MULTI-LAYERED AUTHENTICATION AND ENCRYPTION FOR CLOUD SAFETY

Abstract: This paper introduces Cloud Safety, a robust multi-factor authentication (MFA) framework that integrates password-based authentication, Time-based One-Time Password (TOTP), and SMS OTP to enhance identity assurance in cloud environments. The framework addresses critical vulnerabilities in traditional single-factor systems—such as phishing, brute force, and replay attacks—by implementing layered security controls without compromising usability. Additionally, encryption mechanisms are applied at the data layer to protect stored information. Designed for real-world deployment, Cloud Safety emphasizes low-latency performance, scalability, and adaptability to modern threat models. Comparative analysis and implementation results demonstrate its effectiveness in mitigating common cloud security threats while maintaining a practical balance between security and user experience. Future enhancements may include biometric integration and adaptive, AI-driven access control.
