Secure User Authentication And Data Sharing For Mobile Cloud Computing Using RIPEMD-160 And NTRU Encrypt

Abstract

Background: With mobile cloud computing's rapid growth, safeguarding data and ensuring efficient user authentication have become critical. Traditional methods are resource-intensive and vulnerable to advanced threats like quantum computing.
Objective: To develop a secure, quantum-resistant framework using RIPEMD-160 hashing and NTRUEncrypt encryption, optimizing data security and resource efficiency for mobile cloud environments.
Methods: This framework integrates RIPEMD-160 for robust user authentication and NTRUEncrypt for quantum-safe data encryption. Blockchain technology is incorporated for decentralized key management and secure transaction logging.
Results: The combined framework showed significant improvements in collision resistance, throughput, energy efficiency, and overall security, surpassing the performance of standalone algorithms.
Conclusion: This hybrid approach offers strong data protection and efficient user authentication, presenting a viable solution for evolving security needs in mobile cloud computing.
