DPC2-CD: a secure architecture and methods for distributed processing and concurrency control in cloud databases

Multi-tenant public cloud architecture is plagued by numerous security issues in cloud computing, including host access restrictions, unlawful access, and data security. The National e-governance division is discouraged from launching numerous e-governance projects, including the Adhaar-digital locker, e-sign, financial-PayGov, Jan Dhan Yojna, E-participation-MyGov, and e-Sampark. Due to the limited computational capabilities in the private cloud, the performance of the applications will also be impacted. In these e-governance initiatives, a significant amount of user data will be produced that will be impossible to handle on the private cloud. To manage the user's data, a private, secure space with high-performance computing resources in a public cloud environment will be required. This article presents DPC 2 -CD , a secure architecture, and methods that (i) offer a secure private space in a public cloud environment, (ii) perform distributed processing and concurrency control of cloud databases, and (iii) guarantee the high performance of e-governance applications. The National e-Government Division will be able to successfully implement the numerous e-Government projects with the help of our proposed solution.
