A Hybrid Cryptographic Algorithm for securing medical data in Cloud Computing Environment

In the past few years, the researchers focused on cloud computing security, because of medical data usage and its importance. Therefore, data security on medical data is an important issue, while storing it on clouds. Decentralized protection safeguarding prescient displaying enables numerous organisations to learn about a more generalize on medical services or genomic information by sharing the halfway prepared models rather than patient-level information, while evading dangers, such as single-purpose of control. One of the most important aspects of human life has become restorative care, which has led to a dramatic increase in therapeutic data. Although these advancements pose serious security risks and concerns about the movement of information, they also raise serious concerns about data tracking and recording. Even if the patient’s life is in jeopardy, these security and protection issues of medical information could result from a delay in treatment. A high level of data transit and storage security can be achieved through the use of cryptography. Traditional symmetric and asymmetric have various drawbacks in terms of their design. In order to ensure the privacy and data security at high level, the research work implemented the new hybrid technique. Elliptic curve cryptography (ECC) and the SHA-256 Cryptographic Hash Algorithm (SHA-256) are being combined in this article to create a hybrid algorithm. Proposed methods for patient data security and confidentiality have been tested and the results proves that it outperforms existing methods. To overcome the drawbacks of both symmetric and asymmetric cryptography, hybrid cryptography is employed.
