A Collaborative Approach to Cloud-Based Functional Packaging: Sharing Intelligence Data Securely

Abstract

In cloud data sharing, ensuring security and privacy for shared files is of utmost importance. However, this becomes a challenging task, especially in an environment where membership changes frequently, and when dealing with untrusted clouds that may be susceptible to collusion attacks. To address these issues, we have developed a protected multi-proprietor data sharing plan for element bunches in the cloud. The plan incorporates AES encryption, allowing any cloud client to securely share data with others. This approach not only ensures security from untrusted users but also allows group members to split and access data securely from the cloud. Our proposal minimizes storage overhead and encryption algorithm costs, making it a practical and efficient solution for a large number of users. We've designed a secure data sharing method for dynamic members, facilitating secure key distribution without the need for a secure communication approach. Instead, users can obtain their security keys securely from the group manager. The data sharing process in our system involves multiple levels of security for a multi-owner scenario. Initially, the user selects a text-based password (OTP), which is automatically generated and sent to their corresponding email account. Upon completion of the authentication and key generation process, the shared data is encrypted using a secure algorithm. By employing these concepts, our system ensures scalability and flexibility in sharing data within the cloud environment.
