Secure Data Sharing in Scalable Mobile Cloud Environment using HABE with Re-Encryption

摘要

As cloud is a semi-trusted third-party entity, sharing of confidential data may not be secure. To achieve security many cryptographic algorithms are adopted. For better security and scalability of sharing data over cloud from mobile devices, HABE along with Group Key mechanism is used. With this the data are stored securely in cloud and the system is scalable for group communication. To reduce computational overhead during revocation Proxy re-encryption technique is used. It also improves the performance of the mobile users by leveraging the process of regenerating the keys onto the server side.
