Hybrid cryptography for cloud computing

Abstract

In the present scenario, we come across millions and trillions of data in our daily lives which can be handled by a data center. Cloud is the data center that enables users to access the files and applications from almost any device and any geographical location as computing and storage take place on servers in the data center instead of the user device locally. It facilitates users with services like Software, Applications promptly without any hazard. Though the cloud has mesmerized the world with its advanced capabilities still there is safety concern involved in it because the cloud is shareable. All security components must ensure data security for every user. In this study report, a new security model using Hybrid Cryptography is designed as data in the cloud is vulnerable to issues like unauthorized data access, integrity violation, identity management, etc. Hybrid Cryptography comprises both symmetric and asymmetric algorithms. Encryption of communication requires Symmetric-key encryption whereas data exchange is taken care by the Public-key encryption technique. RSA algorithm deals with Authentication, blowfish algorithm ensures Data Confidentiality, and Secure Hash Algorithm-2 deals with Data Integrity. The present study concluded that advanced methods provide high data security over the internet and provide services on demand effectively without delay or error. © 2021 IEEE.
