A Secure Access Control Model for E-health Cloud

In the contemporary digital era, access control is one of the security issues in the modern Electronic Healthcare System (EHS). In particular, the E-Health Cloud (EHC) needed a secure and reliable access control to access the EHC resources. In the past, several attempts have been made to provide secure and reliable access control (AC) to the EHS. But, due to lack of trust and dynamic nature of EHC, the model will suffer from different types of attacks and threats. The provided Access Control Models (ACMs) does not provide complete security to EHS. So, in this paper, we have proposed a Secure Access Control Model (SACM) for E-Health Cloud. The proposed model dynamically calculates the trust degree of the users based on their behavior. The computed trust degree will be used for adjusting the access view of the user. The access view is controlled with the help of access control rule set. We also verified our proposed rule set by using CPN Tools.
