Abstract: With the increased popularity and the need to store the sensitive data over the cloud, the security of stored data is a very big challenge. This work has not only investigated and rectified the susceptibility of the data in the cloud, but also proposed the technique for user authentication and server allocation efficiently. Cuckoo search algorithm (CSA) is applied for efficiently allocating the server. For maintaining the privacy of client's data over the cloud, improved attribute-based encryption (IABE) can effectively do attribute adjunction/revocation, reduce the time complexity as well as safeguard from collusion attacks. The minimum set generation, proxy key generation, file updation, and secret key updation, is modified for efficient attribute revocation/adjunction. The combination of IABE with CSA achieves the security objective and the process is enhanced efficiently.
