Privacy Preserving Data Sharing in Cloud Using EAE Technique

Accessing and controlling data on the cloud is a low-cost method of ensuring data security. However, in cloud storage systems with untrusted cloud servers, data storage and retrieval management become a challenge. Because this new computing technology encourages users to leave their sensitive data to cloud providers, security and privacy issues over outsourced data are growing. To protect data privacy, attribute-based encryption (ABE) systems and variations are frequently used. ABE scheme are resistant to a variety of assaults. Which includes data access, interruption, interception alteration, illegal authentication, and fabrication? Existing encryption approaches, on the other hand, necessitate greater processing time and secure communications of sensitive information transport, both of which remain unsolved. The proposed scheme uses enhanced elliptic curve Attribute-based Encryption (EAE) to address this problem. EAE encrypts user data during transmission to ensure privacy. EAE generates the hash value for the encrypted data and stores it in the cloud server after completing the encryption process. To strengthen data transfer security, this produced hash value is sent to the associated users in the cloud. We deployed our scheme and demonstrated that this is both effective and versatile for outsourcing data in the cloud.
