Proof of Elapsed Storage and Time - Data Storage as a Service:Secure Multi-Tenant Database Management System
Moshe Battula · 2023
Blockchain (BC) based cloud computing is an innovative approach that combines the principles of BC technology with traditional cloud computing infrastructure to offer enhanced security, transparency, and decentralization in cloud services. A cutting-edge solution in the realm of Multitenant data storage, utilizing BC technology to establish a highly secure and tamper-proof environment for managing multi-tenant data is proposed in this research. Multichain, an open-source private BC platform, is introduced offering users unprecedented flexibility and control. The Data Storage as a Service (DSAAS) application is presented as a versatile platform that harnesses BC technology for secure data storage and sharing among participants in the BC network. The Proof of Elapsed Storage and Time (PoEST) consensus mechanism, is a unique algorithm employed primarily in permissioned BC networks, combining elements of Proof of Elapsed Time (PoET) and Proof of Storage (PoSt) to ensure robust data security and consensus in the system. This amalgamation of technologies showcases the potential for enhanced data security and management in the evolving landscape of the Internet of Things (IoT) and BC applications. The performance of the proposed method shows a good performance of 86.93% Genuine User Rate, 1.05ms Responsiveness, and 78.05ms Time Complexity.
