A Double Tap Key based Security Model in Cloud Applications

Security becomes more complicated for the data stored in cloud applications. Cloud computing provides data storage security as a service. In cloud computing, security should be provided to the users based on the data access controlled by the cloud service provider (CSP). To improve the security of cloud applications, the study presents a unique security model based on a double-tap key mechanism in this research. The suggested paradigm combines device verification with user authentication to allow access to cloud resources. In addition to providing their login credentials, users must authenticate themselves using a double-tap key produced by their registered device as a secondary verification step. This double-tap (Pseudorandom Number Generator (PRNG) and RSA (Rivest-Shamir-Adleman) Algorithm) key is highly safe and impervious to unwanted access since it is created using a unique method that combines user credentials with device-specific data. The proposed security model also incorporates multi-factor authentication, adding an extra layer of defense against potential intrusions. Depending on the sensitivity of the data or application being accessed, users may be required to verify their identity using additional methods, such as biometric recognition or one-time pass codes, in addition to the double-tap key. The proposed model's effectiveness is validated through comprehensive simulations and tests, demonstrating its ability to thwart a range of common attack vectors, including credential stuffing and brute force attacks. Its scalability and lightweight design enable deployment in large-scale cloud systems without any overhead. Finally, the double-tap keys, proposed security model offer a robust and efficient solution to enhance cloud application security, mitigating the risks of unauthorized access and data breaches. Combining device verification and user authentication provides a comprehensive defense against the ever-evolving cyber security threats in the cloud computing environment.
