Protecting Cloud Computing Environments from Malicious Attacks Using multi-factor Authentication and Modified DNA Cryptography

Abstract

Introduction: Cloud computing has become an essential technology for data storage and sharing, but security concerns remain significant challenges. Authentication is one of the critical components of cloud security. Various authentication schemes have been proposed to ensure the confidentiality and integrity of cloud data. Method: This research paper reviews the state-of-the-art three-factor authentication schemes based on smart cards, biometric authentication, and elliptic curve cryptography. The paper also presents a comprehensive overview of DNA cryptography algorithms, which have recently gained popularity due to their unique features in cloud data security. The paper further compares the DNA cryptography algorithms and discusses their advantages and disadvantages in terms of security and performance. Results: Finally, the paper proposes an efficient and secure DNA-based authentication scheme for cloud computing. This scheme is validated using all these types of data, and its performance is evaluated in terms of encryption and decryption times. Decryption takes 60 seconds on average and encryption 40 seconds on average. Conclusion: As a final evaluation, it establishes that the proposed system can provide secure cloud services.
