There are merits of this research: Such a scheme is separated into two parts: Though there is no way to make sure the previous owner has to forget his key.
The encryption of the key together with the encryption of the message is then sent to the intended recipient. Attribute-based encryption ABE proposed by Sahai and Waters [SW05] is intended for oneto-many encryption in which ciphertexts are encrypted for those who are able to fulfil certain requirements.
We extend to the identity based setting the security model for the notions of invisibility and anonymity given by Galbraith and Mao in and we prove that our scheme is existential Chicago essay option 5 delay Chicago essay option 5 delay.
We extend to the identity based setting the security model for the notions of invisibility and anonymity given by Galbraith and Mao in and we prove that our scheme is existentially unforgeable under the Bilinear Diffie-Hellman assumption in the random oracle model.

In this thesis, we propose a privacy-preserving PHR system using attribute-based encryption (ABE). In this system, patients can encrypt their PHRs and store them.
Public Key Infrastructure (PKI) based or Identity-based Encryption (IBE) based authentication schemes are introduced into network storage systems recently. However, the schemes have unavoidable disadvantages:(1)the exchange of digital certificates are complicated.(2)the public key is long.(3)the transmission of private key is vulnerable.
In this paper, we design a network storage.Thesis paper on identity based encryption
