing not only the benefits and limitation
of existing security and privacy solutions but also summarizing
the opportunities and possible potential future directions that can
drive the researchers of next decade to improve and shape their
research committed on safe integration IoMT in SHS.
