Abstract

The establishment of electronic health records (EHRs) for patient monitoring is a notion that has gained widespread acceptance in the healthcare sector. Patients can contact their individual doctors and seek their advice for disease diagnosis using this useful web app. This enables them to maintain a digital and electronic record of their medical records. Yet, due to the possibility of several patients trying to access them, the volume of the data uploaded to the EHR is enormous. Due to the system model's vulnerability in this situation, the data that has been obtained may be subject to various attacks and breaches, which could even result in the loss of power for data stored on the relevant EHR on the cloud. In addition to this; since the working of cloud gives access to users for retrieval of data irrespective of their location, the entire system becomes more prone to exposures and breaches. Therefore, in order to protect the data being sent over the EHR, I propose the implementation of hybrid encryption techniques in this study. Elliptic Curve Cryptography (ECC) and the Advanced Encryption Standard (AES) are utilised in a hybrid cryptographic technique (HCT) for this purpose. Asymmetric encryption is not practical for encrypting massive amounts of data because it is slower and less effective than symmetric encryption. By utilising both symmetric and asymmetric encryption, hybrid encryption can overcome these constraints. The informational communication is expected to be secured on the cloud using the HCT thus described.
