K-RSA: Secure data storage technique for multimedia in cloud data server

Abstract

Cloud has become one of the most demanding services for data storage. On another hand, the security of data is one of the challenging tasks for Cloud Service Provider (CSP). Cryptography is one of the ways for securing the storage data. Cryptography is not a new approach instead of the efficient utilization of cryptographical algorithms is greatly needed. In this work, we proposed a Secure Hidden Layer (SHL) and Application Programming Interface (API) for data encryption. The SHL is consisting of two major modules (i) Key Management Server (KMS) and (ii) Share Holder Server (SHS) which is used for storing and sharing of cryptographic key. For this purpose, we proposed a server-side encryption algorithm, which is based on the asymmetric algorithm (RSA and CRT) for providing end-to-end security of multimedia data. The experimental results of text and video are evidence that the size of file is not much affected after the encryption and effectively stored at Cloud Storage Server (CSS). The parameters like ciphertext size, encryption time and throughput are considered for performance evaluation of the proposed encryption technique.

Randomized Block Size (RBS) Model for Secure Data Storage in Distributed Server

“…3 presents the evaluation of the cryptographic algorithm based on encryption time. Here, the proposed C-RSA technique value is acceptable and matches Blowfish, AES, DES, DNA, and BDNA [34], and is comparable with the K-RSA [12].…”

“…Here the results of the C-RSA technique have been compared with the various traditional encryption algorithms. It is observed that the results of the proposed techniques are better than the methods (Blowfish, AES, DES, DNA, and BDNA) and very close to the K-RSA [34,12]. It shows that the proposed technique requires less space for storing encrypted text files.…”

“…The cryptographic techniques require tremendous computational power while performing encryption in the cloud environment. Paul et al [12] introduced a public key cryptographic technique for video file encryption in a cloud environment. The work aims to store data securely in the cloud server and reduce computational time.…”

Safe Storage Method of Energy Big Data Center Based on Blockchain Technology

“…Due to the large number and types of energy big data, in order to improve data storage efficiency, we first conduct statistical analysis on energy big data [6]. Suppose the original sequence of the energy big data center is…”

Binary Multifold Encryption Technique for Complex Cloud Systems

“…A consistent view about both data security concerns and privacy issues presented in the survey that are faced by clients in cloud storage environments has been carried out [18]. Further to study the security in a cloud network, Secure Hidden Layer (SHL) and Application Programming Interface (API) for data encryption explained in [19]. The SHL is consisting of two major modules (i) Key Management Server (KMS) and (ii) Share Holder Server (SHS) which is used for storing and sharing cryptographic keys.…”
