Title: Developing Ensured and Effective Bio-Security for Cloud Services

The demand for remote data storage and computation services is increasing exponentially in our data-driven society, creating a pressing need for secure access to such data and services. This paper proposes a biometric-based authentication protocol designed to provide secure access to remote cloud servers. The approach leverages biometric data from users as secret credentials, deriving unique identities that facilitate the generation of private and session keys essential for secure communication. Our comprehensive security analysis, including a formal Real-Or-Random (ROR) model examination and verification using the Automated Validation of Internet Security Protocols and Applications (AVISPA) tool, highlights the robustness of the proposed system against various adversarial attacks. Experiments demonstrate the efficiency and utility of the proposed approach. Keywords: Authentication, biometric-based security, cloud service access, session key
