Secure Sharing of IOT Data in Cloud Environment Using Attribute-Based Encryption

Abstract

Storage of data security has emerged as a basic necessity for both large- and small-scale industries. Cloud computing is internet-based computing technology in which people can work with their application with a high level of security in Internet of Things (IoT) enhanced devices. Cloud computing also provides privilege to store data that are collected from the devices in server side. Confidentiality and integrity of data play a major issue in cloud computing while preserving the IoT data. In this paper, the security of data is achieved by performing clustering and further applying cryptographic technique to the clustered data gathered from the devices that connected to the internet. Security of data can be improved by using a prominent cryptographic technique Attribute Based Encryption (ABE). Initially, the documents are clustered using the EM algorithm and clustered results are stored in various parts of the cloud. These documents are secured and can be accessed by the user who satisfies the attributes. In some cases, if the users’ attributes are not satisfied with the documents, it cannot be accessed by the corresponding user. Thus, the data from various devices are encrypted and maintained by the owner securely.

Design of safe sharing method of power core data in smart grid environment

“…In the smart grid environment, the power core data not only includes real-time data in the process of power production, transmission and consumption but also involves related information in all aspects of power grid planning, design, construction and operation, which is of great significance for the normal operation and intelligent management of power system . Data security and privacy protection are the key issues of power core data sharing and the smart grid needs to obtain accurate power core data in real time for monitoring and control [3][4]. Reference [5] puts forward a fine-grained flexible access sharing method based on blockchain.…”

CD-ABSE: Attribute-Based Searchable Encryption Scheme Supporting Cross-Domain Sharing on Blockchain

“…Based on the need of medical data, Niu et al designed a data sharing scheme that can protect users' privacy by using ABE [22]. Kanimozhi and Victoire proposed a scheme for data sharing of the IOT based on attribute-based encryption [23]. By performing clustering and the collected data and then encrypting it in the cloud, the confidentiality and integrity of the data are guaranteed.…”
