For specific users in cloud computing, broadcast encryption offers a viable method of data access management. To ensure that only the intended users can access the data, a data uploader can create a ciphertext for a group of selected users. But with the quickly rising number of In order to encourage user cooperation, it is desired to increase the receiver set’s capacity. Receiver extension cannot be supported by the broadcast encryption technologies in use today. In this project, authors address this issue and offer a solution for the first time. Considering the advantages of identity-based cryptography, we propose the idea of EIBBE: a broadcast encryption-based flexible data access control with expandable receiver for cloud computing. By introducing a new receiver set S0 without re-encrypting it, it enables the authorized user to increase the receiver set S specified in the IBBE ciphertext. Users in S and S0 can successfully access the data. Additionally, the maximum number of extended receivers is decided by the data uploader. After that, present a detailed construction of the EIBBE and do a thorough security study of the suggested scheme. Finally, show the effectiveness and viability of the plan
