Integrity based Authentication and Secure Information Transfer Over Cloud for Hospital Management System

Cryptography has been utilized to address security issues on various administrations. It is essential to secure information and to guarantee the secure exchange of medical information. Symmetric key crypto-algorithms are quick and incredibly secure because of their extraordinary key size. Amidst the other symmetric crypto-algorithms, Blowfish algorithm has indicated prevalence in execution. SHA3 and Diffie Hellman algorithms among the others exhibited fantastic security since it is well known to have no effective attacks. Right now, a large portion of the calculations depends on symmetric key or asymmetric key to verify data. The vast majority of the applications need trustworthiness and confirmation of information. The proposed application has a hybrid approach for safeguarding data. The framework joins private and open key cryptography idea for accomplishing the objectives of security (CIA). The secrecy can be accomplished utilizing symmetric key Blowfish calculation. Integrity is accomplished through SHA3. Secure information transmission is guaranteed using the Diffie-Hellman key exchange algorithm. The EC2 which is Amazon web service’s web server provides scalable computing in the amazon cloud. The S3 is the simple storage service involved in the proposed work which is used to store and retrieve information or data at any time and place.
