Abstract |
|
This paper propose a new idea to securely share the data in cloud storage. The paper explores a new Public Key Cryptosystem, which uses Single Master-Key Technique to delegate the data/files from one user(say sender A) to the other user (say receiver B).This cryptosystem produces a fixed-size (comparatively small) ciphertexts such that, the rights of decrypting any set of ciphertexts can be transferred efficiently in cloud. This could be possible by generating a concise key-we call it as single-master key- which encompasses the power of all the encryption key of the set of data/files to be transferred. The other files/data will be kept secure and confidential. This concise key can be sent to others or can be stored in a smart card and it requires very limited and secure storage. |
