Intheprocessofcontinuousinformatizationinmedical field, to solve the challenge of massive medical data, espe- cially the security storage problem, major companies have launchedsometargetedsolutionsforsafestorage.erefore, itisofpracticalsignificancetocarryouttheresearchonthe security storage of medical data in cloud computing environment. eInternetofings(IoT)isanewparadigm.Mishra A K believes it is important to understand the attacker’s behavior and predict what it may take while designing a defense mechanism.
