Abstract

Due to high volume, variety and velocity of big data, organizations apprehend to store these huge data on the cloud environment, because of its scalability and processing power services in terms of pay as you use. Due to the security demand of data in terms of storage and access structure, data owner cannot store data on cloud in plain text format and hence has to define the encryption algorithm and access structure for the data that has to be stored in the cloud infrastructure. In this paper we propose a new way of encryption method called as a time domain attribute based encryption by embedding time into both cipher text and keys to achieve an end to end security of big data in cloud. The proposed time domain attribute based access control (TDAAC) algorithm shows how ciphertext policy attribute based encryption (CP-ABE) with time domain and access rights can assist in protecting data against adversaries or deliberate unauthorized access to data that is stored in cloud.
