Random Self-Generative Schnorr Certificate less Signcryption for Secure Data Sharing in Mobile Cloud Environments
Authors: , , , ,
Abstract: To deliver applications and services required by mobile devices, mobile cloud computing adopts cloud computing. Cloud computing assists data sharing among authorized users through data stored on cloud servers. Data sharing implies distributing data resources to multiple users or applications with the utmost security. But maintaining security while transferring data in cloud computing is an important challenge. In conventional algorithms, data sharing in a secure environment and control policies in accessing the data for authorized users are the biggest concerns to deal with. To handle these sensitive issues and to eliminate drawbacks by conventional algorithms, a novel technique termed Random Self-Generative Schnorr Certificateless Signcryption-based Secured Data Sharing (RSGSCS-SDS) is proposed in this work. The proposed work improves the required security in transferring data in mobile cloud environments. In this approach, initially the information of registered mobile cloud users can be stored in cloud server for getting access of permission for various services. Using the proposed RSGSCS algorithm, for each registered user, the cloud server generates private and public keys. Depending on the attributes of the policy, the authorization of the user can be verified by the cloud server after receiving the data access request. After receiving the authorization of the user, the data requested can be transmitted in the form of cipher text with a digital signature. This digital signature is verified by the user at his end, and the data is decrypted. This ensures that only users with authorization can access the original content, and this step improves the security of data sharing. The efficacy of the RSGSCS-SDS procedure is evaluated through key metrics like storage overhead, computational time, and data confidentiality rate. Experimental results demonstrate the effectiveness of the proposed method in enhancing secure data access in mobile cloud environments.
