The demand for remote data storage and cloud computing is increasing rapidly in today’s datadriven
world, creating a strong need for secure access to cloud services and user data. Traditional
authentication methods face several security challenges, making it necessary to develop more advanced
and secure techniques. This paper proposes a new biometric-based authentication protocol that uses the
user’s biometric data as a secret credential, as it is unique and difficult to replicate. A unique identity is
generated from this biometric data, which is then used to create the user’s private key, eliminating the
need to store the key and reducing the risk of theft or misuse.
The approach also introduces an efficient session key generation method using two biometric templates,
without requiring any prior shared information between communicating parties, ensuring secure
communication. The protocol is analyzed using the Real-Or-Random (ROR) model, along with informal
security analysis and formal verification using the AVISPA tool, which confirms its strong security
features. The system is capable of resisting both passive and active attacks, providing reliable protection
against common threats. Experimental results demonstrate the efficiency of the proposed method, and a
comparative study shows that it performs better than existing approaches, making it a secure, efficient,
and practical solution for real-world applications.
