Extended Cryptographic Mechanism for Secure and Scalable Data Sharing in Cloud using Multiple Keys
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 2
Abstract
Cloud computing technology is widely used now-a-days. Data sharing is an important functionality in cloud storage. Data can be outsourced on cloud and can access easily. Different users can share that data through different virtual machines but present on single physical machine. But there is one loop hole in this i.e users don’t have physical control over the outsourced data. In this project, we show how to securely, efficiently, and flexibly share data with others in cloud storage. The data owner can share the data to other users in safe way using cryptography. So sender encrypts data and uploads it on cloud. Different encryption and decryption keys are generated for different data. The encryption and decryption keys are different for different set of data. Only those set of decryption keys are shared that the selected data can be decrypted. Here a public-key cryptosystems produces a ciphertext which is of constant size so that delegation of decryption rights for any set of ciphertexts is possible. One can combine a set of secret keys to form a single key of small size which has the power of all the keys being combined. This compact aggregate key of constant size can be efficiently sent to others via secure channel like email or can be stored in a smart card.
