Abstract
Cloud computing is widely utilized for storing and managing enormous data generated by various devices, wherein cyber-attacks is the challenging aspect due to the distributed and multi-user nature. Thus, providing secure access control with efficiency processing is challenge. To address the issue, the proposed multifactor authentication model with threelevel access control mechanism is designed. In the first level, authenticated users are granted read-only access by verifying the identity and passwords. In the second level the permission is designed to perform downloads using the biometric verification. And the third level devised for both reading and downloading of data through the identity, password and biometric checking. Besides, the data security is enhanced using the proposed optimized encryption algorithm with double-layer Rivest, Shamir, Adleman (RSA) encryption and optimal key generation using Chebyshev Superb Fairy-wren Optimization (CSFwO) algorithm. Thus, the proposed model ensures robust confidentiality, integrity, and resistance to cryptographic attacks by optimizing computational performance for largescale cloud-enabled network scenario.
