A Dynamic Four-Step Data Security Model for Data in Cloud Computing Based on Cryptography and Steganography

Abstract

Cloud computing is a rapidly expanding field. It allows users to access computer system resources as needed, particularly data storage and computational power, without managing them directly. This paper aims to create a data security model based on cryptography and steganography for data in cloud computing that seeks to reduce existing security and privacy concerns, such as data loss, data manipulation, and data theft. To identify the problem and determine its core cause, we studied various literature on existing cloud computing security models. This study utilizes design science research methodology. The design science research approach includes problem identification, requirements elicitation, artifact design and development, demonstration, and assessment. Design thinking and the Python programming language are used to build the artifact, and discussion about its working is represented using histograms, tables, and algorithms. This paper’s output is a four-step data security model based on Rivest–Shamir–Adleman, Advanced Encryption Standard, and identity-based encryption algorithms alongside Least Significant Bit steganography. The four steps are data protection and security through encryption algorithms, steganography, data backup and recovery, and data sharing. This proposed approach ensures more cloud data redundancy, flexibility, efficiency, and security by protecting data confidentiality, privacy, and integrity from attackers.

Quantum Attack-Resistant Security System for Cloud Computing using Lattice Cryptography

“…In [33], the authors designed a data security model driven by steganography and cryptography for cloud computing data to address issues which include but not limited to data theft and data manipulation. A four-phase model driven by AES-256 and RSA cryptosystems, LSB steganography technique and identity-based encryption (IBE) was proffered.…”

Performance Comparison of Xen AND Hyper-V in Cloud Computing While Using Cryptosystems

“…Cryptography is widely used in cloud computing to achieve more security and trusting. In [13], they suggest four-steps data security model in cloud computing. They combine three cryptographic algorithms, which are RSA, AES, and identity-based encryption alongside with steganography by using least significant bit LSB techniques.…”

Cloud Computing-Based Online Sharing Method of Mass Resources in Public Libraries

“…(E i , E j , d, t) are entities (i.e., nodes and sums) of public library's massive resources in the directed graph under the condition of network environment and culture construction, S i,j (t) is the subspace clustering distribution of public library's massive resources under the condition of network environment and culture construction, and T i,j (t) is the information exchange time of file sharing scheduling. In order to reduce the time of public library's massive resource sharing and scheduling under the condition of network environment and culture construction [13,14], it is necessary to model the main characteristics of public library's massive resource distribution under the condition of network environment and culture construction and define the graph model attribute set of public library's massive resource sharing and scheduling nodes under the condition of network environment and culture construction, where d represents the ontology object of public library's massive resource distribution under the condition of network environment and culture construction, and p represents the ontology distribution concept related set of public library's massive resource sharing under the condition of network environment and culture construction.…”
