EAM: Enhanced authentication method to ensure the authenticity and integrity of the data in VM migration to the cloud environment

Abstract

Cloud is a prominent technology today to provide computing resources to users. In previous days, industries or enterprise users are maintaining their data on-premises. Therefore, it creates many management issues in the industries. Cloud gives solutions to industries to maintain their data in the cloud data center. As a result, many industries are outsourcing their data to the cloud. When outsourcing, the data are migrated along with Virtual Machines (VM). During the migration, the data are vulnerable to attack. As a result, the data may tamper with fault content by the adversarial. Therefore, it is necessary to maintain data authenticity and integrity verification during the migration. This paper proposes an authentication mechanism to verify the data authenticity when migrated from on-premises to off-premises. The paper proposes a novel procedure to migrate the data in the virtual machine. After migration, the data is verified for authenticity using the proposed mechanism. An enhanced hashing procedure is proposed in the paper to verify the data authenticity. The proposed authentication mechanism is simulated in the cloud environment, and results are given in the tables and graphs. The results show that the EAM efficiently provides authentication and integrity of data migrated from on-premises to the cloud data center.
