Data Integrity Audit Based on Data Blinding for Cloud and Fog Environment

Abstract

Cloud-fog computing is a novel computing model that expands the functionality of cloud computing, which provides various services through fog nodes. The issue of traditional data integrity auditing are low data security, slow data processing speed and low communication efficiency. To solve these problems, this paper proposes a data integrity audit scheme based on data blinding. This scheme uses the edge devices in the transmission node to establish a fog computing layer between the cloud service provider and the data owner to reduce transmission delay. The subordinate distribution relationship and weight between fog nodes dynamically allocate the optimal path and transmit the data to reduce transmission delay. At the same time, a blind factor is added to the integrity audit in the evidence generation process to avoid data leakage. This paper gives a security model and security proof based on computational Diffie-Hellman (CDH) assumptions. The experimental results show that the fog computing layer and blind factor are introduced into the data integrity audit process, which can reduce the data communication delay effectively and improve the security of data audit.INDEX TERMS Cloud and fog computing, data blinding, integrity audit, cloud storage.

Dificultades e importancia de la auditoria informática

“…Seguridad de datos en la nube (Bian, Fu, Shao, & Zhang, 2022 ) ciertos proveedores de servicios en la nube pueden eliminar ciertos datos que no son recurrentes. Con gran probabilidad que estos ya no se puedan recuperar.…”

“…El fundamento se basa en la idea de que el riesgo comercial no se puede medir y, por lo tanto, no se puede reflejar en las tarifas. (Bian, Fu, Shao, & Zhang, 2022 ) Afirman que los problemas de la auditoría de integridad de datos tradicional es la baja seguridad de los datos, la baja velocidad de procesamiento de datos y la baja eficiencia de la comunicación para esto presentan un esquema de auditoría de integridad de datos basada en "data blinding". (Bruma, 2021) actualmente la tecnología en la nube se ha convertido en un componente importante para el uso corporativo e industrial, etc.…”

Investigation on storage level data integrity strategies in cloud computing: classification, security obstructions, challenges and vulnerability

“…Despite the availability of various data services, data owners are apprehensive about entrusting their valuable data to cloud service providers (CSPs) for third-party cloud storage due to concerns about the integrity of the CSPs [13,16,17], and the shared nature of cloud storage environments. Cloud computing primarily encompasses data storage and computation, with Infrastructure as a Service (IaaS) closely linked to cloud storage.…”
