Enhanced Health-Care Protection Using Advanced Encryption Standard and Diffie Hellman Key Exchange Algorithm

In the modern world as technology develops, it is very crucial to secure, share and store the data. Especially, when it deals with medical data it is very important to secure that sensitive information. Sensitive information might be the pulse, temperature, or any disease-related symptoms. Such factors must not be shared unless or until with the users' permission. When any services or any user overcome the given act then the victim will be addressed in the court of law for the denial of service. Such activities must not be welcomed as in the world of modern technology; it is easy to secure the data as well as to share the data. Hence, it is significant to overcome privacy issues and security attacks. The co-factors associated with transmitting and securing data involves bandwidth and energy. Bandwidth and energy play a vital role during the transmission of data. Hence in this paper, we introduce a novel system of creating a portal for the patients who can enroll with their medical details and fix appointments with the doctor and get the prescription. First, the Nth Degree Truncated Polynomial Ring Unit (NTRU) method is used to encrypt the data collected where the private chats among the patient can be secured. Those data will be transmitted to the nearby cloud-let in an energy-efficient manner. Secondly, patients can communicate with other patients about their diseases where the disease based group can be created to share the information. Thirdly, patient's information is divided into tables and stored in the cloud for proper protection. As group chats and personal chats are involved, security is a must during communication and as an additional feature, the data are collected in a buffer format in the mobile, which paves way for reducing the bandwidth and energy consumption
