Data Sharing in Cloud Storage by RSA based Encryption
S. Monika, M. Jawahar · 2015
In cloud, the data sharing is the most important functionality that has to be done securely and efficiently. The main problem which we are facing in cloud storage is how to share the data effectively. Although, there are many techniques that are developed to encrypt the data in the cloud for secure storage and sharing, we cannot able to share data flexibly with others. In this paper, a public-key cryptosystem that produces a constant-size cipher text is introduced. Here, the secret keys are accumulated together and make them as a single compact key. Other than the files that are encrypted and present outside the set remains trustworthy. These accumulated keys are sent secretly to other users or to be stored within limited secure storage. Thus, our KAC enables efficient data sharing in cloud storage with confidentiality and integrity.
