Abstract

Cloud Computing is an important way of communicating and share data over Internet. Cloud Computing enables transmission of data over Internet and resource utilization at data centers. But during data sharing and resource utilization security plays a vital role since the chances of attacks increases. The data to be stored at data centers needs to be retrieved without any data loss and attack. Hence a multi key based data retrieved with encryption is proposed previously but the techniques require more computational time and hence increase the overall cost. Here in this paper a new and efficient is implemented which uses the concept of Cipher text policy attribute based encryption using elliptic curve based key generation. The implementation is based on the concept of generating a new attribute for each and every data to be send and encrypt the data using the generated attribute and forms a tupple and stored at the storage site. The receiver then authenticates himself and enters the attribute and hence decrypts the data. The proposed methodology implemented here provides efficient retrieval of data over cloud as well as reduces computational time and cost.
