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.
