Abstract: Data stored in the cloud server is in the encrypted format because the cloud server cannot be held accountable always. The cloud server makes use of the searchable encryption algorithm to fetch the required data by avoiding the decryption process. The attribute-based keyword search allows the users to access the data that they require from the cloud server any time. This method ensures that the rights of the users who access the server are not disclosed as a public data in the cloud server which is done by generating search key by the user. But still this method poses a threat to the privacy of the information.To overcome this shortfall, this paper proposes a new scheme that utilizes short lived keywords. The proposed method uses search tokens generated in a specific time span to extract ciphertext for the users and also privacy of the generated search tokens are upheld. The proposed method does not suffer from the chosen keyword attack which is verified by the random oracle model. Moreover in the proposed method it can be proved that the two parameter time complexity and the number of attributes are proportional to each other in a linear fashion. Also this scheme is well suited for real word applications.
