High-Throughput Encryption for Cloud Computing Storage System

Abstract

In recent years Cloud computing has become the infrastructure which small and medium-sized businesses are increasingly adopting for their IT and computational needs. It provides a platform for high performance and throughput oriented computing, and massive data storage. Subsequently, novel tools and technologies are needed to handle this new infrastructure. One of the biggest challenges in this evolving field is Cloud storage security, and accordingly we propose new optimized techniques based on encryption process to achieve better storage system security. This paper proposes a symmetric block algorithm (CHiS-256) to encrypt Cloud data in efficient manner. Also, this paper presents a novel partially encrypted metadata-based data storage. The (CHiS-256) cipher is implemented as part of the Cloud data storage service to offer a secure, high-performance and throughput Cloud storage system. The results of our proposed algorithm are promising and show the methods to be advantageous in Cloud massive data storage and access applications.

A Secure Cloud Computing Model based on Data Classification

“…When speaking about public cloud storage, data is no longer in the hands of the user, it is actually stored on remote servers, and it is mostly spread around the globe. Deleting one file does not guarantee you that it has been truly deleted 11,12 .…”

“…To prevent data loss, keys used for encrypting data must be combined into some kind of a key escrow system. Generation of keys used for encrypting data must be truly random which will guarantee difference in two ciphers of the same clear text 10,12 .…”
