A Scheme for Improvement of Security and Privacy in Mobile Health Systems by Using SIM Card

Nowadays, mobile devices are going to be widely used in the field of e-health services. Therefore, the security and privacy of users in e-health are considered as major challenges. Due to accessibility nature of mobile, multiple communication capabilities and malware expansion, security in this area is facing major challenges. This article provides a solution to improve the security and privacy of mobile health on smartphones. Accordingly, a mechanism is proposed for obtaining a health SIM card by the applicants. Here, some communication protocols necessary in different treatment settings are provided to enhance the security of transactions between healthcare providers and patients who use mobile phones. Considering the importance of reducing the computational overhead, the elliptic curve cryptography is applied in the      proposed protocols. In addition to security, attention has also been paid to anonymity and privacy of      patients. Furthermore, a solution is provided for secure storage of information. Finally, the proposed plan is compared with other studies, and the computational overhead is evaluated and the security of the        protocols is proved by Avispa tools.
