Key Policy Attribute Based Encryption (KP-ABE) scheme is a public key encryption technique that is designed for one-to-many communications. In this scheme, data is associated with the attributes for which a public key is defined for each.

although it requires the data owner to be present and aid in the re-encryption task [7]. As a next step in the evolution of such techniques, proxy re-encryption has been combined with CP-ABE [8] such that re-encryption keys are computed by the cloud provider based on a secretFile Size: KB. In these paper encryption techniques such as proxy re-encryption (PRE) scheme, Type based PRE, Key-private PRE, Identity based PRE, Attribute based PRE and Threshold PRE are discussed. The paper has been organized as follows. In section II cloud architecture is discussed. In section III the Proxy re-encryption techniques are discussed.

A proxy re-encryption (PRE) scheme supports the delegation of decryption rights via a proxy, who makes the ciphertexts decryptable by the delegatee. PRE is useful in various applications such as encrypted email forwarding.

Index Terms—Proxy re-encryption, cloud storage, identity-based encryption, broadcast encryption, secure cloud email 1 INTRODUCTION Intermediary re-encryption (PRE) [1] gives a safe and adaptable strategy for a sender to store and offer information.

A client may scramble his record with his own open key and afterward store. W e define our new notion of conditional proxy broadcast re-encryption as follows. Definition 2 A conditional pr oxy bro adcast r e-encryption scheme consists of the following algorithms.

When using traditional IBPRE for secure social cloud data sharing, there exists a dilemma which cannot be avoided. As Fig. 2 shows, data owner Alice first encrypts her private photos A/B and then outsources them to the cloud. Later, she wants to share only the photo A with friend Bob by using traditional identity based proxy by: 6.

In this paper, an identity-based conditional proxy re-encryption (PRE) scheme is proposed, where a delegator provides a re-encryption key satisfying one condition to a semi-trusted proxy who can convert a ciphertext encrypted under the delegator’s public key into one that can be decrypted using the delegatee’s private key.

Furthermore, the. data owner can offload most of the computational operations to the cloud service. Use proxy re-encryption. In this case, I retrieve Bob’s public key, and issue a “re-encryption” key.

Improved Proxy Re-Encryption Schemes with Applications to Jakobsson [28] developed a quorum-based protocol where the proxy is divided into sub-components, each controlling a share of the re-encryption key; here, the keys of the delegator are safe so long as some of key data in a single location makes for an inviting target.
