Security using Blowfish Cryptography with Distributed Keys for Data Sharing on Cloud

Abstract

Information security is very significant. The data passing to cloud may not be secured. To protect data while sending it to cloud is essential. The data should be secured by using encryption and getting data by using decryption standards. In this paper, we use the Blowfish encryption before sending it to cloud and getting the data by using the Blowfish decryption standard. Here in this cryptosystem, the single key is distributed to multiple users and it will be encrypted based on their private key and later it will be decrypted. It will be maintained by updating the keys randomly. While encryption using any other encoding system it is essential to maintain good performance and while decoding. We are using encryption and decryption by using the Blowfish standard and checking its performance while sending it intothe cloud and while receiving data, respectively.
