Mitigating Security Issues in Cloud Environments Using Enhanced Hybrid Secure Algorithm

Abstract

Cloud computing has emerged as an infrastructure-based and software-based model for several data storage applications like shared storage pools, networks and servers. While numerous research works were being carried out in recent years, securing the data in a cloud environment has emerged as a challenging area of concern. To mitigate the security aspects, a novel security algorithm for cloud computing called as, Enhanced Hybrid Privacy & Secure (Enhanced HPS) Algorithm by the employment of symmetric cipher AES and asymmetric cipher RSA, has been formulated and investigated properly. The chief intention of the proposed algorithm is to improve the security over the existing algorithms. The proposed strategy incorporates three distinct security scanners with divergent selections based on the request from concerned party for usage in cloud computing. The performance of the proposed algorithm is evaluated in terms of encryption time, decryption time, time to encrypt the data and upload it to the cloud server, time to decrypt the data wile downloading the file from the cloud server, key generation time and key updation time. The proposed algorithm is compared with the well-evaluated existing cloud security-based algorithms like RHIBE_AES, RHIBE_HYBRID, RHABE_AES and RHABE_HYBRID. Simulation results clearly revealed that, the proposed algorithm outperforms all the existing cloud security algorithms in terms of the aforementioned parameters.
