Secure Communication With Data Analysis and Auditing Using Bilinear Key Aggregate Cryptosystem in Cloud Computing

Abstract

In the current technological world the cloud computing becomes very popular, where anyone can use the internet, and the remote servers to give retrieve data as well as applications. The users can use such applications via the cloud communications without any installation. That is using some web services any computer can access and maintains data of end-users. Even though the cloud computing environments provide lot of benefits in data and application accessing, there are many questions still coming up on how to gain a trusted environment for securing data and applications in clouds from hackers and intruders. Cloud storage should be able to store and share data securely, efficiently, and flexibly with others in cloud storage. Based on the number of decryption keys to be shared the cost also increased. In public key encryption both the keys (encryption key and decryption key) are different. This paper proposes a new era of bilinear key aggregate cryptography. To produce constant length cipher text is also one of important task that we have materialized. In this paper, we propose a simple, efficient, and publicly verifiable approach in cloud computing which provide security to data during data transfer between different users. Here we introduce Bilinear key aggregate cryptosystem. In the Proposed Approach, by utilizing public key based homomorphic authenticator with random masking privacy preserving Algorithm for secure data transmission. The new method bilinear aggregate signature can be used to achieve key auditing. Key auditing avoids the computation complexity
